When a Mercedes-Benz Key Fob Battery Needs Replacement

Knowing when to change your Mercedes-Benz key fob battery can appear in several ways. That’s why you may want to start looking for a replacement if you notice any of these vehicle issues:

• Difficulty Starting: If it takes several minutes or multiple attempts, that can be an indicator of a low battery.
• Unable to Lock/Unlock Doors: If you can’t lock and unlock your doors or set off the panic alarm, this can also be a sign your battery needs to be replaced.
• Flashing Warning Sign: A warning sign on your dashboard can indicate an issue with the charging system and let you know if you’re losing battery power in your key fob.

Replace Your Mercedes-Benz Key Fob Battery

Once you’re ready to replace your Mercedes-Benz key fob battery, follow these simple steps:

• 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.
