When your vehicle's key fob stops working without warning, the battery is most likely the cause and needs to be replaced. To find the correct battery for your Jeep key fob, use this battery finder by simply entering your year, make, and model. Jeep remotes most commonly use a CR1616, CR2016, CR2450, & CR2032 battery. Most key fob batteries cost less than $6 and are available for purchase online.
To open and replace the battery in your Jeep key fob, follow these instructions:
For newer Jeep models, insert the hidden key into a designated slot to open the case. For older Jeep models, use a thin object (like a flathead screwdriver) to pry open the case at the notch. After opening the case, gently lift the circuit board to access the battery. Before removing the battery, note how it fits in the case. Next, replace the old battery with the new one and close the case. Test your key fob's functionality by pressing buttons to ensure it is working properly. If it doesn't work, adjust the battery by ensuring the connections are clean and in contact with the battery.
To see step-by-step video instructions on replacing your remote's battery, search for your Jeep key fob on our YouTube page. If you cannot find your specific Jeep key fob, you can find a video showing the battery replacement process of a different remote that is the same type as yours.
There are five types of key fobs:
- Standard Remotes
- Exactly as it sounds, just a remote with no other special features
- Flip Keys
- A remote with an attached key that flips out like a switchblade
- Remote Heads
- A remote with a key blade sticking out of it, the key blade does not retract or hide
- Fobik Keys
- A remote with a key hidden inside, the key fob and key blade are not connected
- Smart Keys
- A remote that is often associated with push-to-start
If changing your Jeep key fob's battery does not resolve your issue, you may need to replace your Jeep key fob entirely.
