I bypassed the ignition key resistor in our 93 Pontiac Bonneville with the closest resistor I could find. Put it all back together and things worked fine.
Daughter lost key so I had a standard GM key blank, B-48 , copied. The key goes in but the lock does not turn. To my eye the copied key looks perfect.
Question, does the resistor contacts in the proper ignition key also have something to do with allowing the ignition lock to turn or did the spare key I have made look good but was not close enough.
Thank you for any help with this problem, I don't want to spent the 40 or more dollars for the proper spare key if I don't have to.
