Door Buzzer Repair, Replacement and Upgrades

The street panel, the apartment buzzers, the door release and the wiring between them. We handle all of it.

Door Buzzer Repair

Apartments not ringing, no audio, or a dead panel. We trace the fault, whether it is a failed call button, corroded wiring, a blown transformer or a bad board, and fix it on site.

Door Release and Electric Strike Repair

Tenants press the button and nothing happens at the door. We repair or replace the electric strike, the relay and the release wiring, and adjust the door so it actually latches.

Apartment Buzzer System Replacement

When the old panel is beyond repair or parts are no longer made, we install a new buzzer entry system and reconnect every apartment. Brands we install include Comelit, Aiphone, 2N, Alpha Communications and DoorKing.

Upgrade to Video and Phone App Entry

Swap a button-and-speaker panel for a video intercom so tenants see who is at the door, and can answer and buzz people in from their phone. We check on the site visit whether the new system can run on your existing wiring.

Buzzer Not Working? Find the Cause.

Most buzzer failures come down to a few parts. We confirm the cause on site before any work starts.

No apartment rings at all
Failed power supply or transformer, a blown fuse, or a dead board in the street panel.
Only one apartment doesn't ring
A broken apartment station or a break in the wire to that unit. The rest of the system is usually fine.
It rings, but the door won't unlock
The electric strike, the door release relay or the release wiring. Often the strike is misaligned or the door doesn't close fully.
No audio, or a loud hum
An audio board fault, corroded connections, or wiring damaged by water.
Works in dry weather, fails when it rains
Moisture inside the street panel or in outdoor wiring.
Stopped working after renovation
Wiring cut or disconnected during construction. Usually reconnected and tested in one visit.

A Working Buzzer Is Required by Law.

In most NYC apartment buildings, a broken buzzer can lead to an HPD violation. Here is what owners need to know.

When a Buzzer System Is Required

Under NY Multiple Dwelling Law §50-a, apartment buildings built or converted after January 1, 1968 need self-closing, self-locking entrance doors. Buildings with eight or more apartments must also have an intercom at the main entrance that lets each apartment talk to the visitor and release the door. In older buildings, the owner must install one when a majority of tenants request it in writing.

Who Has to Fix a Broken Buzzer

The building owner. Tenants can report a broken buzzer or intercom to 311, and HPD can inspect and issue a violation that the owner has to correct. Under the Multiple Dwelling Law, failing to install or maintain a required intercom is a misdemeanor.

For Landlords, Supers and Boards

We find the actual fault, give you a clear written quote before any work, and leave the system tested and working so the building is back in compliance. We work directly with managing agents and co-op and condo boards.

For Tenants

If your buzzer is broken, tell your landlord or managing agent first, since the repair is the owner's responsibility. They can call us at (917) 565-0579 and we'll schedule the repair.

Door Buzzer System FAQ

How much does buzzer repair cost in NYC?

It depends on what failed and how many apartments are on the system. Replacing one bad part costs far less than a new panel. We diagnose on site and give you a written quote before any work starts, so there are no surprises on the bill.

My buzzer rings but the door won't open. What's wrong?

The intercom side is working, so the fault is at the door: a worn or misaligned electric strike, a failed release relay, damaged release wiring, or a door that no longer closes far enough to latch. We fix the hardware and adjust the door so it releases every time.

Can you replace an old buzzer system without rewiring the building?

Often, yes. Many current buzzer and video intercom systems are built to run on existing building wiring. We test the wiring on the site visit and tell you if any runs need replacing before you commit.

Who is responsible for fixing a broken buzzer, the landlord or the tenant?

The landlord or building owner. Tenants should report the problem to the landlord first. If it isn't fixed, they can file a complaint with 311, and HPD can inspect and issue a violation.

How fast can you fix my buzzer?

Same-day service is available, and most repairs are finished in a single visit because we carry common parts for the major brands on the truck. Call (917) 565-0579 and we'll book the fastest available time.

Can you upgrade our buzzer to video or a phone app?

Yes. We upgrade audio buzzer panels to video intercoms with mobile app access, so tenants see visitors before they open the door and can let them in from anywhere.

Do you work with co-op boards and managing agents?

Yes. Much of our buzzer and intercom work is for co-ops, condos and managed rental buildings. We explain the options to the board, put the quote in writing, and keep the managing agent updated through the job.
