Intercom lock codes. How digital intercoms of different models open

In everyone's life, a situation is possible when he finds himself at the entrance with an intercom without the opportunity to enter. It could be his own porch. You never know. Maybe he lost the key fob, or maybe he fell into disrepair. At such a moment, knowing the code is an urgent need.

Our article will help you open the door with an intercom without a key.

Keyless Entry Codes

An intercom is usually installed to protect the entrance from the presence of strangers. And since it is a security device in itself, manufacturers put a lot of effort into protecting it from possible hacking. So the use of any codes is possible only if the factory settings are preserved.

But remember, the use of codes for selfish purposes to open intercoms without a key is a criminally punishable act. Therefore, use this information only in situations of emergency.

How to open the door without a key from the Eltis intercom

The devices of this company are distinguished by the rare simplicity of factory codes. To unlock the lock, one of these codes may be suitable:

If the combinations do not fit, try replacing "100" with "200", "300", etc.

If these combinations do not work, use the recommendation for Cyfral.

How to get into the entrance with the intercom Cyfral

When there are apartments with numbers divisible by 100 in the entrance with the Cyfral device, then there is a chance to open the intercom using the code:

Devices Cyfra with "M" in the markings open:

Cyfral CCD-2094M opened from the menu:

First "0000" and the "Call" button.

Then "123456", "Call" or "456999", "Call", or "123400", "Call".

Wait 5 seconds.

If/(when) one of these codes matches, “F0” will appear on the display. It means that the device has switched to the mode we need.

Now - "601".

And the door can be opened.

Worth highlighting model CCD-2094.1M. It differs from other devices of this line by the presence of a constantly lit or flashing dash on the display. It's harder with her.

The castle opens.
"ON" will light up - this means that you are in the menu. Press "2", and - congratulations - you have opened the door to the entrance with an intercom.
Written "OFF". So the settings have changed.

How to open the Vizit intercom door

But Vizit devices boast a variety of not only model range, but also special codes. Finding the right one even with working factory settings may not be easy.
In addition, in some models, the "*" button replaces "C", and "#" - "K".

So, the codes to open the Vizit intercom:

If their thoughtful search did not bring any results, you will have to go the long way - through the service menu of the system:

"#999".

Wait for the beep (two beeps).

Enter the master code, to begin with "1234". The device should beep again. If the code is incorrect, the sound emitted by the device is two-tone, and you'd better try other combinations:

After entering the menu, you can:

Open the intercom without a key with the code "2" - pause - "#" - pause - "3535".
Or programming the key fob.

For programming:

Press "3".
Bring the tablet key to the reader.
Press "#".
Wait for the beep.
And from now on, your key will open this intercom door.

Key "*" - exit from the mode.

It will be more difficult with "Vizit" BVD-3xx. It has neither a monitor nor any indication.

According to the algorithm described earlier, you will need to enter the service menu and unlock the lock by pressing "1".

How to open a Metakom intercom

The company produces digital addressing units (intercoms) and outdoor subscriber panels.

First, let's look at how you can open the entrance with a Metacom intercom without a key.

"Call", enter the number of the first apartment in the entrance, and press the call button again.
“COD” should light up on the screen.
Press "5702".

If it doesn't work, try two other schemes:

The Metacom MK-20 M/T model is not programmatically protected from the master key. Therefore, if you attach a "clean" key fob to the reader, it will immediately go into programming mode. In the absence of a key fob, you will have to deal with the keys. Codes:

The method of opening the door with a subscriber panel for 20 subscribers, you can see in this video:

How to open the intercom door Factorial without a key

And although in terms of factory settings, Factorial is very similar to Cyfral, the mandatory change of special codes by installers spoils the whole picture.
Still, try:

But for this manufacturer, no one, except for overly conscientious installers, worsens the statistics:

It is important to make the last pressing of the call button quickly.

Open intercom lock Barrier without key

If you have come across this old intercom you are in luck.

Perhaps even lucky twice.

Because finding one is like meeting a dinosaur, they are so rare.

In addition, there are simple, clean physical ways open any intercom without a key:

Apply force. Most locks on intercom doors are magnetic. And with a sharp jerk, there is a chance to open the door. In principle, the efforts of one person should suffice. Although it is more reliable to do this with two or three people. And remember, the main thing is the sharpness of the jerk.

Open the intercom lock with a stun gun. Attach it to the reader and give a discharge.

