If you're having trouble with your existing key fob, the issue is likely:
* Battery: Replace the battery in your key fob. This is the most common problem.
* Key Fob Malfunction: The internal electronics of the key fob might be failing. You'll need a replacement key fob and likely to have it programmed by a dealership or locksmith. Programming usually involves plugging a diagnostic tool into the car's OBD-II port.
* Receiver Issues: Less common, but the receiver in your Jeep could be faulty. This would require professional diagnosis.
In summary: There's no "configuration" involved in the sense of programming additional features. Troubleshooting focuses on replacing the key fob battery or obtaining a new, programmed key fob.
