Buick Repair Questions? Ask a Mechanic for Answers ASAP
Hello, my name is Bobby. Thank you for the question. Typically this occurs when the contacts in the remote itself are shorting or dirty. I would either try a spare remote if you have one or take yours apart and clean it out with contact cleaner. If the problem is not the remote then the failure is more than likely in the body control module. Please let me know if you need more help.
If it is still in the same remote then the issue is more than likely the remote itself. The circuit board may have a short. The only way to verify it is with another remote that is known to be good. Do you have a spare remote?
