DoorBuzzin shut down. Here's how to get your buzzer working again.

DoorBuzzin worked by giving your unit a phone number and having your building's entry panel call it. That number has stopped answering, so the panel rings into nothing. Nothing is wrong with the panel or your phone.

DoorBuzzin's notice asks residents to have their door-entry system call a different number, and says all DoorBuzzin user information will be permanently deleted by October 14, 2026. Your old access codes and rules can't be exported, so write down which guests and couriers had codes while you still remember.

Ask your property manager to change your directory entry to your own mobile number. It costs nothing and gets your buzzer ringing again, usually within a day. If one phone answering is all you need, stop there.

What you lose is everything DoorBuzzin added: only one phone rings, there are no codes for guests, and nobody gets in while you're asleep, in a meeting or away. If you relied on any of that, you'll want a replacement app, and since you're emailing your property manager anyway, it's the same single change.

Enterkey does the same job DoorBuzzin did: your buzzer calls an Enterkey number, and you decide what happens next. Answer and buzz people in from anywhere, or let Enterkey answer and open the door for you.

DoorBuzzin Pro covered offices, short-term rentals and realtors. Enterkey works for them too: PINs with keys that switch off on their own for guests and clients, schedules for office hours, and a team invite so staff all get the buzz.

Front desks can run the buzzer from a computer at enterkey.app/login, so not every staff member needs an iPhone. The account itself is created once in the iPhone app. See small business clients, therapists and home office practitioners and short-term rental hosts.
