    Hello, I am renting a flat, but the owners do not know what the code to the cage is, and they do not care too much about the fact that the intercom does not work for me. I took a picture of the intercom, my number is 7.

    Mostly, such installations are maintained by companies (if it is, for example: a cooperative) report to the administration and they will repair it and you will get a code.

    Advice - ask the neighbor, facility administration who installed, maintains or repairs the intercom in this cage. Contact with him is inevitable.
    The code for the apartment results from what the installer initially entered from the code table or at his discretion or the tenant's suggestions.

    And do you know if when I contact the cooperative, it will be enough for them to rent a piece of paper, or will the owner of the apartment be needed here?

    Should be the consent of the owner, this is a rule.

    You have an old Laskomex, so I assume you also have a Laskomex system - you have to ask the system administrator for the codes - they will either give you from the original table, or the maintenance man can give you a new one through programming. And if they do not, they have to write to us to the service mailbox with the company and administrator number (something a'la "serial number" of the system) - and then we will be able to generate and issue the original table of codes.

    You can also try your luck and see if you can enter the user menu and change the code yourself (this can be done without knowing the old code, provided that you do not need to enter the current code to "log in". The factory setting does not require entering the old code ) - instructions on this topic: https://www.elektroda.pl/rtvforum/topic1797216.html#18386951

    It depends on the people working there, but the rental paper should be enough.

    PS. Do you know if the combination lock is active at all? Try to choose your number. apartment, [KEY], and enter some 4 numbers. If it shows you ERR it is active, if OFF it is disabled. Cooperatives often turn off, because the codes spread much faster and easier around the estate than "pills".

    Yes, but not really - the code table is "loaded" from the box and even if nobody has entered and used anything, the codes are still there and knowing them you can unlock the lock. Therefore, if you do not use a combination lock, I recommend disabling it in the configuration.

    PS. My colleague, who had a similar problem, as the author of the topic even calculated, that out of 10,000 combinations he can "brute-force" 30 consecutive combinations a day, starting with 0000, 0001, 0002 etc. and it will take him up to a year to find the right cipher . And probably on the 3rd or 4th day he "hit" his combination :D

    Strange, when replying I highlighted these words and clicked "selective quote": / maybe I made a mistake while writing or editing later? Either way - it's true, these quotes were not properly signed. Sorry about that, I didn't even notice. I have already corrected.

    .
    I think it's about the function of the code lock codes entered by the resident, to clarify the phrase. Because, by opening with a key ring, it can also be referred to as a combination lock. This key fob has a numerical code stored in it (it is stamped on the plastic), admittedly in a different sense than the one entered with the keypad, but nevertheless. Here is my question: is it possible to identify the flat to which it is assigned by the code number on the key fob, is its use registered in the system and can the fact of its use be confirmed later (I mean criminal, hostile events). Or, even though the key fobs have different radio system codes, within a single staircase, are they not differentiated in the system into individual flats?

    If the system is well maintained in the service, then yes. If it is a mess and the key fobs are programmed anywhere as long as they work, then no more.

    .

    Some systems have this others do not. Are you asking about a specific system or in general terms?

    See answer above.

    I'm talking about the Aco system - are there such possibilities in this system and is it a good system at all?

    ACO is a good, Polish system.
    What specific capabilities are you asking about? Archiving of events?

    Yes, that's exactly what I had in mind - archiving both the codes you enter and then assigning them to a particular flat (if that's possible, because it's possible to change these codes yourself - I don't know for sure with Aco, but with other systems I know it's possible), as well as the key fobs, which are, after all, numbered, and this radio system code can be read from them with the appropriate reader.

    ACO does not have this capability, although they have been expanding a bit recently and have started working with Roger in the RFID field,
    where there is full archiving (RACS 5): https://www.aco.com.pl/produkty/inspiro-6-wid...kiem-szyfrowym-czytnikiem-zblizeniowym-roger/ well but it's such a prosthesis because it's completely not applicable to codes.

    The classic Laskomex block systems - CD-2502, CD-3100 and CD-2600 - do not have this capability. When an assigned key is applied, the number in the memory under which the key is stored is displayed - this is the only way to identify the key in question from the panel. A little more can be done with the ISD interface.

    Event logging has the CD-4000 monoblock (and our new 2-WIRE BASTION GEMINI set, but this is a video set for an individual customer).

