Step-by-Step Guide
1. Remove the Valet Key
The first step is to remove the valet key from the key fob. Flip the fob over and locate the small latch. Pull this latch towards you to release the valet key. Once the key is out, set it aside.
2. Separate the Key Fob
Next, you need to separate the backing of the key fob from the main part. This can be a bit tricky, but using the valet key, you can gain some leverage. Insert the key into the small gaps at the top and twist gently to create a separation. If you’re having trouble, a small flat-head screwdriver can also be used.
3. Open the Key Fob
Once you have a small gap, use your hands to pull the key fob apart. Hold the base part down and pull the backing away from the main body. Be careful not to force it too hard to avoid damaging any components.
4. Remove the Old Battery
With the key fob open, you can now see the battery. There is a small metal piece that holds the battery in place. Make sure this stays intact. Use a flat-head screwdriver or a paper clip to carefully pop out the old battery.
5. Insert the New Battery
The battery you need is a CR2032 coin battery. When inserting the new battery, ensure the positive side (marked with a + sign) faces down. The negative side should be facing up towards you.
6. Reassemble the Key Fob
After inserting the new battery, line up the backing with the main part of the key fob. Press them together until they snap back into place. Ensure everything is tight and secure.
7. Replace the Valet Key
Finally, slide the valet key back into its slot until it clicks into place. Your key fob is now ready for use with its new battery.
