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 can boast of a variety of not only the 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:

Open intercom lock Barrier without key

If you have come across this old intercom you're lucky.

Perhaps even lucky twice.

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

In addition, there are simple, purely physical ways to 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 installed device. Just there the electronics of the device should be located, and you will have a chance to close the intercom circuit.

Have you looked into your bag and looked in horror for the keys to the intercom that you forgot at home? Almost every owner of this type of security faced a similar situation. As a result, I had to wait hours for neighbors from work or run for a spare key. If a Cyfral intercom is installed in your house, then closed door- It's not a problem. There are several ways to get home. To do this, you need to know a few secrets on how to open a Cyfral intercom without a key.

Varieties

Intercom Cyfral - domestic products that have already proven themselves as quality device. These equipments are constantly being improved, new technologies and functions are being introduced.

There are several varieties of Cyfral intercoms.

In case the keys are lost, there are standard combinations that will open the doors.

Important! Standard code does not always help. During installation, specialists can change it for security reasons. That is why do not be lazy and learn a new combination immediately when you connect Cyfral in your home.

Opening without a key

Method 1

The spare code for the Cyfral intercom even depends on the apartment numbers. If the numbering of your apartment starts from 100 to 999, then it will be easier to open the doors.

We open the doors by the selection method (KV - Call button):

If all these universal codes did not help or the apartment numbers consist of two digits, then the other methods listed below will come in handy.

Method 2

If the Cyfral intercom model number ends with "M", then the following combinations can help open the doors:

1. Call button - 41 - call button - 1410.
2. 07054.

Important! If none of the combinations helped, the universal combination was changed.

Opening of the Cyfral CCD-2094 model

Intercoms Visit are the most common electronic intercoms in Russia. They are opened by using contact key tablets and contactless magnetic cards. In the absence of an electronic identifier, it is possible by entering a special code. At the same time, it must be remembered that hacking an intercom A visit for mercenary or criminal purposes is punishable by law.

The Vizit intercom has several modes of operation: normal, maintenance mode, changing settings and programming. Access to the operation of each mode can be obtained using special code combinations. With the release of any model, a factory code is set. It is operational until changed. The default password can be changed during system setup.

Code combinations for keyless entry

If the subscriber does not have an electronic key, then a completely logical question arises: “How to hack an intercom using special code combinations?”. To open an intercom Visit, you need to make more efforts than to open similar equipment from another brand. hallmark device is that the * and # keys may not be available on the call panel. Instead, there are buttons C and K, respectively.

If the standard did not change during the installation work by specialists, then to get keyless access, you can try entering the following combination:

• Dial * - # - 4230;
• Enter 12 - # - 345.

These ciphers are usually standard for devices equipped with LEDs that do not have a display. To use a special code to hack newer models of equipment, you can enter one of the following digital combinations:

• On the calling panel, enter * - # - 423;
• Dial 67 - # - 890.

Using special code, you can access the service menu of the Vizit intercom device. To do this, press the # key on the call panel (if it is absent, press the K key). Then enter digital password– 999. After completing these steps, a double call should follow. Next, you need to enter the standard master code 1234. If the code information is correct, then one beep will follow. If the password is entered incorrectly, a double beep will sound. Depending on the specifics of the installed equipment model, the standard master code may be different, for example: 6767, 3535, 12345, 9999, 0000, 11639.

Alternative ways to open the intercom

Hacking or reprogramming intercom equipment is always a challenge. This is primarily related to functional features mechanism. Also, the hacking process is affected by changing the factory settings when installing the equipment. If, nevertheless, one of the above codes came up, and the service menu was entered, several operations can be performed to change the device firmware.

To do this, follow these steps:

• On the calling panel, press the number 2;
• Then the # button;
• Enter the combination 3535.

When entering the service menu directory, each digit on the call panel displays a specific subdirectory. To enter them into the device memory, after entering this section, bring a new identifier to the reader and simultaneously press #. When a short beep is received, press * to complete the recording process. Pressing the number four on the entry panel will enter the subdirectory for deleting all existing keys from the intercom's memory.

