Central Locking
Central locking locks and unlocks all doors at once using the key, a remote or a button.
What is Central Locking?
Actuators in each door, tailgate and fuel flap perform the movement. The body control module controls the system. Many cars lock automatically when driving off. Many systems offer selective unlocking, where the first press opens only the driver's door, and a double-locking (deadlock) mode that disables the interior handles.
How it works
The control module powers the actuators in one direction to lock and the other to unlock.
Why it matters for your car
If one door does not respond, its actuator or wiring is usually at fault. Most cars have a mechanical key backup.
