How It Works
The unit contains a small electric actuator and mechanical latch which receive an electrical signal from the central locking module or the door switch. When activated, the actuator moves the internal mechanism to lock or unlock the door and engages the latch to secure the door shut. Proper electrical connection and mechanical alignment are required for smooth operation.
