The range for locking and unlocking the truck with the factory remote just changed from about 20-30 feet to about 3 feet. I tried a new battery in the remote but no luck. I even tried the second remote which hasn't been out of the desk since I brought the truck home for the first time and it only works from about 3 feet as well. I'm thinking the reciever in the truck has a problem. Any suggestions?
