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