When a Mercedes-Benz Key Fob Battery Needs Replacement
There are several warning signs you can look for when you think it might be time to change the battery in your Mercedes-Benz key fob. Initial warnings can include:
- You may notice your vehicle becomes more difficult to start. If it takes several minutes or multiple attempts, that can be an indicator of a low battery.
- If you lose the ability to lock and unlock your doors or set off the panic alarm that can also be a sign your battery is on the way out.
- If you notice a warning sign on your dashboard that indicates an issue with the charging system, that can mean you are losing battery power in your key fob.

Replace Your Mercedes-Benz Key Fob Battery
When it comes time to change the battery in your Mercedes-Benz key fob, there are a few simple steps to follow:
- Determine Your Key Type: Whether you have a newer Chrome SmartKey® or an older SmartKey®, the key type will impact how the batteries will need to be changed.
- Get the Right Batteries: The newer Chrome SmartKey® calls for one CR 2025 battery while the older SmartKey® calls for two.
- SmartKey® for Older Models: To replace the battery in your key fob, pull the latch at the end of the key holder, push your key horizontally into the open slot, and then lift the battery out of the compartment.
- Chrome SmartKey® for Newer Models: Pull the tab at the bottom, remove the cover by pushing the key into the narrow end of the slot then place the battery inside.
