Hello, my truck is a 97 C1500. It had some custom work done on it after it left the factory and before my grandfather purchased it from the dealer. The custom shop (Pulliam-Watkins Enterprises Country Coaches) is long out of business, so I am unable to get in touch with them. I have not been able to use my remote start/locks for a while now. I noticed yesterday that the LED no longer lit up on the remote, so I thought a dead battery was the culprit. Today, I got a new battery and the LED lights up just fine but it still does not work. Does anybody have an idea for how to reprogram the remote with the truck or where I could find more guidance on that? I did some work a while back and had the battery disconnected for several days, so I wonder if it could have become unprogrammed during that time. Also, where is the receiver on the truck for the remote in case that’s the issue? As I said, the truck had custom work done, so this may all be invalid, but I want to check off all the boxes before assuming that. I’ve attached a picture of the remote since it isn’t stock either.
