if the vehicle has a factory immobilizer the original key has a transducer in the base of it that activates & deactivates the immobilizer when it is put in or pulled out of the ignition switch, if the key that you are trying to use has a transender in it you may have to takef it to a buick dealer to get it coded,if it has,'t got a transducer it will never start the vehicle.....hope this helps....cheers
When you turn the key in the ignition, the ECU will ask the immobilizer if it can start thecar. If the signal is not sending then immobilizer error will show.There is a way to deactivate the immobilizer. The procedure is as follows:--
To deactivate the immobiliser just turn the ignition 3 times on and off and the immobiliser will deactivate .But if still the same problem then this could be the immobiliser read coil around the ignition switch or its a flat battery problem.Thanks. you can rate this solution and show your appreciation.
possibly faulty dashboard or key...immobiliser is combined with the dash display and may have become faulty after battery went flat.....try to get the key coded or try a spare key if you have one
BMW E36 immobilizer Hope the following will help. Had similar problems. The transmitter buttons on keys is for central locking and alarm. Inside the key at the front there is a small electronic/magnetic chip that looks like a block. About 8mm long, 2mm deep and 4mm wide, not connected to any pc board. This is the immobilizer. It must match the receiver that is located behind the ignition switch. If it is loose and too far away from the receiver it won?t deactivate it. If you made a spare key it will switch on electrics but won?t start the car. If you don?t have an immobilizer chip any alarm shop will be able to program a new chip or install a new pair for your keys. There is a way to disable the immobilizer but rather have it fix and protect your car. I read an article somewhere (perhaps bmw e36 blog) of people removing this immobilizer. Good luck
most likely cause is the gauge cluster, this will have to be tested and service by your local dealership because the dash cluster and keys have to be coded. I have seen the immobilizer loose it's coding for apearantly no reason. therefore have them recode cluster and see if problem goes away, if it doesn't the gauge cluster will have to be replaced.
