whats the usual immobiliser sequence
 

as in when you approach the car is the red led on behind the steering wheel and does it go off when you open the car with the fob or does it go off when you turn ignition off,i have no manual and haven't had car long enough to notice.ref my non starter post the last time I had batt connected the light was on constant no matter what so when the frost clears a bit im gonna go reconnect batt and see what happens
cheers daz

locking and unlocking and alarm has nothing to do with the immobiliser function.

The immobiliser is purely the transponder chip in the key. The light should go out about 3-4 seconds after you turn the ignition on. If it flashes or stays on then it's either a fault or an unrecognised key

Immobiliser

- prevents unauthorized operation of the vehicle by disabling the engine
- engine will shut off after 2 seconds of running if an invalid key is used to start the vehicle
- chip [transponder], as Richard says is embedded into the grey keys which are programmed to your vehicle
- so your [SKIS] sentry key immobilizer system does not need to be armed or activated
- the operation of the system is automatic regardless of whether or not the vehicle is locked or unlocked

Handbook

During normal operation, the Theft Alarm / Immobilizer Light will come on for three (3) seconds immediately after the ignition switch is turned on for a bulb check. Afterwards, if the bulb remains on, this indicates a problem with the electronics. If the bulb begins to flash after the bulb check, this indicates that an invalid key has been used to start the vehicle. Both of these conditions will result in the engine being shut off after two (2) seconds of running. Keep in mind that a key which has not been programmed is also considered an invalid key even if it is cut to fit the ignition lock cylinder for that vehicle. If the Theft Alarm/Immobilizer Light comes on during normal vehicle operation (vehicle has been running for longer than 10 seconds), a fault has been detected in the electronics and the vehicle should be serviced as soon as possible.

This system monitors the vehicle doors and ignition switch for unauthorized entry or operation. When the alarm is activated, the system provides both audible and visual signals. The horn will pulse, headlights/park lights will flash, the Vehicle Theft Alarm/Immobilizer light, located in the instrument cluster, will flash, and the vehicle will not start. If the alarm is triggered and no action is taken to disarm it, the system will turn off the horn after three minutes and after 15 minutes of light only operation the system will then rearm itself. Once the alarm is set, and the liftgate button on the keyless entry transmitter is pressed, on a non-power liftgate vehicle, you have a 30 second one time access into the liftgate area. If the liftgate is not opened within 30 seconds the liftgate will remain locked.

thanks for that

- regardless of the FOB / doors, is the the grey IGN key you were / are are using programmed to your vehicle ?
