Opel Corsa: Vehicle security / Anti-theft alarm system

The anti-theft alarm system is combined with the anti-theft locking system.

It monitors:

  • doors, tailgate, bonnet
  • passenger compartment including adjoining load compartment
  • ignition


All doors, the load compartment and the engine compartment must be closed and the electronic key must not remain in the vehicle.

The system is self-activated 45 seconds after locking the vehicle.

If a door, the tailgate or the bonnet is not properly closed, the vehicle is not locked. However, the anti-theft alarm is self-activated after 45 seconds.


Changes to the vehicle interior such as the use of seat covers and open windows, could impair the function of passenger compartment monitoring.
