Power Door Locks Description and Operation
WARNING: This page is about a different car, the 2005 Suzuki Swift +, 2005 Pontiac Wave, and 2005 Chevrolet Aveo. However, it is still accessible from the selected car via links, so may be relevant.
The power door locks use a solenoid that is contained in each door lock assembly. The door locks are activated by the actuator on the inside door handle or by the lock cylinder on the driver's side door only. When the driver's side door is locked or unlocked by the actuator or lock cylinder, all doors are locked or unlocked accordingly.
