DURING RELEARN PROCESS DOES ANTI THEFT LIGHT HAVE TO BLINK?

ignition lock cylinder

The key cylinder itself does not require programming of any kind. If you are programming keys, you'll need the proper diagnostic tool to follow programming procedures for the related immobilizer system.

when replacing lock cylinder doesn't computer have to relearn new cylinder

The cylinder does not get programmed. The key is programmed to the vehicle. If you haven't changed the key, then nothing needs programmed. If you have changed the key, the vehicle needs to learn the key, using a suitable diagnostic tool that usually a dealership or locksmith will have.

The ignition *KEY* is the key here. Lock cylinder itself doesn’t have to be programmed. Probably need to contact locksmith. Good luck!

kinda confused here my 96 grand am does not have chip in key so ive been told to replace ignition lock assembly and perform a relearn process. after replacing lock assembly turn ignition to start then wait ten minutes until anti theft light quits blinking turn to off position wait 5 seconds and car should start but my anti theft light does not blink stays solid?

I’m sorry that you were misinformed about the ‘correct’ procedure. Good luck with it!

As Pushrod said -- you were totally misinformed. This vehicle does require a chip key. No idea where the advice you were given came from.

thanks guys maybe i'll take that 250.00 miss information back to the parts store and contact dealer with vin# for key thanks again
