I recently had to get a new Key Fob for my Grand Cherokee. I took it down and they programmed it, it showed programming was complete. However, when you push lock , unlock or panic it does not work. We tried 3 different key fobs and still no response. Any idea what the issue may be. Batteries in the Key Fobs were all good. I just really hate to have to leave the Jeep there and pay for them to try and locate the issue.
