How to Replace the Battery in a Jeep Key Fob?
2 Answers
Purchase the original battery, which is a small battery, ensuring the voltage and model number are the same. After removing the key fob, take out the mechanical key. The mechanical key can be pulled out by pressing a small button. Use a small flat-head screwdriver to pry open the key fob. There is a small gap in the middle of the key fob, and it can be gently pried open by twisting. Use a small flat-head screwdriver to remove the old battery and install the new one. Pay attention to the orientation of the battery, ensuring it is installed correctly in the right position.
I remember when I first got my Jeep, I changed the key fob battery myself—it was pretty straightforward. Usually, there's a small gap on the back cover of the key fob, and you can gently pry it open with a small screwdriver from home to reveal the battery. The battery model is mostly CR2032, which you can easily find at any supermarket. After opening the cover, carefully remove the old battery, making sure not to damage any small internal components. When inserting the new battery, pay attention to the correct orientation—the side with the plus sign should face upward. After reassembling, press the key buttons a few times to test the light or remote functions to confirm everything works. Don’t forget that some older Jeep key fobs may have a mechanical key part, so be careful not to lose it during the battery replacement. Reducing frequent button presses in daily use can help extend the battery life. If the key fob still doesn’t light up after DIY, the battery might be inserted backward or not making proper contact—just double-check it.
