Steps to Change Your 2005 Volkswagen Key Fob Battery

Locate the Key Slot: On the side of your VW key fob, you’ll find a small, rectangular slot. This slot is designed to help you separate the key fob’s two halves.
Insert and Twist the Screwdriver: Gently insert the flat-head screwdriver into the key slot. Apply slight pressure and twist the screwdriver to release the catch holding the two halves together.
Separate the Key Fob Halves: Carefully pry open the key fob, revealing the battery compartment. Be cautious not to touch any internal components other than the battery.
Remove and Replace the Battery: The old battery will be visible. Using your fingernail or the edge of the screwdriver, carefully lift it out. Avoid touching the battery terminals. Now, place the new CR2032 battery into the compartment, ensuring the positive (+) side faces up, just like the old battery.
Reassemble the Key Fob: Align the two halves of the key fob, making sure they fit snugly together. Press the halves together until you hear a click, indicating the catch has engaged.
Test Your Key Fob: Try unlocking and locking your car doors using the key fob buttons. If the buttons respond, congratulations! You’ve successfully changed your key fob battery. If not, double-check that the battery is properly installed and try again.

Troubleshooting
