Owning a 2018 Mazda CX-5 is a joy, until that dreaded moment your key fob stops working.

This article will guide you through everything you need to know about your 2018 Mazda CX-5 key fob battery, from identifying the right type to replacing it yourself.
What kind of battery does a 2018 Mazda CX-5 key fob take?
The 2018 Mazda CX-5 key fob uses a CR2032 battery, a common type of lithium coin battery found in many electronics. You can find them at most hardware stores, auto parts stores, and even online retailers.
How do I know if my key fob battery is dead?
Several tell-tale signs indicate a dying key fob battery:
- Decreased Range: You find yourself having to stand closer to your CX-5 to lock or unlock the doors.
- Intermittent Functionality: The key fob works sometimes, but not others, or requires multiple button presses.
- Dashboard Warning Light: Your CX-5 may display a warning message indicating a low key fob battery.
How to change the battery in a 2018 Mazda CX-5 key fob?
Replacing the battery in your 2018 Mazda CX-5 key fob is a straightforward process:
- Locate the release button: On the back of your key fob, find the small, recessed button.
- Release the key blade: Press the release button and gently slide the metal key blade out of the fob.
- Open the fob casing: Use the tip of the key blade or a small flat-head screwdriver to carefully pry open the fob casing at the seam.
- Replace the battery: Gently remove the old CR2032 battery and install the new one, ensuring the positive (+) side is facing up.
- Reassemble the fob: Align the two halves of the fob casing and press them together firmly until you hear a click.
- Reinsert the key blade: Slide the key blade back into the fob until it locks into place.
Can I drive my Mazda CX-5 with a dead key fob battery?
Yes, but with limitations. While you can’t start your CX-5 with a dead key fob battery, you can still use it to unlock the doors and start the engine using the following method:
- Unlock the driver’s side door: Hold the physical key blade against the sensor located on the driver’s side door handle to unlock it.
- Start the engine: With the key fob inside the vehicle, place it in the designated slot in the center console. Then, press the brake pedal and push the engine start/stop button.
Tips for extending your Mazda CX-5 key fob battery life:
- Avoid frequent button presses: Only press the buttons on your key fob when necessary.
- Keep your key fob away from extreme temperatures: Heat and cold can shorten battery life.
- Don’t let the battery drain completely: Replace your key fob battery as soon as you notice any signs of weakness.
