Step-by-Step Battery Replacement
Locate the Indentation
First, examine your key fob. On either side, you’ll notice a small indentation in the plastic. This is where you’ll insert your flathead screwdriver.
Insert and Twist
Using your small flathead screwdriver, gently insert it into the indentation. Twist the screwdriver to start opening the device. Be careful to avoid damaging the plastic. If you don’t have a small flathead screwdriver, a regular one will work, but use the corner of the blade to wiggle it in.
Remove the Old Batteries
Once the key fob is open, you’ll see two batteries stacked on top of each other. Carefully remove these batteries. You can use your fingers or the screwdriver to pry them out.
Insert the New Batteries
Take your new CR2025 batteries and ensure the positive side is facing down. Place them one on top of the other in the compartment. Make sure they click into place securely.
Reassemble the Key Fob
Now that the new batteries are in place, all that’s left is to click the key fob back together. Ensure it snaps shut completely to avoid any issues.
Testing Your Key Fob
After reassembling your key fob, it’s crucial to test it to ensure everything is working correctly. Stand near your Audi A8 and press any button on the key fob. If the car responds, your battery replacement was successful.
Common Issues and Troubleshooting
Occasionally, you might encounter some issues even after replacing the battery. Here are some common problems and their solutions:
- Key fob not responding: Double-check the battery orientation.
- Buttons not working: Ensure the key fob is snapped shut properly.
- Intermittent function: Clean battery contacts.
