How Do You Open the MAZDA Key Fob & Change a Dead Battery?

2024 Mazda CX-50 with roof rack and bike rack
 

When you rely on remote start, push button start, or keyless entry technologies to easily get in your Mazda vehicle and hit the road, it can be frustrating when these features stop working on your Corinth commutes. While you can always get help with these problems at your local Denton Mazda service center, you may need to know how to open the Mazda key fob and replace a dead key battery yourself! Before we get started on the instructions, make sure you have the following:

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

 

 

Opening Your MAZDA Key Fob

Whether you’re learning how to open your Mazda6 key fob or your Mazda CX-5 key fob in Lewisville, you can 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

With your Mazda key fob 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 carefully, so you won’t 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.
