How to Change a Mazda Key Fob Battery

Opening Your Mazda Key Fob

As you learn how to open your Mazda key fob, you’ll be happy to know that the process is similar for all Mazda models from recent model years. Follow these simple steps to reveal the battery:

  1. Press the auxiliary key button on the back of your key fob in order to remove the metal auxiliary key
  2. With the metal key gone, you’ll notice a slot on either side of the key fob case.
  3. Use the tape-wrapped flathead screwdriver to pry open the case, first on one side, and then on the other. Work gently.
  4. This should remove the case. Place the latter in an easily-visible spot where you won’t lose track of it.

Replacing Your Mazda Key Battery

Now that your Mazda key fob is open, it’s time to reveal and replace your Mazda key battery. This process should only take a moment:

  1. Remove the battery cap, and set it next to your key fob case.
  2. Your Mazda key fob battery should be fully exposed. Remove it, being careful not to damage the small rubber ring that it sits upon.
  3. If you scratched or damaged the rubber ring, it’s important to replace this component before moving on.
  4. With the ring in place, take your new replacement battery and set it in its place in the key fob. The positive (+) side should be up, facing you.
  5. Return the battery cover to its proper place, and then reattach both sides of the key fob case. Press until you hear them click into place.

These steps should work for the most recent Mazda key fob styles, including the mazda3. It’s always recommended you take a look at your owner’s manual to find the battery type your specific Mazda model requires.
