Buick Repair Questions? Ask a Mechanic for Answers ASAP
Hi, I'm Ron and I will be helping you today.Stand by for a moment while I prepare your answer.
I attached 2 docs for you do read and perform.
Do the re-learn first, and if that does not work, then try the security reset.
If that doesn't work, then you need to have the computer system scanned for error codes and data.
I will opt out so you can get another expert.
