Power Door Locks Description and Operation

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 side door only. When the driver side door is locked or unlocked by the actuator or the lock cylinder, all doors are locked or unlocked accordingly
