Step-by-Step Guide

Step 1: Remove the Internal Key

Look at the side of the key fob. You will see a button labeled “push.” Hold down this button and pull out the internal key. This will reveal the keyhole and a horizontal line perpendicular to it.

Step 2: Open the Key Fob

Insert a flathead screwdriver into the horizontal line. Twist the screwdriver gently while holding the device loosely. The key fob will crack open, allowing you to access the internal components.

Step 3: Remove the Circuit Board

Set the back cover aside and carefully remove the small circuit board inside. Be cautious not to touch the circuit board excessively to avoid any damage.

Step 4: Extract the Old Battery

Using the flathead screwdriver, insert it between the battery and the plastic housing. Apply gentle pressure while wiggling the screwdriver to slide it under the battery. The old battery will pop out easily.

Step 5: Insert the New Battery

Take your new CR2032 battery. Ensure the positive side, marked with a plus sign, is facing up. Place the battery into the designated slot, making sure it touches the circular contact point inside the key fob.

Step 6: Reassemble the Key Fob

Put the circuit board back into the key fob housing. Click the back cover onto the device, ensuring it snaps securely. Finally, reinsert the internal key into its slot.

Testing the Key Fob

After reassembling your key fob, test it to ensure it works correctly. Press the buttons to check if the key fob is responsive. If it functions properly, you have successfully replaced the battery.

Additional Tips

• Handle the circuit board with care.
• Avoid touching the battery terminals.
• Dispose of the old battery properly.
