Changing Your Mercedes-Benz Key Fob Battery Step by Step

Mercedes-Benz key battery replacements are pretty simple to perform and only take a few minutes. However, the process can vary depending on what kind of Mercedes-Benz you drive around Pahrump. Older Mercedes-Benz vehicles usually have the Mercedes-Benz SmartKey®, while newer models tend to have the Mercedes-Benz Chrome Key.

After you determine the key type for your Mercedes-Benz, the rest is a piece of cake. Here’s how to change your Mercedes-Benz key fob battery:

Mercedes-Benz Key Battery for a SmartKey®

Hold the key in your hand by the keychain.

Pull the sliding tab, and pull out the valet key.

Move the valet key to the opposite side of where it can be fully inserted, then push down.

Remove the key backing, and replace the battery.

Reassemble the SmartKey®, then test for proper functionality.

How to Replace a Mercedes-Benz Key Battery for a Mercedes-Benz Chrome Key

If you own a newer Mercedes-Benz model, chances are you might actually have a Chrome Key. Opening your Mercedes-Benz key and changing the battery differs slightly with the Chrome key.

Pull on the bottom tab of the key, away from the rest of the fob. Pull until the key releases.
Then, you should see a small gap in the fob where the key was. Press the key into the flat end of the fob to open the Chrome Key’s cover.
Once you remove the key cover, you’ll be able to see the battery. Remove the battery, and replace it with the new one while making sure the correct side is facing up.
