DIY Programming Methods for a 2004 Jeep Grand Cherokee Key Fob
For many 2004 Jeep Grand Cherokee models, you can program a new key fob yourself using the following steps:
- Gather your materials: You will need all your existing working key fobs and the new key fob you want to program.
- Enter the programming mode: Insert a working key fob into the ignition and turn it to the “ON” position (do not start the engine). Repeat this process quickly eight times, ending in the “ON” position. The car’s door locks should cycle, indicating you’ve entered programming mode.

- Door locks don’t cycle: Double-check that you are following the steps correctly and using a working key fob. Try repeating the process from the beginning.
