- New batteries
- Fuse puller
Step 1 – Check functionality of keyless remote
Before programming an existing keyless remote that no longer appears to be functioning properly, make sure the batteries are in good working order. As well, it’s recommended that you open your keyless remote and check the connectors inside for good, clean contact points. The retaining clip must also be in good shape, or your keyless remote might not work properly.

Step 2 – Troubleshoot Wireless Control Module (WCM)
It could be affecting the usefulness of your keyless remote.
- Turn off your vehicle if it’s not already.
- Remove the negative (black) connector on your car battery for up to four hours.
- Alternatively, open your fuse box and pull out the Ignition Off Draw (IOD) fuse using a pair of fuse pullers or tweezers.
- Wait 30 seconds and reinstall the IOD fuse, checking that it’s properly seated inside the fuse box.
- This will reset the WCM and restore your Remote Key Entry (RKE), ignition key programming and remote start.
- If the entire module needs to be replaced, you will need to visit a local Jeep dealership.

It’s not necessary to remove your car battery and remove the IOD fuse. Doing one DIY solution will suffice.
Step 3 – Visit local Jeep dealership
Visit a local Jeep dealership to have one or more of your keyless remotes reprogrammed. The dealer can also troubleshoot your key fob and WCM for additional problems or failings. Expect to pay around $50 per keyless remote.
