There are 2 types of security systems on that car.
1) is the ATA alarm system & tries to protect the car from being stolen. NOISE & Lights.

2) is the key recognition system (DAS) that requires having the correct key in the ignition.
It will keep the engine from starting by shutting off the injection.

ATA is controlled by the central locking.
DAS is a separate computer that is MARRIED to the fuel system computer & can not be disconnected!
