Telephone entry not dialing? We repair any entry system: DoorKing, Linear, Mircom.
A dead keypad, calls that never reach the apartment, an outdated directory, or a door that will not release after the tenant presses the key. We repair every piece of the chain, from the phone line to the strike.
The visitor enters the code and nothing happens. No call reaches the tenant. The phone line, dial tone detection on the panel, or the main board.
Will not dial out at all
The visitor enters the code and nothing happens. No call reaches the tenant. The phone line, dial tone detection on the panel, or the main board.
Calls the wrong apartment
The visitor dials 4B and the phone in 2A rings. The directory programming drifted, or a tenant number changed in the panel but not everywhere. We re-sync it to the real tenant list.
Door will not release on 9
The tenant hears the visitor and presses the release key, and nothing happens at the door. The panel's strike output or its release key setting, or the strike itself.
Keypad stuck or dead keys
Some keys do not register, or the keypad is stuck. Weather, wear or damage. We repair or replace the keypad, and the rest of the panel is almost always fine.
Phone line being retired
Your carrier says the copper phone line feeding the panel is going away, and the panel depends on it. We convert the panel to cellular so it keeps working without the copper line.
Display dead or garbled
The screen is dark, shows garbled characters, or only the backlight. The display board failed, or the panel is browning out. A display board or a keypad swap.
The six common culprits, in the order we check them.
We test the line first, then the panel, then the directory, then the door.
Phone line problem or retirement
Carriers are retiring copper phone lines across NYC. If your panel still runs on one, line wear, carrier changes or removal of the line will take the system down. We convert to cellular, or add a cellular backup to a working panel.
Dial tone detection failure
The panel cannot detect dial tone when it picks up. Common after a carrier upgrade changed the line voltage, or when other equipment shares the line. Diagnosable on site.
Main board failure
The panel's main board failed: no dial, no response, dead keypad. A matched board for current panels, and reconditioned stock for many discontinued ones.
Keypad wear
Outdoor keypads take thousands of presses in all weather. Keys stick, contacts corrode, and some stop registering. The keypad is replaced as a unit, and the rest of the panel is unaffected.
Directory programming drift
Years of tenant turnover without panel updates, and the directory maps the wrong names to the wrong codes. We re-sync it to the real tenant list and update the paper or electronic directory.
Strike output or strike failure
The tenant presses the release key, and the door does not open. The panel's strike output failed, or the lock hardware did. We handle both in the same visit.
Your carrier is retiring the phone line?
Telephone entry panels dial out over a copper phone line, and carriers are retiring them. We add a cellular backup to a working panel, or convert it to cellular, so the entrance keeps working.
You do not need the original installer.
We work on the common telephone entry panels across NYC, including older models from vendors no longer around. We identify the panel, source parts or compatible substitutes, and get it dialing again.
The telephone entry panels we service
Dial-based entry systems across NYC, plus older unbranded panels in pre-war buildings. If it has a keypad and dials a phone, we have probably been inside one.
The line and the door
The phone line or cellular link that carries the call, and the strike that opens when the tenant presses the key. We work on all of it in one visit.
Repair first. Convert when the phone line is the problem.
When we repair
Most telephone entry calls are a repair: a keypad, a board, a directory update, a strike. Targeted fixes that keep your existing panel.
When we convert or replace
Your carrier is retiring the line feeding the panel, the panel is a dead model with no parts, or you were already planning a phone-based entry system. Then the money is better spent on the conversion or the new system.

Four steps, and every tenant is dialed before we leave.
Phone triage
Will not dial, wrong apartment rings, door will not release, keypad dead, or a line notice. Five minutes tells us which parts to put on the truck.
On-site diagnostic
The line first, then the panel, then the directory, then the strike. The first 20 minutes finds the failure.
Fix, or part on order
Keypads, boards for popular DoorKing and Linear models, and strikes are same-visit. Cellular conversions are a scheduled follow-up once the right module is ordered.
Test every tenant
The visitor dials, the right tenant rings, audio works, the release key opens the door. Written summary, and the new backend documented if we converted to cellular.
