In this guide, I’ll walk you through the steps to change the battery for models from 2012 to 2019. This simple task requires minimal tools and can be completed in just a few minutes.

Tools You Will Need

Before we start, gather the necessary tools. You won’t need much, but having the right tools will make the process easier.

• CR2032 coin battery
• Small flat-head screwdriver
• Paper clip (optional)

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.

Common Issues and Troubleshooting

While replacing the battery is generally straightforward, you might encounter a few issues. Here are some common problems and their solutions:

• Key fob won’t open: Ensure you’re applying enough leverage with the valet key or screwdriver.
• Battery doesn’t fit: Double-check that you have a CR2032 battery.
• Key fob doesn’t work after replacement: Make sure the battery is inserted correctly, with the positive side facing down.
