Step-by-Step Guide: Changing Your Chrysler Key Fob Battery
How do I change a Chrysler key fob battery? Follow these steps:
-
Gather Your Tools: You’ll need a small flathead screwdriver (or a similar prying tool) and a replacement battery (CR2032 is the most common type). It’s a good idea to have a soft cloth to protect the fob’s surface.
-
Locate the Battery Compartment: The battery compartment location varies slightly depending on the key fob model. Some have a visible seam where you can insert the screwdriver. Others require you to remove a physical key (if present) to reveal the battery compartment access point. Refer to your owner’s manual if unsure.
-
Open the Key Fob: Gently insert the flathead screwdriver into the seam or access point. Twist or pry carefully to separate the two halves of the key fob case. Be gentle to avoid damaging the plastic.
-
Remove the Old Battery: Once the key fob is open, you’ll see the battery. Note the battery’s orientation (+ side up or down). Use the screwdriver or your fingernail to gently pry the old battery out of its holder.
-
Insert the New Battery: Insert the new battery into the holder, ensuring the correct orientation (as noted in step 4). A CR2032 battery is often used.
-
Reassemble the Key Fob: Carefully align the two halves of the key fob case and snap them back together. Ensure they are securely closed.
-
Test the Key Fob: Press the buttons on the key fob to test if it’s working correctly. Verify that the car locks and unlocks, and that the panic button functions.
Common Mistakes to Avoid

- Using the Wrong Battery Type: Double-check that you’re using the correct battery type. A CR2032 is a common battery type. Consult your owner’s manual.
- Damaging the Circuit Board: Be careful not to touch or damage the circuit board when changing the battery.
- Forgetting to Reassemble Properly: Ensure the key fob case is securely closed to protect the internal components.
