    Hello!

    As in the topic - how to add a key fob to Laskomex CD 2502 without knowing the installer code? Because apparently it`s possible... Unfortunately, the administration ignored me because they didn`t plan it and the previous administration didn`t leave it to them. I can`t find the switchboard either because the intercom is in an unusual place and the neighbors don`t know where it could be... someone/something?

    On pages 43 and 44 of the CD 2502 manual there is information on how to do this. There is one condition. Is this function blocked by the service technician?

    To enter the user menu you should (using the help of another person):

    » Call the premises from the panel
    » Answer the call at the premises
    » The person at the panel must hold the "key" ( but only after answering the call ) when the tenant simultaneously presses the latch release button 5 times ("OPC" will appear on the panel for a moment along with 3 short beeps in the loudspeaker)
    » End the call
    » Select the given premises again, press the key and: depending on the system settings, enter the entry code (CHA parameter=1) or not (factory setting)

    The bold part is important here - if you hold your finger on the buttons too early (before establishing the connection) or for too long, an "E" error may occur (beams blocked).


    Something like e.g. [0G7] will appear on the panel display.

    The first parameter from the left is the bell melody - there are 9 of them - we change it with the number [1]
    The second one is the way of calling. The available options are: [Loud, [S]ilent, [S]moderate, [S]creasing]. We change [2] angle.
    Third - number of bell repetitions from 1 to 9 - change with [3] key.

    Numbers:
    [0] - Allows you to change the input code (if not locked)
    [8] - Allows you to add an electronic key (if not blocked)

    This may not always be possible either. Of course, this can be done in our systems and everything is unlocked by default, but the installer has the option of blocking both the addition of chips and the change of the code by tenants (separate parameters "CEd" and "idA" in the control panel program). In such a case, you must contact the facility`s administrator, which, unfortunately, usually involves additional fees.
    It is also worth noting that in order to add a keypad to a multi-entry system (master-slave or HU), the procedure must be performed from both the slave and the master panel (e.g. from the cage and from the fence), because in order to protect installers against accidental deletion of keys, it was decided that they will be recorded and stored in other memory areas of the U and H control panels.

    Thanks for your response :)
    I already tried to add from the user menu and the `add` message was even displayed, but when I placed the key fob, nothing happened... :( so the frequency was 125Mhz

    Have you really tried to program a good key fob?
    Two types of keys are used in Laskomex CD-2502 intercoms:
    1. iButton touch keys (formerly Dallas) for the panel with the letter T, e.g. CP-2502TK
    2. proximity RFID readers. for the panel with the letter R, e.g. CP-2502NR

    I have these: RFID UNIQUE 125kHz T5577
    in the sense of keys :) So I have to check what intercom I have...

    The RFID keychain is usually read near the keyboard, and iButton keys (Dallas) have an appropriate socket on the panel housing to which the key plugs.

    You added a photo and you can see the nest there. Buy iButton key (Dallas).

    So I have this ibutton? And don`t they also work at 125 kHz? Sorry for asking, but I don`t know much about it...

    The iButton key (Dallas) has a ROM chip with an individual 64-bit number and therefore must be touched to this socket on the panel (to power this chip).

    Hmm, yes, unique also works on this principle, I mean the magnetic field that powers this keychain... do I understand correctly?

    Search Google for how iButton and RFID keys work, because I won`t go into detail here. You need an iButton and try to program one. Gain further knowledge on your own. Sorry.

    Unique key fobs do not fit this reader. Here you need a touch key (not proximity!) iButton.

    RFID, i.e. proximity key rings/cards, have a plastic casing and work on the principle that you just need to bring them CLOSE to the reader. The key fob/proximity card is powered and communicated with without contact using a variable magnetic field from the reader.

    iButtons, called Dallas lozenges, resemble a large watch battery, their casing is metal, which is also the contacts for power and communication. To activate, they require CONTACT with the reader in an appropriate way. Power supply and communication with the key fob occurs through the flow of electric current between the reader and the key fob.

