I have a1999chevy Tahoe and just changed the lock cylinder and now it want start. I was told it needed to have the passlock module releared procedure. I need to know how to do it that. I am disabled and don't have the money to pay a shop.
First try to start the car. If it turns over leave the key in the run position for 10 min. the light may stay on or go off. Turn it off for 10 sec, "must be 10 sec". then try to start may have to repeat two or three times. If that dose not work it could be the BCM body control module. If that dose not work you will need to buy a bypass module. This will disable the passlock system all together.
You are out of luck. If you are not a licensed locksmith or automechanic, you cannot get that information.

never heard of this happening before ,sounds more like the code reader behind the steering lock is playing up.If it is then its dealer only,have a funny feeling this could be an expensive repair.Sorry i couldnt be much more help but this fancy electronic stuff is designed to stop general mechanics like myself from doing repairs.

Wiring diagrams can be found online, however i believe you can re-learn the key by leaving it inside the ignition tumblen and switch it to accesory. Then disconnect the b attery for about ten minutes and then try starting the car without taking the key out.
