Intercom works, door stays locked
Prioritize release button, relay, release wiring, power, electric strike/maglock and door alignment.

Electric Strike & Door Release Repair in New York City
If the buzzer rings, the visitor and resident can hear each other, but the entrance will not unlock, the problem may be in the release path rather than the communication path. Unlimited Applications Security Company troubleshoots relays, power supplies, wiring, electric strikes, magnetic locks, access-control interfaces and physical door alignment across New York City.

The Door-Release Path: Test Every Link Before Replacing the Intercom
- Release button / credential
The command starts at an apartment station, access-control reader, keypad or exit device. - Controller / relay
The system must produce the correct output and switch the release circuit reliably. - Power supply / wiring
Correct voltage must reach the lock through stable low-voltage wiring and connections. - Strike / maglock / door
The locking hardware must operate electrically and the door/latch must be mechanically aligned.

Common Symptoms and What They Point To
Strike buzzes but does not release
Check voltage, latch pressure, worn strike components, frame alignment and whether the door is binding.
Reader accepts card, door stays locked
The credential path may be working while controller output, relay, lock power or the locking device has failed.
Property Types and Door Conditions Matter
Apartment Buildings
Main entrances, vestibules, package areas and multi-tenant intercom releases.
Brownstones & Small Multifamily
Older frames, compact vestibules, legacy buzzers and limited wiring paths.
Stores & Offices
Glass or metal storefront doors, staff entrances, keypads, readers and electric hardware.
Managed Properties
Co-ops, condominiums and mixed-use buildings where intercom, cameras and access control share the entrance.
Manufacturer and Model Details Narrow the Repair, but Testing Comes First
Equipment associated with Adams Rite, HES, Trine Access Technology and ASSA ABLOY may be serviceable depending on the exact model, voltage, door preparation, wiring, condition and parts availability. The manufacturer name alone does not prove compatibility or determine the repair.
Useful information before a site visit: photograph the strike or maglock label if accessible, the intercom/access-control panel, the affected door and frame, and describe whether the lock makes a sound, releases intermittently or remains inactive.
How Door Release Connects With Intercom, Access Control and Cameras
Intercom
The apartment release button or entry panel can command the same relay/strike path.
Access Control
Readers, keypads and controllers can operate the controlled opening and share lock power or relays.
Security Cameras
Entrance cameras document access events but do not themselves prove the lock or release circuit is healthy.
Common Questions
Electric Strike and Door-Release Questions
Door-release repair service calls start at $150. Localized faults such as a relay, power supply or wiring connection often qualify for the $150–$250 flat rate with a 30-day repair warranty; electric strike or magnetic lock replacement is quoted separately after testing.
Why does my electric strike buzz but not unlock?
A strike can receive power or make a sound and still fail to release because of incorrect voltage, worn strike components, latch pressure, door sag, frame movement or misalignment. Electrical activation does not prove that the latch can move freely, so both the circuit and the physical door should be checked.
Why can I hear the visitor but the door will not unlock?
The communication path and the door-release path are separate. If calling and audio work, troubleshoot the release button, relay, power supply, low-voltage wiring, electric strike or magnetic lock, access-control interface and door alignment before replacing the intercom.
Who repairs electric door strikes in New York City?
Unlimited Applications Security Company troubleshoots electric strikes, magnetic locks, relays, power supplies, intercom-connected releases and access-control door-release circuits across New York City. Serviceability depends on the installed hardware, voltage, door preparation, condition and parts availability. Call (347) 433-6873.
Should I replace the intercom if the door will not open?
Not automatically. If visitor calling and audio still work, the failed component may be the relay, power supply, wiring, electric strike, magnetic lock or the physical door rather than the communication equipment. Test the release path before replacing an otherwise functional intercom.

Door-Release Lead Checklist
What to Tell Us When the Intercom or Reader Works but the Door Will Not Open
What activates the release?
Apartment button, desk button, key fob/card, keypad, telephone entry or another controller.
What does the lock do?
No sound, buzzes but stays locked, releases intermittently, or releases only when pressure is removed from the door.
What changed recently?
Door/closer work, frame adjustment, electrical work, access-control work, power outage or recurring alignment problems.
Why this improves the repair: the same “door will not unlock” complaint can be caused by the release command, relay, power, wiring, electric strike/maglock or the physical relationship between the latch and strike. The intercom should not be replaced until that path is tested.
Need Door-Release Troubleshooting in NYC?
Call with the borough, property type, intercom/access-control brand if known, and exactly what happens when the release command is used.