    It looks like this panel DOES NOT have an RFID reader. There used to be hybrid panels with both Dallas and RFID, but we have not sold them for at least 2 years.

    Hello and welcome. Today I tried to save electronic keys based on your instructions. I entered the menu normally. I changed the ringtone volume and melody. Everything works. When trying to assign the iButton, I press button 8 - the ADD message appears - I place the iButton against the reader. Unfortunately, I do not receive any other message later (the manual states that the word NEU should appear). I applied the tablet for a dozen or so seconds. Maybe too short? Pressing 8 twice shows the inscription SCN (scan?), I also placed the tablet then but nothing changed.

    Does the key applied to the reader in the standby state cause any reaction from the control panel?
    It is also possible that there is a lock on key programming by users (P-2, idA=0).

    There is no reaction. I thought that if I entered the key addition menu without the ERROR word appearing, it would be possible to add a key normally. I will try again (I will clean the reader on the intercom because maybe it is dirty?) Thank you for your interest in the topic. Regards.

    I don't have. But the key-entry system definitely works because other people in the cage use it.

    I have such an intercom. Laskomex cd-2502.

    Adding a key fob to the Laskomex CD 2502 intercom without the installer code Adding a key fob to the Laskomex CD 2502 intercom without the installer code

    and these tablets were bought new, 4 pcs on a popular website on AL... I checked all 4 by touching the round reader to the ADD code - after about 30 sec the SCN message appears and then everything disappears and returns to the starting point.

    from the item description: Electronic Keys, IButtons DALLAS - "iButton S0990". Compatible with most DALLAS readers and system standards on the market used in combination locks, intercoms and video intercoms equipped with a DALLAS reader. Each lozenge has its own unique code printed on it, which can be entered into the memory of any Dallas system reader.

    Maybe I’m doing something wrong or the ability to add keys is blocked.

    And that`s where we should have started, rather than writing under other posts.

    As Col. Gkwiatkowski rightly pointed out: you have the wrong keys - you need RFID.

    To conclude the topic, perhaps for future generations I will mention how to check whether the reader in the panel is receiving power.
    You should lock the processor by holding down the RESET button on the electronics cassette - and measure the DC voltage on the reader with a multimeter - put one probe to the middle part of the reader, the other to the outer ring. A properly functioning reader will have 2.8V - 3V.

    At the moment of writing, it is best to buy keys from us - there is generally no problem with these - I also know that work is being carried out to improve the operation of the reader (RFID and DALLAS) and in future releases of the EC software there will be changes to improve compatibility with other keys - concern this is especially true for programmable RFID keys.

    I want to program RFID key fobs in a friend`s block and when I put the key fobs to the keyboard, nothing happens.
    I will add that my key fobs don`t work and when I press 4x9 it displays: 2502 U68H, but my friend`s case doesn`t work when I press 4x9 it displays: 2502 U68A.
    Is it the fault of the program version or the lack of a reader that does not see the key fobs?

    Missing / not connected / software disabled / faulty / wrong type of key / damaged key / applied in the wrong place... go with your friend to the administrator of this facility and ask. Not every panel needs to have a reader, and not every administrator needs to want users to add keys themselves.

    Added after 3 [minutes]:

    If the panel has a TM reader (Dallas), it cannot be unnoticed - which does not mean that it is functional and turned on; RFID, on the other hand, cannot tell the difference from the outside. If tapping the key does not give any response, there is a good chance that the panel does not have RFID.

Topic summary

The discussion revolves around adding a key fob to the Laskomex CD 2502 intercom without the installer code. Users explore the possibility of programming key fobs, specifically distinguishing between iButton (Dallas) and RFID (proximity) keys. It is noted that the intercom may have restrictions on user programming, and the correct type of key is crucial for successful addition. Users share troubleshooting steps, including checking the reader's functionality and ensuring the correct key type is used. Ultimately, it is confirmed that RFID keys are required for the intercom in question, and users are advised to consult the manual for specific programming instructions.
