Attention! Access codes are only suitable if the installers were lazy and did not change the default password. This happens quite often :)

Eltis intercoms

Initially, the default code is “1234”, but any company, when installing an intercom, naturally changes it to its own, and it is almost impossible to recognize it. To enter password entry mode, you must hold:
1) any number key for 7 seconds (menu "code" - menu for working on apartments, programming keys)
2) Button “c” - hold for the same amount of time (menu “sys” - general parameters, prohibition/enablement of codes - 1234 is quite often suitable for this menu, it worked for me 50 times.)

Explanation of menu operations:
1. Call the system menu "sys".
1) Press the “b” button and hold for 7 seconds.
2) After the inscription “SYS” on the display, enter the system password (stupid lazy system specialists often do not bother to change the password, which is the default - 1234)
2.1) If the input is correct, the intercom will display the firmware of the form “6_7x”, where x is the firmware number, after which the “_FUNC” menu will load.

From it press:
“1” - “PAS” will appear, after the input field for changing the old password to enter this menu (dial 4 digits and the intercom will return to “_FUNC”
"2" - menu "_ LOС" to enable/disable the general login password (buttons 1/0 respectively)
"3" - menu "_ dig" to change the general login password. Press 3, 4 or 5, "____C" will appear.

Depending on the button pressed, you can set a new password, respectively, 3, 4 or 5 digits. (type new password)
"4" - menu "_beep". This option turns on/off the signal for opening an individual apartment code in this apartment (the handset rings when opened with the default code, buttons 1/0)
"5" - does not exist
“6” - menu “_FLOC” for turning on/off individual entry codes for apartments (to check, press “in” in normal mode, if “F” lights up, it means it’s on)
"7" - does not exist
"8" - menu "_OPEN" - to change the duration of door opening (the number of signals will change, decrease/increase with buttons from 1 to 9)
"9" - does not exist
"0" - output

2. Intercom serial number.

Press "in" and hold for 20 seconds. 5 digits will appear and then reset.

1) Enter any NUMBER and hold until “CODE” appears, then a password entry field will appear.
2) Enter the system password (by default 1234 as in the first case)
3) If the input is correct, the firmware will appear, then the "_FUNC" menu.
4) From this menu:
"1" - Set a new password to enter this menu (same as the first case, see above)
"2" - Set a new general login password (4-digit).
"3" - work on apartment passwords:
"_FUNC"--> press "3"--> "F"--> enter the apartment number and press "c"-->"____C"--> enter a new code (but not 0000, because by entering it , you will prohibit the use of the code for this apartment)--> the apartment will be dialed--> ask to press the “open door” button TWO times--> the code is accepted, “_FUNC”.
“4”, “5” - menu “__ LF”, but different options are hidden under different numbers.
"4" - disable/enable individual handsets in apartments. Dial the apartment number, then press "in". “*** #” will appear, where *** is the apartment number, and # is the number 1 or 0 (on or off). Click the value you need.
"5" - key coding. Dial the apartment number and press the "c" button (see above). “***LF” will appear, where *** is the apartment number. Place the key against the reader. If you have not encoded the key before, the inscription “ADD” will appear; if you have encoded it, the number of the apartment to which the key is recorded will appear. After encoding, you can open the door with this key after logging out.
"6" - menu "__ dF". Option to delete keys. Type the apartment and press the "c" button. "_ dEL" will appear, press 1 - the number of keys that have been deleted will appear. (*dEL). Press 0 to exit to "_FUNC".

factory code 1234

VIZIT intercoms

To open the door, you can try dialing *#423. (not always suitable)
Entering the service mode is quite simple:
#999 - beeps 2 times - enter the master code, default is 1234, if suitable, beeps 1 time
if the code is incorrect, it will beep with a two-tone signal and the red LED will light up.
Explanation of operations (since there are few of them in the service mode, the explanation of the buttons is given here:
2-setting individual codes for apartments
3-key programming for entry
4-erasing keys from memory
*-exit mode
#-confirm installation (save changes).
1,5,6,7,8,9,0 - does not exist.
Try to encode the key for yourself (an example is provided if the master code is correct):
#999 (2 peaks) 1234 (1 peak) 3 (1 peak) (apartment number) attach the key (pick) # and then * .
VIZIT intercoms also have a special mode in which you can change everything, even the master code. The transition to this mode is carried out from the normal state as follows (taken from the instructions):
1) turn off the power to the intercom
2) disconnect the two “programming” wires in the central unit
3) turn on the power.
As can be seen from the above, the block with the buttons must be removed.

