How Do You Change the Mazda Key Fob Battery?

Dashboard Mazda

It’s not uncommon for West Columbia or Irmo drivers to get accustomed to the remote access of their new Mazda vehicles, whether that means remote starting the vehicle or locking the doors from a distance. It can be very convenient, but when the battery in the key fob dies, you’ll have some trouble with the remote technology until you replace the battery. Luckily, we at Mazda of Columbia can teach you how to open your key fob and replace the CR2025 battery yourself.

How to Open Mazda Key Fob

  1. On the back of your key fob, there’s an auxiliary key button. Press that button to remove the metal auxiliary key.
  2. When the metal key is out, you’ll see a slot on either side of the key casing.
  3. Use a tape-wrapped flathead screwdriver to carefully pry open the case. Gently start on one side and then move to the other side.

How to Change Battery in Mazda Key Fob

Once the key fob is opened, it’ll only take a few moments to change out the battery and get back on the Lexington roads. Follow these steps to replace the battery:

  1. Remove the battery cap to expose the battery.
  2. Take the battery out, and be mindful of the small rubber ring underneath. If scratched, you’ll want to replace it before continuing.
  3. Be sure to keep the ring in place and put the new battery in the key fob with the positive (+) side facing up.
  4. Place the battery cover back in, then reattach the sides of the key fob. Be sure to press them down until you hear a click.
  5. Replace the key and you’re ready to go.
