When a Mercedes-Benz Key Fob Battery Needs Replacement

If you think it might be time to change the battery in your Mercedes-Benz key fob, there are a few warning signs that can confirm your suspicions. Initial warning signs can include:

  • Your vehicle is more difficult to start. If your battery is getting low, it can take multiple attempts or up to a few minutes to get your vehicle going.
  • If you find you’re no longer able to lock or unlock your doors, and can’t set off the panic alarm, then it is time to try replacing your battery.
  • If an illuminated warning sign on your dashboard that indicates an issue with the charging system appears, that can mean you’re losing battery power in your key fob.

Once you experience any of these warning signs, it’s time to take the proactive step to change the battery in your Mercedes-Benz key fob. This can prevent further issues when you’re on the go in Clarksburg.

Replace Your Mercedes-Benz Key Fob Battery

To change the battery in your Mercedes-Benz key fob, there are only a few simple steps you need to follow:

  • Determine Your Key Type: Whether you have a Chrome Key or a SmartKey® will impact how the battery is changed.
  • Get the Right Batteries: You will need two CR 2025 batteries for the SmartKey®, while the newer Chrome Key only needs one.
  • SmartKey®: For the SmartKey®, pull the latch at the end of the key holder, stick your key horizontally into the open slot, and lift the battery compartment out to replace the batteries.
  • Chrome Key: When changing a Chrome Key battery, pull on the tab at the bottom, push the key into the narrow end of the slot to remove the cover, and replace the battery.