To complete the program settings and exit the service menu, press *, and to confirm and save the changes, press #.

Not always the above special passwords will be able to provide access to the premises. If the code was changed during the installation of the device, then you can find it out only from the specialists who installed the equipment. For access without using the identifier that came with the intercom, you can order a universal key. Information containing several special codes is programmed into it. With it, you can open several intercoms of the same brand. Appearance such a universal master key is no different from a conventional magnetic key.

The video shows the code in use:

If you forgot or lost the key to the entrance, knowledge of the service intercom code will help keyless open the door. But the number of companies producing access devices is large. We will focus only on those that are popular in our country.

What is an intercom?

Intercom (intercom system or intercom system) is a set of devices that restrict access to the premises. As a rule, it consists of the following components:

• Lock. The predominant type is electronic, however, on some models, electromechanical can be installed;
• Communication block. Allows you to establish an audio (in some modifications - video) connection between a certain apartment and a visitor who is located at the outside front door.

Modern devices have additional features, such as:

• installation of a fire or burglar alarm, connecting it to the console of the relevant structures;
• emergency call from the rescue services device;
• face recognition function (on certain models equipped with video surveillance).

The degree of functionality and additional features of the system depend on the wishes of the customer and strongly affect the final cost of the installed equipment.

A bit of history

Since ancient times, humanity has tried to protect its personal property from external encroachments. Inventing various devices and devices that prevent the penetration of "strangers" into the home.

The discoverers and inventors of complex locking devices are considered to be the ancient Chinese (where without them), the Egyptians and the inhabitants of the interfluve. Approximately in the same period, they independently developed the first castles.

First of all, access restriction devices were necessary for the rulers of states who wanted to ensure the safety of their treasuries. Stored wealth pushed others to illegal actions - it was impossible to fully trust anyone, even close relatives.

The first copies were made of wood. For several centuries, wood has been the main material for making locks. Yielding, in the future, the championship of metals and alloys.

The oldest is found on the territory of modern Iraq at the end of the 19th century. exhibit. Archaeologists estimate its age at 2700 years. Represents wooden box, inside of which there is a movable bolt that locks the door.

With the development of metalworking, combined locking devices appear - wood-metal. In such locks, the key and latch were made of metal (or alloys) and the body remained of wood. Such specimens were used in Ancient Greece and Rome.

The so-called "Roman castle" was distinguished by a massive key made of bronze. It was the first to use the principle of "rotation" of the key, the device contained spring components.

In medieval Europe, iron was used in the manufacture. The most common were padlocks 2 types. Their name was geo-referenced:

• "Deutsch" lock type. Distinctive feature is the end of the bolt beveled at an angle and the spring fixing it in the “closed” state. To close such a lock, it was enough just to slam the door. When unlocking, turning the key (just over 90 degrees) moved the locking plate, compressing the spring.
• "French" . It had a spring that prevented the bolt from accidentally moving. When opened, the key turned a few turns.

The technical revolution of the XIX-XX centuries. introduced innovations in the design of locks. New types and species are emerging. In addition to mechanical, electronic, code devices are becoming widespread. Which can be opened by entering an alphanumeric sequence, a magnetic card, a fingerprint, etc.

To restrict access to entrances apartment buildings intercom systems have been developed.

Classification

All devices are classified according to:

• The number of connected users.
• Video transmission capabilities.

By the number of connected users, intercoms are conditionally divided into 2 large groups:

• With a small number of subscribers - they are individual devices. Are established on entrance doors in private houses, small firms.
• FROM a large number subscribers. Used at the entrances of high-rise apartment buildings.

When possible transfer video signal allocate:

• Audio intercoms. With an incoming call, the user of such a system has only an audio contact. The advantages of this type include low cost and ease of installation of equipment. The disadvantages are the lack of eye contact and insufficient security (by calling any apartment and introducing yourself as a doctor, police, etc., you can enter the entrance).
• Video intercoms. Provide eye contact with the caller. The equipment of such an intercom contains a video camera with IR illumination. It is allowed to mount several cameras that give a picture from different positions, which is a “plus” of the system. Another bonus is the ability to connect recording devices, which will allow round-the-clock video recording of what is happening. The only downside is the cost of the equipment.

