How to Open the Mazda Key Fob

Hand Holding Key FobAs a driver with access to the Mazda key fob, it’s easy to rely on the conveniences it provides like remote start, push button start, and keyless entry. Once these features stop working, you’ll want to replace the battery as soon as possible. If you’re unsure on how to do that, or just want someone at our service center to show you how to open the Mazda key fob and replace a dead key battery yourself, feel free to contact our service department. But know before you get started, you’ll need:

  1. A replacement battery on hand (CR2025 battery)
  2. Your Mazda key fob
  3. A small flat head screwdriver with the head wrapped in tape to prevent scratches

Opening Your Mazda Key Fob

Whether you have a Mazda6 key fob or Mazda CX-5 key fob, you’ll be glad to know the process is similar for all Mazda models from recent model years. These are the steps you’ll need to follow to reveal the battery in your key fob:

  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

Once your Mazda key fob is open, you can easily replace your Mazda key battery. This process won’t take too long to complete. Simply follow these steps and get back onto St. Jacob roads in no time:

  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.
