How to Change the Battery in Your Mercedes Key Fob

Do you have Mercedes-Benz vehicle with a key fob that’s been malfunctioning lately? The logical explanation may be that the battery is running out. Trust the experts at Kareem Auto Sales Inc and learn how you can tell when your key fob’s battery is dying, and discover how you can replace it yourself.

When a Mercedes Key Fob Battery Needs Replacement

You can tell when your Mercedes key fob battery is dying through a couple of warning signs, which may include:

  • Your vehicle doesn’t start on the first attempt. If you find yourself having to try to start your car again and again before it works, that can be a sign that your battery is low on your key fob.
  • If you attempt to lock or unlock your car’s doors and it isn’t working, that can also mean your battery is dying.
  • If your Mercedes-Benz model shows a charging system warning light on the dashboard, it may be about your key fob’s low battery.

If any of these issues have happened to you, then it’s best to replace your key fob battery sooner rather than later, so you don’t experience any issues when you’re out on Elk Grove or Roseville streets.

How to Replace Your Mercedes-Benz Key Fob Battery

To change your Mercedes key fob battery, you need only follow a few steps:

  • Determine Your Key Type: Some Mercedes-Benz owners may have a Chrome Key while others will have a Smart Key, so figure out which model you have so you can perform the right procedure.
  • Get the Right Batteries: Depending on the key you have, you may need one or two CR 2025 batteries. A Smart Key takes two CR 2025 batteries, while Chrome Keys only need to have one.
  • Smart Key Procedure: If you have a Smart Key, you pull the latch at the end of the key holder, place your key horizontally into the open slot, and open the battery compartment in order to replace them.
  • Chrome Key: To change the battery on a Chrome Key, you pull the tab at the bottom, place the key into the narrow end of the slot to remove the cover, and then replace the batteries.
