How to Change the Battery on a Mercedes-Benz Key Fob

Here’s what you need to know about how to replace a Mercedes-Benz key fob battery:

• What Type of Key Fob Do You Have?: There are two types of key fobs your vehicle may utilize: the newer Chrome SmartKey® or the older SmartKey®. The type of key you have dictates the Mercedes-Benz key fob battery change process.
• Choose the Proper Mercedes-Benz Key Fob Battery: The Chrome SmartKey® needs one CR2025 battery, while the older SmartKey® style requires two.
• Replacing the Newer Chrome SmartKey®: For the newer style of Chrome SmartKey®, simply pull the tab at the bottom of the fob, remove the casing by pushing the key into the narrow end of the slot, then remove the old battery and replace it with the new battery.
• Replacing the Older SmartKey®: Pelham and Niagara-on-the-Lake drivers with an older SmartKey® will pull the latch at the end of the key fob casing, push the key horizontally into the open slot, then lift the old batteries out of their compartment and set the two new ones in place.

When Should You Change a Mercedes-Benz Key Fob Battery?

It’s no secret when your Mercedes-Benz key fob battery needs replacing. Here are the clear warning signs to watch for:

• You may lose the ability to lock/unlock your doors or activate the panic alarm.
• Your dashboard may display a warning light that alerts you to an issue with the charging system, which could be caused by a dying battery in your key fob.
