Step-by-Step Battery Replacement
Step 1: Release the Internal Key
Start by pressing the button on the key fob to release the internal key. Set the key aside for now.
Step 2: Open the Key Fob
Look at the hole where the key was inserted. Above this hole, you will see a small slot designed for opening the battery compartment. Insert a flathead screwdriver into this slot and gently twist it. The key fob will start to come apart, and you can then finish opening it with your fingers.
Step 3: Remove the Old Battery
Once the key fob is open, locate the battery, which is housed in a small plastic compartment. Use a precision screwdriver to carefully remove the battery. Insert the screwdriver on the side of the battery, push down to the bottom, and pry it out. If you don’t have a precision screwdriver, a toothpick can also work.
Step 4: Insert the New Battery
Take a new CR2032 battery and ensure that the positive side (the side with the battery information) is facing down. Place the battery into the compartment and push it down into the metal component before clicking it into place.
Step 5: Reassemble the Key Fob
Before closing the key fob, ensure that the circuit board and rubber components are correctly positioned. The buttons on the rubber component should align with the buttons on the circuit board. Once everything is in place, click the two halves of the key fob back together.
Step 6: Reinsert the Internal Key
Finally, reinsert the internal key into the key fob. Your key fob battery replacement is now complete.
