How to replace the battery of a Mercedes key

Model: Mercedes Mercedes Various
Part: Key

To replace the battery of a Mercedes Benz vehicle key, we need to pull the top part of the remote to remove the metal key inside. With the metal key, we open the remote by levering on one of the two sides. We remove and insert the battery and then close the remote. We insert the key inside the remote and finish by testing the key/remote functionality by opening or closing the vehicle from a distance. If the issue with the key function persists, it may be necessary to reprogram the remote.