What does the intercom consist of?

The intercom system is a complex of equipment, the constituent elements of which are:

1 The main unit (panel) to call. It is located on the front door or next to it. Allows you to enter the premises or call a user who lives in the house. It is protected from vandals. Comprises:

• - buttons with numeric characters for dialing, call and reset buttons. All buttons have a backlight function;
• - speaker and microphone, which provide audio contact between the subscriber and the visitor;
• - a device for reading a key (card);
• - in models with video communication - a surveillance camera.

2 Switching device. Represents internal organization, which connects the input unit to the intercom inside the apartment when dialing. Outwardly, it does not stand out, it is the electronic filling of the intercom.

3 subscriber's device. Located in the apartment, it is an intercom that allows you to communicate with visitors. It looks like a handset (if video communication is supported, there is an LCD screen). Includes button for remote opening of front doors.

4 Lock. It is connected with the main unit and the switching device, it receives commands to open them. The complete set depends on the intercom model and can be represented by both electromagnetic and electromechanical devices. The disadvantage of the first is the complete dependence on electricity in the network. When it is turned off, the door will automatically unlock. Also, this type of lock is relatively easy to disable. The advantages include ease of manufacture and durability due to the absence of moving parts, low price.

How to open a door with an intercom?

It is possible to open the entrance door equipped with an intercom in several ways:

• The introduction of a digital sequence. These codes can be individual for the residents of each apartment, or common - all residents in the entrance use the same combination. The latter option reduces the security of the intercom device, because. "owners" of the password very quickly becomes a large number of citizens (friends, relatives, colleagues, etc.). Individual passwords are more secure and protected from unauthorized use (the number of "initiates" depends only on the tenant). At the same time, in certain models, the subscriber receives a sound signal to the internal device, warning that someone used the apartment code to enter the entrance. In addition to the above, there are also "service codes". Their use is limited to a certain contingent. Such passwords are used by district police officers, doctors, and public utilities employees.
• Magnetic card. It is applied to a special reader on the call panel.
• Using the subscriber's device, which is located in the apartment. With an incoming call, the subscriber presses a button on the device, giving a signal to the lock to open.

If everything is clear with the last opening option, then we will consider the first 2 in more detail.

Codes to open

There is no universal sequence that could open any door - this is an axiom. But different manufacturers have certain "factory" codes inherent in a particular brand.

We have prepared an overview of such codes that will help open the doors to the entrance of the house in case of loss or lack of a key.

When installing the equipment, the installer may change the factory settings. If the above combinations are invalid, contact your intercom company and ask for an access code.

Useful table

Keys and duplicates

The biggest misconception of most people is the opinion of degaussing locking device in the process of "attaching" the key to the reading device.

In fact, everything is much more complicated. The key is a small microcircuit, devoid of energy supply. The microcircuit contains a certain code, the data of which is registered in the memory of the intercom itself. When imposing, the code on the carrier is checked against the data in the database. When matched, the doors will unlock. The reading process takes 1-2 seconds. Codes can only be changed by software. This principle of operation is the most "popular".

There are also other types of keys that are used in intercoms.

• Contactless - allow you to open locks remotely. This type is less common, but has a higher degree of protection. Looks like a keychain.
• Resistor Keys - the access code in such models is the capacity of the installed resistor. The degree of protection is low, it is easy to make duplicates.
• reed switches - are a pair of magnets. One part of the reed switch part is contained in the key, the second in the main intercom unit. The degree of protection is also low.
• Optical - is a plate with applied micro-holes. Sufficiently high degree of protection against forgery. The disadvantage is the rapid contamination of such a key, which negatively affects its performance, and frequent replacement is necessary.

6 secrets you need to know

For a complete understanding of the problems associated with the keys of intercom systems, we have selected for you the answers to the most exciting questions.

