<\/figure>\n<\/div>\n\n\nHow Electric Door Release Systems Work<\/h2>\n\n\n\n
When a tenant presses the door release button on their intercom station, a signal is sent to the door entry panel, which then energizes a relay. That relay triggers an electric strike or magnetic lock \u2014 mechanically releasing the door latch and allowing the visitor to enter.<\/p>\n\n\n\n
Any failure in this chain \u2014 from the intercom station signal to the wiring to the relay to the strike \u2014 will result in a door that doesn’t open, even when the intercom itself appears to be working.<\/p>\n\n\n

<\/figure>\n<\/div>\n\n\nCommon Door Release Failures in NYC Apartment Buildings<\/h2>\n\n\n\n\n- Burned-out electric strike \u2014 the most common failure; the strike solenoid burns out from repeated use<\/li>\n\n\n\n
- Failed relay board in the main intercom panel \u2014 the relay that triggers the strike stops responding<\/li>\n\n\n\n
- Broken wiring between the panel and the strike \u2014 especially in older buildings<\/li>\n\n\n\n
- Incorrect voltage to the strike \u2014 the wrong voltage causes the strike to work intermittently or not at all<\/li>\n\n\n\n
- Mechanical door alignment issues \u2014 the door frame shifts and the strike can’t release the latch<\/li>\n\n\n\n
- Magnetic lock power supply failures \u2014 MLK-style mag locks lose holding force when the power supply fails<\/li>\n<\/ul>\n\n\n\n
Frequently Asked Questions: Door Release Repair<\/h2>\n\n\n\n
Why does my apartment building door buzzer work but the door won’t open?<\/strong><\/p>\n\n\n\nIf tenants can hear visitors through the intercom but the door doesn’t release, the problem is almost certainly in the door release hardware \u2014 not the intercom itself. The most common causes are a burned-out electric strike, a failed relay in the main panel, or broken wiring between the panel and the strike.<\/p>\n\n\n\n
How long does door release repair take?<\/strong><\/p>\n\n\n\nMost door release repairs are completed within 1\u20133 hours. If the electric strike needs to be replaced, our technicians carry common replacement strikes for standard door preparations. If a custom-fit strike is needed, it may require a return visit.<\/p>\n\n\n\n
Is door release repair covered by a warranty?<\/strong><\/p>\n\n\n\nYes. All labor performed by our technicians carries a 90-day warranty. Hardware and parts carry the manufacturer’s warranty, which typically ranges from 1\u20133 years.<\/p>\n\n\n\n
Can you repair both magnetic locks and electric strikes?<\/strong><\/p>\n\n\n\nYes. We service all types of door release hardware including electric strikes (fail-secure and fail-safe), electromagnetic locks (maglocks), electric deadbolts, and electric latch retraction devices.<\/p>\n\n\n\n
