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

After you’ve opened your key fob, changing the battery is simple. Follow these steps to get the battery changed and you back on your Charleston adventures in no time:

  1. Remove the battery cap to fully expose the battery.
  2. Remove the battery, taking with care with the small rubber ring it sits on. If this gets scratched, it’s important to replace this part before continuing.
  3. If it’s still in good condition, keep the ring in place and put your new battery in the key fob with the positive (+) side up, facing you.
  4. Put the battery cover back on, then reattach both sides of the key fob, pressing down until you hear them click. Then replace the key, and you’ll be all set.
