Step-by-Step Guide

Step 1: Remove the Internal Key

First, turn over the key fob and press the small button to release the internal key. This will allow you to access the battery compartment.

Step 2: Locate the Groove

With the internal key removed, look inside the compartment. You will see a groove next to the keyhole where the key was situated. This groove is where you’ll insert your flathead screwdriver.

Step 3: Separate the Key Fob Halves

Insert the flathead screwdriver into the groove and gently twist it. This action will start to separate the two halves of the key fob. Continue to twist until the entire key fob comes apart. Be careful to keep the circuit board in place and set it aside safely.

Step 4: Remove the Old Battery

Now that the key fob is open, locate the battery compartment. Use your flathead screwdriver to gently pry and rock the old CR2032 battery out of its position. Take care not to damage any components during this process.

Step 5: Insert the New Battery

Take a brand new CR2032 battery and ensure the positive side, marked with text and information, is facing down. Slide the battery into the bottom part of the metal component first, then click the top into place.

Step 6: Reassemble the Key Fob

With the new battery in place, it’s time to reassemble the key fob. Align the two halves and press them together until they click securely. Finally, reinsert the internal key.

Testing the Key Fob

To ensure everything is working correctly, test the key fob by pressing a button. If the light comes on, your new battery is functioning, and the key fob is ready to use. If you’re reusing an old battery, the light may not come on, indicating the battery may need to be replaced.
