Apartment buzzer not working: find the fault by what you see in the lobby
An apartment buzzer that is not working usually fails in one of five ways: no phone rings at all, it rings but lands in voicemail, the call connects with no sound, the door digit does nothing, or the panel itself is dead. Each points to a different cause and a different person to fix it. BuzzMeBro rings every phone in the apartment at once, so one filtered phone is no longer a locked door.
Someone is in the lobby and you are not getting in, or they are not getting up to you. The word broken covers five different faults, and each has a different fix.
This page sorts them by what you can actually see or hear. Find your symptom, read the likely cause, then follow the link to the full guide for it. It works the same way for a Toronto tower, a Vancouver walk-up with an Enterphone, or anything in between.
How a working buzzer is supposed to behave
Most lobby panels are a phone that dials out. A visitor enters your unit code, the panel calls the one number stored for your unit, and you answer like any other call.
When you press the door digit, a touch tone travels back down the call. The panel hears it and releases the lock for a few seconds. What pressing 9 actually does.
Every fault below is one link in that chain breaking: the stored number, the call reaching a phone, the audio, the tone, or the panel and door hardware.
Which symptom matches yours?
| What happens | Most likely cause | Who fixes it |
|---|---|---|
| Nobody in the apartment gets a call | Wrong, old or non-local number stored in the panel | Landlord or property manager changes the entry; you supply a number that works |
| It rings but goes to voicemail, or your phone stays silent | Spam filtering or an unknown-caller setting on the phone | You, in your phone settings or carrier account |
| You answer but hear nothing, or they cannot hear you | Panel speaker or microphone fault, or the call path on your end | You test your phone first; a panel fault goes to the landlord |
| You press the digit and the door stays locked | Wrong digit, pressed too early, tone lost on the way, or a lock fault | You first; a lock or release fault goes to the landlord |
| The panel is dark, frozen or shows an error | Power, the panel phone line, or the hardware itself | Landlord or property manager |
1. Nothing reaches any phone
If not one phone in the apartment rings, the panel is almost always dialling the wrong thing. Common versions are a previous tenant number that was never removed, a number from another area code region that the panel line will not call, or a number with a typo. The visitor often hears a recording or a disconnected message, which is the giveaway.
Many panel lines only dial local numbers, so a number that works from your own phone can still be unreachable from the lobby. Start by finding out what number your buzzer calls, then check it is local to the building with the buzzer number check.
- Visitor hears a disconnected message: your buzzer is dialling a number that no longer exists.
- Visitor hears that the call cannot be completed: what that recording means.

2. It rings, but goes to voicemail or your phone stays silent
This one is good news in disguise. The panel dialled the right number and your carrier received the call. Something between your carrier and your ears stopped it ringing.
The usual culprit is spam filtering. A lobby panel calls many numbers briefly from a line nobody calls back, which looks like a robocaller to carrier filters. On an iPhone, Screen Unknown Callers set to Silence sends any number not in your contacts straight to voicemail. Saving the lobby number as a contact is the first thing to try.

3. You answer, but hear nothing or they cannot hear you
Start on your side, because it is quick. Check the call did not route to earbuds or a car, and if you take calls over Wi-Fi calling, switch it off and have someone buzz again. Calls delivered over home internet can behave differently from calls over the mobile network. Wi-Fi calling and your intercom.
If the audio fails on every phone in the apartment, the panel speaker or microphone is the likely fault. That is building equipment. Report it with the make printed on the faceplate, which helps the technician. How to identify your intercom.
4. You press the digit and the door does not open
The most common reason is simply the wrong digit. Nine is a common default, but the building sets the digit and some use a different one. The next causes are pressing it before the panel is listening, and a call path that distorts the touch tone so the panel never recognises it. If the panel accepts the tone and hangs up but the lock does not release, the door hardware is at fault.
Ask the building which digit your panel uses, then test it once while someone stands at the door. You pressed 9 and the door did not open walks through each cause.
5. The panel itself is dead or shows an error
A dark screen, a frozen display, an error message, or a panel that will not take a code at all is a fault in the building system. Power, the phone line feeding the panel, or the unit itself can be the cause. Nothing on your phone will change it.
Note the time, what the screen shows, and whether neighbours have the same problem, then report it in writing. One email covering the whole building gets acted on faster than ten verbal mentions in the elevator.
Who is responsible for fixing it?
In Ontario, the Landlord and Tenant Board says a landlord must keep a rental property in a good state of repair, and that things the landlord provides must be kept in working order. It also says the first step is to ask the landlord, in writing, to fix the problem, and to keep a copy. Is your Toronto landlord responsible for the buzzer?
In British Columbia, the provincial government says landlords are responsible for most repairs to a rental unit and that tenants must request repairs in writing, by email, letter or text message. In a strata building, some repairs are the strata responsibility, so your landlord should tell you how to report those. Vancouver apartment buzzers.
Changing which number your unit dials is a different request from a repair, and usually a routine one. Get a ready-to-send message for your building manager. None of this is legal advice.
Stop one phone from being the only way in
Faults 1 and 2 share a root. The panel stores one number per unit, so the whole apartment depends on one phone, one carrier and one set of filter settings. When that phone is silenced, in a meeting or out of battery, the door stays shut for everyone.
If you live alone and your buzzer only needs to ring your own phone, saving the lobby number as a contact may be all you need. If you share the apartment, BuzzMeBro gives it its own local number for the building to store. A buzz then rings up to 4 phones at the same time, whoever answers presses the door digit, and one filtered phone stops mattering. Get your number, or see every buzzer problem guide.
Questions people ask
Why did my apartment buzzer suddenly stop working?
The most common sudden change is on the phone side: a spam filter update, or a setting that silences unknown callers. If every phone in the apartment stopped at once, the stored number or the panel changed instead, and the building needs to check it.
How do I tell if the problem is my phone or the buzzer?
Stand in the lobby and buzz your own unit. If your phone rings and the door opens, the system works and the problem is when or where you keep your phone. If it does not ring, ask the visitor what they heard, then match it to the table above.
Who pays to fix a broken apartment intercom?
Building equipment such as the panel, its line and the door release is generally the landlord to maintain. Ontario and BC both tell tenants to request repairs in writing and keep a copy. Settings on your own phone are yours to change.
Can my landlord make the buzzer ring more than one phone?
Usually not, because the panel stores one number per unit. Some panels have a second number that only rings after the first one rings out. BuzzMeBro gives the apartment one local number that rings every registered phone at once, so the landlord only stores a single number.