Digital intercom - a domestic product High Quality. It is considered one of the most reliable devices on the market. The manufacturer is quite serious, and therefore access to secret codes is quite reliably protected. In addition, installers are required to change the code service access to the device during installation.

Sometimes it happens that you can open the intercom knowing the factory settings. This may work if the code has not been changed. This remains on the conscience of the craftsmen, but for residents who left the entrance without a key, this is a significant find.

It should be noted right away that hacking a device is not so easy. The armored anti-vandal body is designed to resist street hooligans, and most often defeats them.

Most often, people are faced with a situation where the key is forgotten or lost, notebook I don’t have a written down code for each type of intercom at hand, but I still need to get home. What to do? There are various recommendations on this matter on the Internet.

Stun gun. It is believed that the discharge of a stun gun can replace the signal from the key fob. Knowing the principle of operation of the intercom and internal organization key, we have classified this method as questionable. The fact is that the key is also an electronic module that contains a rather sophisticated system of power supply, control and emission of a high-frequency signal. Moreover, each identifier has its own electronic signature. So decide for yourself whether a stun gun can replace a key. He might be able to burn the board. However, this is direct destruction of collective property.
Hit under the intercom in the area of the magnet holding the door so that it loosens its grip. The method is questionable. It is necessary not to hit the magnet, but to turn off the power.
A sharp jerk of the door away from you and towards you. Modern electromagnets have a force capable of holding up to 2 tons or more. If you are confident that you can create such an effort, then you can try. This method may work on older models. However, the new ones provide protection against such actions.
Lighter. This is exactly the advice that, in the old days, caused buttons to melt when trying to open them. door block. A modern intercom will not be fooled by a random, indistinct impulse from a piezoelectric element. It expects a clear combination from the key, a code that is written in the processor's memory.

These methods are practically ineffective and contain an element of vandalism. We do not recommend using them.

And now about humane and truly effective methods, in which there is no destruction or negativity, and which take care of the property of the house.

So, best ways for all types of intercoms at all times for positive people:

Call your neighbors or household members on the phone and ask them to drop off the key, which you will bring on the way to your apartment. Suitable in cases where the key has to fly no more than 3 floors, and there are no flower beds with shrubs below. Your household can lower the ID using an improvised parachute made from an ordinary package. This is in case there is no tube in the apartment.
Use the intercom and contact a friend or good-natured neighbor, asking them to open the entrance for you.
Wait for someone to pass through the door.
Find any apartment, introduce yourself as a postman, plumber, electrician, etc., and ask to be let into the entrance.

The disadvantage of this method can be considered the ability to win over people and build good relationships with them. However, in this case, you don’t need to load the Internet on your iPhone every time and try to find the secret code, which, moreover, most likely has already been changed and does not work.

Secret codes known to the Internet

It must be said right away that the code for opening the Digital device is usually distributed through social media former installers. Postmen and social workers most often they get into the entrances using the all-terrain vehicle’s universal key, whose code is already registered in the memory of the devices of this brand.

If you have a model with the letter “M” in front of you, then you can enter the entrance by entering a simple combination. Let’s immediately agree that in the formula we will denote the call button with the letter “B”.

07054-B
B-1410

If the “M” marking is not visible, then you can try the following combinations involving apartments ending with two zeros (“K”):

V-K-V-2323
V-K-V-7272
V-K-V-7273

If not a single code works, you can forget about tricky combinations and use the humane methods described above, or go to the company that installed the intercom at your entrance and order an identifier. Using a universal key, you can open not only your entrance, but also any device installed by this company in your area.

The principle of operation of the intercom key

The intercom is quite simple in its design.

Its package includes:

electronic board;
keyboard;
armored plate protecting internal buttons from damage;
speaker with microphone;
small display;
armored body.

The structure of the key inside is not as simple as it might seem at first glance.

Electronic power module.
Frequency emitter.

At the factory, each key is flashed, during which a laser writes a specific code into its memory, which does not change throughout its entire operation.

At the moment of contact with the intercom receiver, the identifier exchanges weak electrical impulses with the main processor. The intercom compares the key code with the existing database and determines whether it is “its own” or “someone else’s.” To open it, it is enough that the identifier was previously entered into the device’s memory.

Digital allows you to make duplicate keys. This is what the craftsmen who produce “all-terrain vehicles” use. How do they work?

Specialists take unstitched identifiers that do not have digital settings. With help special equipment they are assigned a specific code. You can enter any key value if desired. If it is familiar to the device, then the intercom will accept it as a friend and identify it as “its own”.

Thus, it is enough to “register” one key in all the intercoms in the area, and then simply make a sufficient number of duplicates that can open the entrances.

