Step-by-Step Guide to Changing Your Jeep Key Fob Battery
The process for a Jeep remote battery change is generally straightforward. It involves carefully opening the fob, removing the old battery, and inserting a new one.
What You’ll Need
- New Battery: Ensure you have the correct Jeep transmitter battery type (usually CR2032).
- Small Flathead Screwdriver or Pry Tool: A credit card or guitar pick can also work as a gentler alternative.
- Clean Cloth: To handle the new battery and keep the fob clean.
How to Open Your Jeep Key Fob
This is often the trickiest part. Different Jeep models have slightly different fob designs, but the general principle remains the same: find a seam and gently pry it open.
For Fobs with a Visible Seam:
- Locate the Seam: Look for a thin line running around the edge of the key fob where the two halves meet.
- Insert the Pry Tool: Carefully insert the tip of your small flathead screwdriver or pry tool into this seam.
- Gently Twist: Apply gentle, steady pressure to twist the tool. This will create a small gap.
- Work Around the Edge: Once a gap is created, slowly work your tool around the seam, prying gently as you go. The fob should pop open into two halves. Be patient and avoid forcing it, as you could damage the plastic.
For Fobs with a Notch or Release Button:
Some Jeep key fobs, particularly newer ones for models like the Jeep Wrangler key fob battery or Jeep Grand Cherokee key fob battery, might have a small notch or a release button.
- Locate the Notch/Button: Examine your fob closely for a tiny slot or a small button.
- Insert Tool: If there’s a notch, insert your flathead screwdriver or pry tool into it. If there’s a button, press it with a pointed object.
- Pry or Slide: In some cases, pressing the button might allow one part of the fob to slide off, or it might reveal a place to insert a tool to pry the halves apart.
Pro Tip: If you’re unsure how to open Jeep key fob, it’s a good idea to search for a specific video tutorial for your Jeep model. Seeing it done can make a big difference.
Replacing the Old Battery
Once the fob is open, you’ll see the battery.
- Identify the Battery: The round, coin-like battery will be visible.
- Note the Orientation: Pay attention to which side of the battery is facing up. Usually, the positive (+) side is facing up.
- Remove the Old Battery: Use your fingernail or the tip of your pry tool to gently lift the old battery out of its holder. Don’t use excessive force.
- Insert the New Battery: Place the new battery into the compartment with the correct orientation (positive side up). Ensure it sits snugly.
Reassembling the Key Fob
- Align the Halves: Carefully align the two halves of the key fob.
- Snap Them Together: Press the halves together firmly until they snap back into place. You should hear a click as they secure.
- Test the Fob: Press the buttons to ensure your Jeep key fob replacement worked and your remote is functioning correctly.
Specific Model Considerations
While the general process is similar, there can be minor differences depending on your Jeep model.
Jeep Cherokee Key Fob Battery Replacement
For most Jeep Cherokee models, the key fob design is fairly standard. You’ll typically find a seam around the perimeter that you can gently pry open with a small flathead screwdriver. The CR2032 battery is the usual suspect.
Jeep Wrangler Key Fob Battery Change
Modern Jeep Wrangler key fobs, especially for the JL generation, often feature a sleeker design. Some may have a small notch on the side or back where you can insert a tool to separate the casing. Again, the CR2032 is the common battery.
Jeep Grand Cherokee Key Fob Battery Dying

Troubleshooting Common Key Fob Issues After Battery Change
Sometimes, even after a Jeep key fob battery replacement, you might encounter problems.
Jeep Key Fob Not Working After Battery Change
- Incorrect Battery Orientation: Ensure the positive (+) side of the new battery is facing the correct way.
- Dead New Battery: Though rare, a new battery can sometimes be faulty. Try a different brand-new battery.
- Dirt or Debris: Check the battery contacts and the inside of the fob for any dirt or debris that might be preventing a good connection. You can gently clean these with a pencil eraser or a cotton swab lightly dampened with isopropyl alcohol (ensure it dries completely).
- Damaged Fob: If the fob was dropped or mishandled during the battery change, internal components might be damaged.
- Key Fob Programming: In very rare cases, especially with older models or if the battery was out for an extended period, the key fob might need to be reprogrammed to your Jeep. This usually requires a visit to the dealership or a qualified automotive locksmith.
Other Key Fob Problems
- Buttons Sticking: If buttons feel sticky, a tiny amount of compressed air might help dislodge any debris. Avoid using liquids inside the fob.
- Fob Fell Apart: If the fob didn’t snap back together securely, check for any obstructions or broken clips.

- Keep it Dry: Moisture can damage the internal electronics.

- Consider a Fob Cover: A protective silicone cover can offer some defense against drops and scratches.