You can try to open the door by hitting 10-15 cm below the installed device. Just there the electronics of the device should be located, and you will have a chance to close the intercom circuit.

Information on how to open an intercom without a key will come in handy if you lose a standard device to access your own entrance. They cannot be used to commit illegal acts. However, it is better to save the data necessary for personal use in the memory of the smartphone. They will help you solve the problem if the situation arises.

With the use of the Wof-Hu energy strike, you can quickly open the door to the entrance. Before mastering this effective methodology you can use the instructions in this article

These handy devices installed as standard when equipped apartment buildings. They perform several useful functions at the same time:

provide communication with desired apartment(audio and video);
allow remote control of the locking mechanism;
lock it on.

This figure shows the main components of the standard equipment. The call block is installed on the outside of the front door. It has keys for dialing the apartment number, a special contact pad. An electronic key fob (“tablet”) is pressed against it to unlock the electromagnetic lock. The control unit checks if the code of this key matches the sample. From the inside, you can turn off the power supply to the lock and open the door using a special button.

It is known that utility workers have access to entrances with various intercoms. They do this using several methods. Their detailed study will allow you to figure out how to open the intercom door without a key.

The principle of operation of the intercom - device, encoding

When you press a button on the call unit, the signal through the switching unit goes to the handset in a certain apartment. IN this example tens and ones buses are used to connect subscriber units. Digital switches are also used, which form a coded signal. In this option, it is possible to connect more than 200 apartments using a two-wire communication line.

After removing the tube, you can find out the purpose of the visit. If necessary, a return signal is given by pressing the button. It removes the voltage from the electric magnet, after which the door can be opened.

The case is well protected from atmospheric and mechanical influences. As a rule, the manufacturer offers an anti-vandal design that makes even intentional damage difficult. The loudspeaker (1) is covered by a strong grille. The microphone (5) is hidden behind a narrow opening. Some models have infrared illumination (2) and a camera for video monitoring. A “tablet” or other specialized device is applied to a special platform (6), in which the code for opening is recorded.

Built-in indicators (3) display not only the number of the called apartment. In the appropriate mode, they show the codes that are needed for setup. On the keypad (4), the following type designations are used:

"FROM"– to clear incorrect input;
"B, or bell symbol"– call;
«#» – when entering service codes.

In addition to the power supply printed circuit board install several functional parts:

contact pad for buttons;
a memory chip in which codes and set settings are stored;
information processing unit;
transmitting and receiving paths of audio and video signals.

The main ways to open the intercom without a key

The above information allows you to draw the right conclusions about suitable techniques. The codes are stored in memory in encrypted form, so even if you open the case from the entrance, you will not be able to make changes to the settings without special knowledge. You will also need a special device (programmer) to erase old and enter new data into memory.

We are considering more difficult task how to get access from the outside with the condition of the safety of the hull.

The picture shows classic "pills" (1) and more modern non-contact modifications (2). The first are applied tightly to a special nest. The latter also need to be pressed to a special platform, but less accurate actions, small gaps are acceptable.

The second way is to enter the unlock code that opens the door, or access the service menu. The second option opens up additional possibilities for fine-tuning equipment. We note right away that sorting through various combinations manually will not work. In modern intercoms, complex coding is used, which will have to be decrypted with a similar technique for many months. Some manufacturers install special protection that blocks access to the system when such actions of intruders are detected.

Below is how to open any intercom without any extra mental effort. It should be emphasized that these methods do not always help to obtain the desired result. They can damage the door itself, the intercom electronics. However, for the sake of completeness, here are the necessary steps:

Is it possible to make a universal key for an intercom with your own hands

Meanwhile, if you contact a specialized workshop, you will be offered just such an option. The fact is that each manufacturer creates a unique coding system. The same types of keys can be used. But you will have to purchase those that are suitable for a particular intercom model.

Thus, "universal" tablets for employees of a service company, public utilities open devices only from specific manufacturers. Moreover, quite often their effectiveness is limited by the region, product series.

To reproduce this design on your own, you need certain skills. Controllers are installed here for reading information and connecting to a PC via a USB port. The device is capable of copying data from a working key.

Its free programming is also available. In this option, you need to find out which algorithm the manufacturer uses. If needed universal key for the intercom "Metakom", you should take into account the features of the continuous supply of the code with a change in the current consumption / resistance. By default, a packet of 4 bytes is sent, one of which is needed for parity. It remains to be found on the Internet valid code and write it to the device memory.

For your information! When purchasing such products, you should make sure that they are compatible with the right types intercom keys.

