Locate The Key Release
Locating the key release on your Volkswagen key is the first step to change the battery. This small part lets you remove the key blade easily. It allows access to the battery compartment inside the key fob.

Buy From A Trusted Source
Choose a battery from a reliable store or brand. Low-quality batteries may not last long or fit properly. Genuine or high-quality batteries ensure your key works without issues for a long time.
Consider Battery Life And Power
