What You’ll Need to Replace the Battery

Replacing your 2020 Jeep Grand Cherokee key fob battery is a straightforward process. Here’s what you need:

  • A new CR2032 battery: You can find these at most convenience stores, auto parts stores, and online retailers.

How to Replace the 2020 Jeep Grand Cherokee Key Fob Battery: A Step-by-Step Guide

Replacing the battery in your 2020 Jeep Grand Cherokee key fob takes just a few minutes. Just follow these simple steps:

  1. Locate the key fob release button: Look for a small button on the back of your key fob. It’s usually located near the key ring.

  2. Release the metal key: Press the release button and gently pull out the metal emergency key from the fob.

  3. Separate the key fob halves: Use a small flathead screwdriver or a plastic pry tool to carefully pry open the key fob casing. Insert the tool into the seam along the edge of the fob and gently apply pressure to separate the two halves.

  4. Remove the old battery: Once the fob is open, you’ll see the CR2032 battery. Carefully remove the old battery by prying it out with your screwdriver or pry tool.

  5. Insert the new battery: Place the new CR2032 battery into the fob, making sure the positive (+) side is facing up.

  6. Reassemble the key fob: Align the two halves of the key fob and press them together firmly until you hear them snap back into place.

  7. Reinsert the metal key: Slide the metal key back into its slot on the fob until it clicks.

  8. Test the key fob: Make sure the buttons are working correctly by locking and unlocking your vehicle.

What if My Key Fob Still Doesn’t Work?

If you’ve replaced the battery and your 2020 Jeep Grand Cherokee key fob is still not working correctly, here are a few things you can try:

  • Check the battery installation: Make sure the new battery is properly seated in the fob and the positive (+) side is facing up.
  • Resynchronize the key fob: Consult your vehicle’s owner’s manual for instructions on how to resynchronize or reprogram your key fob.
  • Check for other issues: There might be a different issue with your key fob, such as a malfunctioning button or a problem with the vehicle’s keyless entry system.

“In some cases, especially if the key fob was dropped or exposed to water, internal components might be damaged, requiring a replacement fob or professional repair,” says John Miller, a certified automotive electrician with over 15 years of experience in automotive diagnostics and repair. “If you suspect a more serious issue, it’s always best to consult with a qualified automotive technician or your dealership.”
