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.

If you experience any of these warning signs take the proactive step to change the battery in your Mercedes-Benz key fob to prevent further issues when on the road in West Bloomfield.

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: You may have either a Chrome Key or a Smart Key, and that impacts how the batteries are changed.
  • Get the Right Batteries: A Smart Key needs two CR 2025 batteries while the newer Chrome Key only needs one.
  • Smart Key: For the Smart Key, 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.
