When you lock the car, some of its functions and systems are either shut down or activated to help protect the car from theft. For example, the alarm is automatically armed.
Warning
Alarm
The alarm is automatically armed when you lock the car and disarmed when you unlock it.
Gear shift lock
When the car is locked, the gear shift is locked.
Immobiliser
The immobiliser is an anti-theft system that prevents your car from being driven until it's started using a valid key. If your car can't find the key or fails to authenticate it, your car will remain immobilised. If the key can't be found or has a low battery, a notification appears in the centre display. If your car is unresponsive to a battery-powered key, try using a key card. If the car appears to have no power, the cause could be flat batteries or something affecting its electrical systems.