How to open an intercom without a key: unlocking products from different manufacturers

If we exclude the barbaric methods of the “no technique against scrap” category, what remains is the study of complex electronic circuits, soldering techniques. You will have to purchase additional equipment, learn the basics of programming. The purchase of factory programmers and duplicate keys does not make sense to consider in detail.

This technique is designed to work with a single user, so there is no keypad. Therefore, there is no possibility of manual input. In multi-apartment buildings, such systems are installed at the entrance with a concierge, who is on duty around the clock. The only access option is to make a duplicate of the original key.

hard to find modern door in the entrance of a high-rise building, unprotected by an intercom. These devices are easy to use and pay off fairly quickly. Their main function is to provide access inside the house exclusively for residents and their guests. But situations are different, and sometimes it is necessary to open the door, but there is no one to call. How to find out the intercom code and get inside the entrance?

Master key or code?

The easiest way to open a door with an intercom is to use a universal key. Similar products are made for a nominal fee by some craftsmen, issue them legally to employees of a number of services. A key that can open any door can be held by ambulance doctors, housing and communal services workers, police officers and representatives of a number of other social professions. In fairness, it should be noted that such keys have a specific shape and are suitable, respectively, only for some models. protective devices. Is there a universal code for the intercom? Unfortunately not, but each manufacturer has its own factory settings. If during installation they were not changed by the wizard, you can try to open the intercom without a key.

Opening Vizit

The most reliable, and therefore the most popular in our country, are Vizit brand devices. Today in many cities you can find at least 8 varieties of intercoms from this manufacturer. They differ significantly appearance. Moreover, in some, in addition to numbers, the symbols “*” and “#” or letters are used. How to find out the intercom code of this brand? Everything is quite simple. For devices that are several years old, you need to use the combination "asterisk-pound" and dial the numbers 4230. Alternative: 12, asterisk-pound, 345. New electronics of this brand should be opened by the first version of the code without zero or the following combination of characters: 67, asterisk- lattice, 890.

Intercoms Eltis and Metakom

The devices of these two brands are almost as common as the "Visit". The easiest way is to open Eltis. You don't need to remember long passwords. We press the call key to the apartment, then dial "100", call again and after that - 7273. If the door does not open, try changing the last digits to 2323. How to find out the Metacom intercom code? It's a little more complicated, but also quite realistic. Option for the lazy: press the call button, enter the number of the first apartment in the entrance, then call again, after which we enter the combination of numbers 5702. Another option: 65535, call, 1234, call, 8. If this code also did not fit, try dialing 1234, call, 6, call, 4568.

How to open the door if you can't pick up the code?

The intercom consists of an intercom, a processor and a magnetic mechanism that blocks the door. Brute force will not help, the magnetic field is too strong and can withstand several tons of pressure. It turns out that it is impossible to open the intercom without a key and code? Engaging in the selection of a combination at random is a thankless task. The standard ten digits and two system buttons offer an almost infinite number of combinations. If you need to get to the entrance quickly, you can try to call any apartment at random. Further, it all depends on your imagination - introduce yourself as a postman, a neighbor or a courier from a second cousin, but there is no guarantee that they will open it for you.

Do not forget that the intercom is an electronic device. If there is a power outage at the entrance, you won’t have to open anything special. An alternative option for opening the intercom is to try to shock (a regular lighter is enough) in the place for the key. Some models open the door after such exposure. If you have access to the device's power supply, you can try disconnecting it from the network, and then reconnecting it. Such a simple manipulation will cause a serious failure in the system and you no longer have to puzzle over how to find out the intercom code. But keep in mind that such actions will lead to serious damage when the device cannot be repaired.

Modern residential buildings, both multi-apartment and not, it is impossible to imagine without an intercom. Small but effective and practical device greatly facilitates control over the entrance. One of the most popular devices of this kind today are the products of the Russian group of companies Metacom.

Intercom Metacom is different modern design and technical specifications comparable to the best examples Western production.

In most cases, the intercom controls the lock front door using a key or a signal from the apartment. But sometimes you need to open it without a key, that is, hack it.

To find out how to open a Metakom intercom if the key is not used for some reason, carefully read our article.

