Step 1: Remove the Internal Key

The first step is to remove the internal key from the key fob. Turn the key fob over to its back and locate the lever. Push and hold the lever while pulling out the internal key.

Step 2: Open the Key Fob

Next, we need to open the key fob. Use the metal key ring to help pull off the back part of the key fob. Insert the flathead screwdriver between the metal piece and the lip on the edge of the back.

Insert the screwdriver until it feels secure. Firmly but gently twist the screwdriver to create a small separation. Stop and move to the side of the fob, repeating the process to gradually open it without causing damage.

Step 3: Remove the Old Battery

Once the key fob is open, you’ll see the old CR2032 battery. Use the flathead screwdriver to gently get under the battery and wiggle it out. Be careful not to damage any components.

Step 4: Insert the New Battery

Take your new CR2032 battery and ensure the positive side (the side with the battery information) is facing up. Push the battery into place and click it in securely with your thumb.

Step 5: Reassemble the Key Fob

With the new battery in place, it’s time to reassemble the key fob. Click the two plastic pieces back together and insert the internal key. Make sure everything is aligned properly.

Step 6: Test the Key Fob

After reassembling, check if the light on the key fob turns on. If it does, you have successfully replaced the battery. If not, recheck the battery placement and make sure it is secure.
