A buzzer or intercom entry system lets someone inside release a door for a visitor. When it fails, the problem is usually the electric strike, the door alignment, or the power supply, rather than the intercom itself. We diagnose and repair the door-release side and coordinate with the intercom provider when the fault is in their equipment.
When to call us
- Pressing the buzzer does nothing at the door.
- The strike hums but the door does not open.
- The door releases only if someone pushes it.
- The door no longer latches after being released.
How the job works
- We ask what happens when the buzzer is pressed.
- The door, latch and strike are checked mechanically.
- Power and wiring at the strike are tested.
- Faulty strikes or power supplies are repaired or replaced.
- The system is tested from each suite or handset.
Where buzzer faults usually are
When someone presses the release button and nothing happens at the door, there are three places to look: the button or intercom, the wiring and power supply, and the strike and door. In practice, the strike and door are the most common culprits, because the strike has worn after thousands of cycles, or the door has shifted so the latch presses on the strike and it cannot release under load.
A simple test is whether the door releases when someone gently pulls it closed as the button is pressed. If it does, the door needs adjustment. If not, the strike or power needs testing.
What affects the price
The dispatcher explains the service call before anyone is sent, and the technician confirms the total with you before starting any work that adds cost. The main price drivers are:
- Mechanical adjustment versus new strike.
- Power supply or wiring faults.
- Door type and frame.
- Coordination with the intercom provider.