At the same time, if residents categorically do not want access to their entrances utility services, doctors, postmen, etc., they can ask installers to activate the anti-duplicate function. In this case, the intercom will be able to open the doors only with identifiers produced by the Digital company and having laser firmware.

Is it possible to get into your entrance using a key issued at work?

Because when installing security system Since all the keys are registered in the device’s memory, it is quite possible that you can register one key in the memory of two or more intercoms. Moreover, the same identifier can act as a master key for one device and be a private key for another.

Why is this so?

When determining a master key, a simple principle is used. One is selected from the general pile of identifiers, the label “not given to anyone” is attached to it, and its value is entered into a special memory cell of the processor. The intercom detects this code, recognizes it and gives access to service functions.

In the next entrance, the digital signature of the same key will be recognized as someone else’s, and it will not be possible to open the doors with it. If the identifier values are entered into the intercom, it will identify it as an ordinary one, and it can be used to open the door system.

An all-terrain vehicle that can work with several types of intercoms may exist because different manufacturers still use general systems key programming. There are not many of them, so we can assume that Digital may be suitable for other systems. However, to say that there is some kind of completely universal key, not yet necessary, because Each system operates according to its own unique algorithm.

Conclusion. What to do if you forgot your key at home?

Call home and ask them to open the door for you.
Call your neighbors and ask them to let you into the entrance.
Carry a spare set of keys with you in advance. Order them in the proper quantities so that you can have them in every bag and jacket/windbreaker.
Hide the spare key in advance in a secret place known only to you. Or better yet, several.
Call any apartment and introduce yourself as a postman or plumber. Most often you will not be refused. Only the voice must be convincing and sober.
Contact the company that installed the device and purchase another kit from them.
Use " secret codes"if they still work on your device.
Just wait until someone comes out of the entrance.
Mount the all-terrain vehicle identification “pill” into a chain and always wear it without removing it, like a talisman.

And most importantly, remain calm, think through possible force majeure in advance, and you will always have quick access to your home.

At many entrances, intercoms are now installed at the doors; they prevent unwanted characters from entering the front door: persons of no fixed abode, drug addicts and representatives of the criminal world. But at the same time, it also happens that it is difficult for the residents themselves to overcome the closed door, for some reason they are left without a key.

What is the code like?

There are times when you need to find out the code from the intercom. For example, many people have experienced a situation where the key was lost or forgotten at home. Then you have to wait for someone with your key. But you can do it differently. How to find out the code cyfral intercom?

If you have a cyfral intercom, the opening code will most likely be universal.

Each of the intercoms has built-in menus designed to encode keys, as well as assign codes to apartments and other parameters. There are also universal access codes. These codes are set identically at the factory. If you have a cyfral intercom, the opening code will most likely be universal (“1234”). It happens that the company that installed the intercom did not change this key for some reason, this code will do. This happens quite often and it even happens that the cyfral intercom code can match any other intercom of other brands and manufacturers.

Intercom Cyfral CCD 20

If you need to find out the code for the Cyfral CCD 20 intercom, you can use the password “123456” generally accepted for this design. The code used for access is the same as everywhere else (“1234”). And also the code for the table with the setting encoding “000”. It allows you to set a doorbell to a specific number. This is usually the subscriber's apartment number. You can also use it to register an electronic key code for a magnetic lock.

Intercom CCD-2094

Intercom code CCD-2094. A door with such a lock opens like this: dial “B” and “0000” and after that the door will either open or the service menu will open (the code image on the screen will change to “ON”), then you need to use the number “2” and then open door. Although the value “OFF” may be displayed, this means that the quick entry mode is turned off. The remaining passwords for controlling the intercom in this case were also changed.

In the case when universal code the cyfral intercom does not work, then you need to use the following combination: enter the numbers “0000” when the word “ON” appears, press “2”. After that, when “Cod” appears, enter the password “123400”. If this set of numbers does not work, enter the passwords “123456” or “456999”. If the password is entered correctly, the message “FO” will be displayed. In this case, you should use the combination “6” “0” “1” and then the door can be opened.

You can also register your own key in the intercom memory. To do this, you need to press the “B” key and hold it until a message appears on the display indicating that you have entered the service mode. After this, you can enter the electronic key into the intercom memory. To do this, press the “5” key and press your apartment number. The display will show “TOUCH”. Then you can apply the key.

These recommendations may not always work. A responsible company for the installation and maintenance of intercoms tries to immediately change the access codes for managing the lock settings to their own to prevent unauthorized actions with the device. But in more than half of the cases, it turns out that the installer did not change the factory settings, which makes it possible to penetrate the door with such an intercom. Usually this is done by companies that do not plan to maintain this front door in the future; they simply installed a door with an intercom and that’s it.
