The Volvo Door lock is a mechanical device paired with an electric actuator that is used for locking and unlocking your front door, rear door, trunk lid, hatch, hood or tailgate. The mechanical side usually involves a mechanism that moves when the electronic actuator pushes or pulls it which in turn locks or unlocks the door latch.
Why do Volvo locks break? The most common causes of a lock failure are; a metal rod gets bent, a plastic clip cracks or the electrical actuator burns up.