Types of intercoms Metakom

Metakom intercoms have been known on the market for 20 years and occupy a worthy place in consumer ratings. The company's engineers are constantly improving the technology and design of equipment. The key to reliability and durability of work is a three-level quality control. Several types of intercoms are available:

Audio intercoms. Single-end devices are the most affordable duplex-type devices. With their help, a call is made to the subscriber, two-way communication is provided and a signal is sent from the apartment to open.
Video intercoms. Approximately the same device, but with the ability to conduct video communications.
Multi-subscriber. Depending on the model, connection from 10 to 999 subscribers is provided. There are two types: coordinate and digital. To use the first one, the button located opposite the apartment number is pressed, and when using the digital model, the number of the called apartment is dialed.

A multi-subscriber intercom is the simplest device that effectively restricts access to the entrance apartment building. Metacom is easy to connect. A specially designed scheme allows even a non-specialist to do this.

Models are available with indicator lights to make it easier for people who are hard of hearing to use. Devices with the function of selective shutdown of subscriber sets and return to factory settings are also produced.

Design and principle of operation

The Metakom audio intercom consists of a built-in call panel installed with outside entrance door, subscriber unit or handset, which is mounted in the apartment, a switch that provides communication between them, and an electromechanical lock. The call panel and handset are equipped with microphones. The call is made by pressing the corresponding button on the panel. The call panel has a loudspeaker. The subscriber handset is arranged in the same way as the handset landline phone with the same features.

The door is opened remotely by pressing a button on the handset, a magnetic key is used, or when a special code is entered on the call panel. Some models support the intercom function - communication is carried out with several subscribers at once.

His videophone kit includes a monitor, which can be color or black and white, as well as a panel with a video camera. The camera turns on automatically when a call is activated and turns off after a certain delay after the call ends. It is also possible to connect an additional video camera at the request of the client.

An analog or coordinate matrix multi-apartment intercom is the most common these days. Each subscriber has his own key. The device requires laying two wires to each apartment.

Digital is functionally not much different, with the exception of coding apartment numbers. A binary key code is used for digital data transmission.

The wiring in this case consists of a single two-wire wire, and the number of switching errors is reduced to a minimum. In addition, the digital device has the function of communication with the dispatcher of the service company.

Residents gain access to the entrance by entering a PIN code or a special key. Visitors enter only with the permission of the tenant after identification through two-way communication.

Advantages of the intercom Metakom

One of the most notable advantages of Metakom is a molded waterproof case made of durable material. It firmly protects the device not only from water, but also from intruders who may try to break into the box. Other benefits include:

Good memory capable of holding several hundred keys.
High quality backlit keyboard.
Possibility of connection of signal amplifiers.
Function of communication with the dispatcher.
Ability to connect up to 4 surveillance cameras.
The almost complete absence of mechanical switches, which excludes blocking of the device buttons or oxidation of contacts.
Easy to open with Touch Cyfral, Touch Memory or digital code.
Possibility of programming.

Ways to open without a key

As with any other intercom, there are several of them. There is no 100% chance of triggering, so they are used in order. The most efficient ones are:

The number of the apartment is dialed (your own, a friend or even a stranger) and the call button is pressed. On Metacom models, it is indicated by the letter "B". Someone will open it.

The universal code opens the intercom without problems. If during the installation process it was not changed by the installer or residents, then the default combination of 1234 and "B" is dialed.
The second way - the call button is pressed and the number of the first apartment in the entrance is dialed. The inscription COD will appear, after which the combination 5702 is dialed. The door should open.
The third way - the combination 65535 is typed and "B" is pressed. After that, 1234 is immediately dialed, again “B” and the number 8.
Another way is to dial 1234, press "B", number 6, press the call button again and the combination 4568.

These methods are suitable for keyless opening of devices with indicators. The following are suitable for a doorphone without a display:

"B" is pressed and 27 is entered, then the call again and 5702. After two seconds, the intercom will open.
Or the "B" button is pressed, followed by dialing the number 1, again pressing the call button and dialing, press B and 4526.

Special codes can be changed in the software settings. To do this, enter the menu. First, 65535 is entered, then the “B” button is pressed, then the known valid master code is entered and the call button is pressed twice. After that, a new code is entered. In order for it to remain in the device’s memory, “B” and the number 7 are entered. To unbind all codes from the apartment, the following combination is dialed: “B” and the numbers 70111 in sequence.

Universal code functions

Intercom Metakom determines for each subscriber its own key code of four digits. Every tenant needs to know it, otherwise it will be very difficult to get home without a key. Usually, it is indicated in the service contract by the manager or the company that installed the device. You can find out the treasured numbers in this very company.

