Can my building refuse to change the number my buzzer dials?

Usually not for a basic change. The programmed number is just a directory entry, and most management companies will update it on request, sometimes for a small reprogramming fee on older panels that need a contractor visit. They can refuse to install hardware or rewire, but swapping the dialed number is routine. If they stall, ask in writing and reference your lease's quiet-enjoyment or access terms.

Is it safe to put my cell number in the building's buzzer directory?

It works, but anyone at the door dials it, and it can show up on printed lobby directories or get shared between tenants over the years. If that bothers you, use a virtual number you can change or revoke later instead of your real one. There is no security downside to the building knowing the number; the concern is purely privacy and spam.

How to Forward Your Apartment Buzzer to Your Phone

By Ty · 2026-03-16

You searched for how to “forward” your buzzer to your cell, expected a toggle somewhere, and found nothing. That is because there is nothing to forward. Your lobby panel is not connected to your phone at all. When someone enters your unit number, the panel makes a real outbound phone call to the number your building has on file for you.

If you want that call to ring your cell, the lever is on the building side, not your phone. And even when the call reaches you, you are still tied to your phone to answer and press a key every single time someone shows up.

How to fix it

There are a few ways to get a buzzer call to reach you on your cell. They trade off privacy, effort, and whether your visitor still needs you to answer live.

Option	Pros	Cons
Give the building your cell number	Free, rings you directly	Number ends up in the lobby directory; you answer manually every time
Use a Google Voice number	Free, keeps your real number private	You still answer manually and press a key each time
Ask about a lobby door code	No phone call needed once visitors have it	Many buildings ban sharing it; a static code never expires
Lowkey	Answers for you, passcodes and schedules, private number	Quick one-time setup with your building

If your buzzer is failing rather than just inconvenient, the apartment buzzer not working guide has the full diagnostic.

Where Lowkey helps

Lowkey is the cleanest way to make your buzzer ring your phone and then do the work for you. It is software with nothing to install and no hardware on the wall, so you skip the camera kits and panel swaps entirely. You hand your building a virtual number to program for your unit, and from then on the panel’s call reaches the app instead of your raw cell.

From there you are in control. Answer the call from anywhere and open the building’s front door so your visitor can come up to your unit, or skip answering entirely: hand out a 4-digit passcode for the keypad, set a recurring schedule that auto-buzzes people in and auto-expires, or share access with roommates and multiple phones. Activity history shows you exactly who got in and when, and push notifications keep you posted in real time. It runs on 99.99% uptime, and the 14-day free trial lets you try it on your own panel first.
