Removing the Valet Key
First, flip over the key fob and locate the small lever. This lever is essential for releasing the valet key.

- Locate the small lever
- Push the lever down
- Release the valet key
With the valet key removed, you can proceed to the next step.

Using a Flat-Head Screwdriver
If you have a flat-head screwdriver on hand, follow these steps:
- Insert the screwdriver into the indentation
- Give it a slight twist
- Repeat on the other side
- Twist to loosen the key fob halves
This should create an opening, allowing you to access the battery compartment.
Using Your Fingers
If you don’t have a screwdriver, you can still open the key fob using your fingers:
- Find the small groove
- Use your fingers to pry open the groove
- Repeat on the other side
- Use the valet key as a tool if needed
Once the key fob is open, you can proceed to replace the battery.

With the key fob open, you will see a small piece of plastic covering the battery. Follow these steps to replace the battery:
- Remove the plastic cover
- Slide out the old CR2025 battery
- Insert the new CR2025 battery

Ensure the new battery is securely in place before closing the key fob.