Secret #1

Key, "blank", clone - the basic concepts. The key contains a certain digital sequence required to open the intercom lock. This unique combination is prescribed at the factory. A clone is a copy of the key, which is made in the workshop by your order. A blank is a blank that does not contain data and is used in the production of duplicates (clones). There are blanks different type– with and without overwrite capability. Sometimes, erroneously, they call a blank a duplicate that is not recorded in the device’s memory, which is fundamentally wrong.

If several copies were made from one key, all of them will have the same access rights along with the original. Additional steps to download data to the intercom system are not required.

Secret #2

One key can be used to open multiple systems. Factory keys, as noted earlier, contain certain codes. When reading them, the intercom system checks the code with the one in its database. Therefore, in order to be able to use the key on several devices, it is enough to enter your key into the memory of intercoms. At the same time, the “tablet” itself does not need reprogramming.

In this case, consider one "BUT". All devices must be of the same manufacturer, otherwise recording in the intercom memory will become impossible.

The same applies to the so-called "blanks" - blanks for forming keys. An empty key must initially be “endowed” with a code using special software tools, and only then, enter the entered sequence into the intercom. Which is not able to program the "blank" on its own.

Why is it so easy to get into service mode? But because when installing the intercom, the installation master was too lazy and did not change the standard code from the manufacturer. Therefore, I advise you, if you find that your intercom has standard settings, I recommend changing the entry code to the service mode. Below in the article we will consider the codes with which you can open the doors of most intercom models known to me. But I must say right away that there is no universal password.

Open without visit key a little more difficult, because they do not have * and # keys, instead you need to press C and K. If the factory settings have not been changed by the installer, then the door can be opened by entering * # 4230 or 12 # 345. You can also try this combination * # 423 or 67 # 890

To enter the vizit service menu: press:

#999 then wait for two short beeps,
and then enter the master password (1234 - but it can be changed by the installer).

The intercom should answer with one short beep. If the combination does not match, then the signal will be two-tone. In this case, you can try some standard master passwords - 6767, 3535, 9999, 0000, 12345, 11639.

So, we were lucky, we got into the service menu, what can be done.

Press 2 - pause - # - pause - 3535 - and the door to the entrance opens without a key.

By pressing button 3 in the service menu, you can put the key to the reader, press # and wait for the beep. Now, with this key, you can always open the door.

If you press the 4 key, then all keys will be erased from memory

* exit from the service mode.

# commit changes.

How to open "Visit" BVD-3xx. To open the door, press 1, after entering the service menu

The first option, if there are apartments in the entrance with numbers that are a multiple of 100 (100, 200, 300), then enter the combination as follows: call key and code 1 call key and code 2. Instead of code 1, enter the apartment number that is a multiple of 100, and instead of combination 2 - 2323, 7272 or 7273.

Applicable to Cyfral with M prefix next rule: call key + 41 or call key + 1410. On some models, the door can be opened by entering 07054.

Intercom Cyfral CCD-2094.1M.

You need to type the following on the keyboard<вызов + 0000>either the door will open immediately, or you will get to the service menu and the word ON will light up on the display, then press the number 2, after which the door should open.

If the display shows OFF, the quick entry mode is disabled.

Secrets of Cyfral CCD-2094M Dial the same way<0000 + клавиша посылки вызова>. The display should show . Then enter 123456+<Вызов>or 456999+<Вызов>, in some cases the combination 123400+ helps<Вызов>. We wait a few seconds. If the display lights up , then we are in system menu To open the door, enter the combination 601.

In order to add your own key to the memory, press the call button and without releasing it, wait for the message to appear on the screen about entering the service mode. Then we press<пятёрку>and enter the number existing apartment. TOUCH appears on the display. As soon as this happens, we bring a new key. Sometimes, instead of the apartment number, you can try dialing 600, then attach the key and the call button.

Metacom is opened in accordance with the algorithm: press the call key, then enter the number of the first apartment in the entrance and again send a call. The display will show "COD". After that, enter - 5702. If it didn’t work out, then try another option: 65535 + call + 1234 + call + 8 or 1234 + call + 6 + call + 4568.

The secret combination Metakom MK-20 M/T is “call button + 27 + call button + 5702” or so “call + 1 + call + 4526”.

We press button C and wait for a squeak. Then enter the service combination.
