Just recently, my remote entry quit working. I tested the batteries in the remote. They were good. I still replaced them and nothing. This is what does work. Inserting the key in the door lock, the key does lock and unlock the car including the trunk. Is there any checks I can do to verify what is broken? I don't want to yank the SKREEM yet until I have a better idea of the issue. I would rather just send a key to get it duplicated.
