Do these cars use a separate key for the door lock or is it the ignition key?
Have a 99 GTP and the key will not work in the door. Before this I had an 04 Regal GS and had the same problem. Both were purchased used and both only had ignition keys. Not sure if I have to spray down the door lock or if I'm just using the wrong key. I know in the early 90's and before they used seperate keys, not sure when it changed over. My 96 Saturn had a single key.
Sorry I know its a stupid question.
