- Open the Key Fob: Use a small flathead screwdriver or your fingernail to carefully pry open the key fob at the designated slot.
- Remove the Old Battery: Gently pry out the old battery. Note the orientation of the positive (+) and negative (-) sides of the battery.

What if My Jeep Key Fob Still Doesn’t Work?
If you’ve replaced the battery and your Jeep key fob still isn’t working, there are a few other potential culprits:
