Asking your property manager
To make your apartment buzzer call a new phone number, you ask your property manager to change one field: the phone number stored against your unit in the entry system's directory. Nothing is rewired and nothing is installed at the door. Below is exactly what to ask for, a short request you can copy into an email, what the change looks like on the manager's side for the common panel brands, and how to test it once it is done.
What exactly are you asking for?
Telephone entry panels keep a directory: a list that maps each unit, or each buzz code, to a phone number. When a visitor selects your unit, the panel dials whatever number is in that slot. Your request is to replace the number in your slot with a new one, either your own cell or an Enterkey virtual number.
That is a routine edit for the person who manages the entry system, usually made in the software or web portal they already use, or on the panel's own keypad. It does not change anyone else's entry, and it can be changed back at any time. If you want the wider picture first, the apartment buzzer guide explains how the directory and the unlock tone fit together.
A request you can copy
Keep it short and specific. Managers get vague "my buzzer is broken" emails all week; a request that names the unit, the field and the new number usually gets done in one pass. Copy this and fill in the brackets:
Subject: Buzzer directory update for unit [unit number]
Hi [name], could you please update the phone number on the entry system directory for unit [unit number] ([your name], buzz code [code if you know it]) to [new number]?
Nothing else needs to change: same unit, same code, only the number it dials. I will test it from the panel once it is updated. Thank you!
What does the change look like on their side?
The steps depend on the panel, but the field is the same idea everywhere: the resident's phone number in the directory. On Mircom telephone entry panels and on Linear telephone entry systems, each directory entry stores a number to dial. Most Enterphone panels in older Canadian buildings work the same way, as do dial-out TekTone systems and most apartment call boxes, including gate pedestals.
If your manager uses a service company for the entry system, they may pass the request along, which can add a few days. It helps to mention that only the number changes, not the unit or the code.
What if they say no, or aren't sure?
Ask one follow-up question: "Can the directory entry for my unit point at any phone number?" If the answer is yes, the change is possible and the hesitation is usually about who does the work, so offer to send the number in writing. If your buzzer only rings a wired handset inside your unit, there is no outside number to change, and no app, Enterkey included, can take that call.
Some managers ask why. A plain answer works: you want the buzzer to reach you when you are not home, or you want deliveries and guests let in without giving out your personal number. Enterkey is set up by the resident, costs the building nothing, and changes nothing for other units.
After the change: test it
Go down to the panel, select your own unit, and confirm the new number rings. If you pointed the entry at Enterkey, test twice: once with a timed key active, so the door should open on its own, and once without, so the call should reach your phone. The how it works page shows the screens you will see in the app.
If nothing rings, the usual cause is a typo in the new number or a change that was saved to the wrong unit. The checklist in apartment buzzer not working: fixes covers the rest, and support@enterkey.app answers within hours.
