How to Replace the Remote Battery on the Volkswagen Passat?

Model: Volkswagen Passat B8, 3G, MK 8 - Years 2014-2023
Part: Key

To replace the battery in the remote for the Volkswagen Passat, leverage an object in the side groove of the device: this will allow you to open the remote by separating the top part of the casing from the bottom. The internal battery will then be accessible, and you can remove it from its housing to replace it with a new one. Once the replacement is complete, close the remote again by repositioning the top half onto the bottom; at this point, check that the device functions correctly.
