Step-by-Step Guide

Step 1: Remove the Internal Key

The first step is to flip the key fob over. Locate the lever on the back and push it while holding it down. Pull out the internal key from the key fob.

Step 2: Create a Separation

Now, stay on the back of the key fob and look for a small space between the metal keyring holder and the lip of the key fob. Insert your flathead screwdriver into this space. Wiggle the tool until it feels secure.

Step 3: Twist to Separate

Once the tool is secure, twist it gently but firmly until you feel a small pop. This indicates that a separation has been created on the side of the key fob.

Step 4: Open the Key Fob

Now, insert your tool into the side of the key fob where the separation was created. Twist the tool gently and move it down a little bit, twisting again. The key fob will come apart, revealing the internal battery compartment.

Step 5: Remove the Old Battery

Carefully insert the flathead screwdriver under the battery from the side. Be slow and gentle to avoid damaging the key fob. With a slight twist, the old battery will pop out.

Step 6: Insert the New Battery

Take the new CR2032 battery and ensure the positive side is facing up. Begin by sliding one side of the battery into the compartment, then click the other side down. The battery should sit flush and secure.

Step 7: Reassemble the Key Fob

Click the two halves of the key fob back together. Ensure that the light comes on to confirm that the battery is properly installed. Reinsert the internal key, and you’re good to go!