In addition to access to the entrance, the universal code provides the following functions:

Changing and setting a new master password.
Binding or unbinding the key to the apartment.
Change the system settings of the intercom.
Electronic lock programming.

Entering the master code opens the door and enters the settings menu. There are three types of them:

Service.
Systemic.
Custom.

To enter the system settings menu, just dial the combination: 65535, Call button or "B", 1234 (key code), call again and number 9. Entering the service settings menu is as follows: dial 65535, then call, code 1234 and challenge again.

To enter the user menu, a combination of numbers 65535 is dialed, then the call button is pressed, the key code 1234 is entered, after which the "B" button is pressed twice.

Some models can be opened with a magnetic pick or tablet, as such a key is also called.

On the video you can see the methods of hacking the Metakom intercom:

Such tools usually fit several brands of intercoms. various manufacturers. But only after entering the identifier code into the device's memory. This is done by service companies, and the key is provided to the police and the Ministry of Emergency Situations.

The master key is used as the original key. The built-in circuit with code information has a number of factory firmware, which in most cases ensures that the programmed and provided data match.

In any case, the intercom is a complex device. If something doesn't work, don't get upset. Attached to it detailed instructions which can also be found on the internet. If you have lost your key or cannot find it, neighbors can come to the rescue. IN last resort, you can call specialists from the service company and ask for a new key. You can also order a duplicate key.

Many are interested in the question of whether it is possible to somehow open the Vizit intercom without a magnet, because this intercom model is considered the most reliable. They helped prevent many burglaries and thefts, so they began to be installed in most high-rise buildings.

Intercoms Visit

Vizit equipment is perfectly adapted to work in the harshest conditions. The case of the intercom Visit has a high-quality anti-corrosion coating. Studies have shown that this equipment can be used at temperatures environment from -30 to +40. In addition, they are resistant to high humidity which makes these intercoms even more reliable. Vizit can work for more than 12 years, which is enough for them to be recognized as stable devices.

How to open an intercom Visit without a key using the service menu

If you have forgotten or lost your house keys, do the following.

Enter the service menu code with which you can hack the device. To do this, dial #999 and enter the service mode. Wait for 2 beeps and enter the password. The factory password for all intercoms of this model is the same 1234.
If you entered the password correctly, the device will beep 1 time. If the password is incorrect, you will hear a double sound signal. Try to enter more such password options - 3535, 9999, 6767, 0000.
Entering the service mode will have to perform the operation a little more complicated. To open the door enter “2”, pause for a couple of seconds “#” and “3535”.

If you press “3”, you can set up new keys for the intercom. After pressing this button, put your key to the reader and press “#”. You should hear a squeak - done. With the button “4” you can erase all chips from the memory. An asterisk is an exit from this mode. Lattice - confirmation of the introduced changes.

How to open the intercom Visit with a universal key

This is already a hackneyed topic, but many still believe. Generating a master key is not possible. The intercom opens the door only with the keys that are stored in its memory. It does not contain any universal keys for special services - doctors, firefighters and police. We all could see the video on the Internet, where we are shown such keys. But how is this possible?

Each key has a static code that can be registered in several intercoms, at least in all. But who needs it? Each installation company installs several keys in 1 intercom. This is done to improve the convenience of service, so as not to wait under the entrance until one of the residents opens the door. Someone can illegally obtain such a key and sell it or use it for fraudulent sales. That's what video creators do - deceive people. Universal keys are never made in multiple copies, since every serious organization has its own universal key for pre-prepared objects. If such a key is sold, then the seller is obliged to warn you that the key does not open all intercoms and does not work in every city.

How to open an intercom Visit without a key - other methods

There are tips on the Internet - to open the door by force. Electromagnetic locks Vizit hold doors with a force of about 400 kg. If you are not a super-strongman, and the lock is set according to the rules, then nothing will come of it. Under correct installation refers to 100% sticking of the magnet to the door plate.

There are also absurd tips - to de-energize the entire entrance! According to commentators, you need to break the light bulb above the entrance and make a short circuit. All you can achieve in this way is injury. In most cases, the door will not open - the mains protection will work. The use of a stun gun is real option, but in modern intercoms Visit, protection against the action of such devices is installed.

The developers of the Vizit intercom provided for situations when a person needs to get into the entrance without a key, so they made their equipment very convenient. The standard access code can only be changed by a professional, while ordinary users have access to only some adjustments. If you do not want to carry several keys from the visit intercoms, contact a specialized company and they will make you 1 universal key for the intercoms you specified.