    But the birds are singing that there is something out there.... There are ideas, there are prospects. Not tomorrow, not next year, but our eggheads are working on things....

Topic summary

✨ The discussion revolves around a malfunctioning intercom system in a rented flat, specifically model #7, where the user lacks the access code. Responses suggest contacting the facility administration or cooperative responsible for the intercom's maintenance to obtain the code. It is noted that the intercom is likely a Laskomex system, and the user may need the owner's consent to access the necessary information. Additionally, there are suggestions to check if the user can access the intercom's user menu to change the code independently, provided the factory settings allow it.

FAQ

TL;DR: Renting and intercom dead? 4‑digit keypads mean 10,000 combos, but "The rental paper should be enough." Contact the administrator for codes or service, check keypad status (ERR/OFF), or disable codes if unused. [Elektroda, Serwis_LX, post #18399733]

Why it matters: This FAQ helps tenants, owners, and admins quickly restore secure entry without guesswork.

Quick Facts

How do I get my door code if I’m renting and the intercom doesn’t work?

Contact the building administrator or maintenance company. They can read the original code table or reprogram a new code. “The rental paper should be enough,” though policies vary. You can also check if the keypad is active first. [Elektroda, Serwis_LX, post #18399733]

Do I need the owner’s consent to fix or change intercom settings?

Yes. Building access systems typically require owner authorization before codes are issued or programming changes occur. Administrations follow this rule for liability reasons. [Elektroda, ROWE, post #18399560]

How do I check if the keypad code function is enabled?

Use this 3‑step test:
  1. Enter your flat number.
  2. Press the KEY button.
  3. Enter any four digits; ERR means enabled, OFF means disabled. [Elektroda, Serwis_LX, post #18399733]

Can I change my entry code without knowing the old one?

Often yes. Many Laskomex units allow entering a user menu and setting a new code without the old code if factory defaults remain. Follow local instructions or ask the administrator. [Elektroda, Serwis_LX, post #18399733]

Is brute‑forcing a 4‑digit door code realistic?

There are 10,000 combinations. One user tried about 30 per day and hit the code within four days. However, this fails if the keypad feature is OFF. Disable codes you don’t use. [Elektroda, Serwis_LX, post #18399733]

Who maintains intercom systems in cooperatives or condos?

Administration typically outsources maintenance to a service company. Report faults to the cooperative’s office; they handle repairs and can provide codes. [Elektroda, karolark, post #18399048]

What if the administrator won’t share or doesn’t know the code?

They can request the original code table from the manufacturer’s service using the system’s company/administrator number. Maintenance can also program a new code. [Elektroda, Serwis_LX, post #18399733]

Can my RFID key fob be traced to a specific flat?

It depends on configuration and record‑keeping. Properly maintained systems map fobs to flats. Poorly maintained ones do not. Some systems log uses; others don’t. [Elektroda, Ircys, post #21723393]

Does ACO support event logging and fob assignment per flat?

Classic ACO doorphone lacks full event archiving for keypad codes. ACO’s cooperation with Roger enables RFID logging in RACS 5, but that doesn’t cover keypad code events. [Elektroda, Ircys, post #21723628]

Do Laskomex systems record entry events?

CD‑2502, CD‑3100, and CD‑2600 do not log events. The CD‑4000 monoblock adds event logging. Newer 2‑WIRE BASTION GEMINI video sets log events for individual customers. [Elektroda, Serwis_LX, post #21725665]

What is the “company and administrator number” the service needs?

It’s like a system serial identifier for the staircase installation. With it, the manufacturer can generate and issue the original code table to authorized parties. [Elektroda, Serwis_LX, post #18399733]

Will my rental agreement alone be accepted to obtain codes?

Often yes. Administrations may accept a rental agreement to verify your right to access. “The rental paper should be enough,” subject to local policy. [Elektroda, Serwis_LX, post #18399733]

Should I disable keypad codes if I only use RFID fobs?

Yes. If residents use fobs, administrators often disable keypad codes to reduce code sharing and increase security. Ask for this in configuration. [Elektroda, Serwis_LX, post #18399733]

What is a monoblock like the Laskomex CD‑4000?

A monoblock integrates the door panel and controller in one unit. The CD‑4000 adds event logging versus older distributed models. Useful for audits. [Elektroda, Serwis_LX, post #21725665]
