If you’re experiencing issues with your Mazda MX5 key fob, like unresponsive locking or unlocking, a dying battery might be the culprit. Luckily, replacing the Mazda MX5 key fob battery is a simple task you can easily tackle at home. This comprehensive guide will walk you through the process, providing all the information you need to get your key fob back in perfect working order.
Understanding Your Mazda MX5 Key Fob

- Key Fob Battery: This battery powers the remote locking/unlocking and panic functions of your key fob.
- Smart Key Battery: Found in newer Mazda MX5 models, this battery is responsible for the proximity keyless entry and push-button start features.
This guide will primarily focus on replacing the key fob battery.
Gathering Your Tools
You only need a few tools to replace your Mazda MX5 key fob battery:
- A small flat-head screwdriver
- A fresh CR2032 battery (This is the most common type for Mazda key fobs, but check your owner’s manual to be sure)

Step-by-Step Guide to Replace Your Mazda MX5 Key Fob Battery
Replacing the battery in your Mazda MX5 key fob is a straightforward process:
- Locate the notch on the side of your key fob. This is usually located where the metal key part is attached.
- Carefully insert the flat-head screwdriver into the notch and gently pry open the key fob. Be careful not to use excessive force, as this could damage the casing.
- Once the key fob is open, locate the battery compartment. This is usually a small, separate compartment within the fob.
- Gently remove the old battery. Take note of its orientation, as you’ll need to insert the new battery in the same way.
- Insert the new CR2032 battery into the compartment, ensuring the positive (+) side faces up.
- Align the two halves of the key fob and press them firmly together until you hear a click. This indicates the fob is securely closed.

Testing Your New Battery
After replacing the battery, test all the functions of your key fob to ensure it’s working correctly:
- Lock and unlock your car doors.
- Test the panic button.
- If your Mazda MX5 has a push-button start, try starting the engine using the key fob.
If any of these functions are not working, double-check that the new battery is properly installed and that the terminals are clean.
What if My Key Fob Still Doesn’t Work?
If you’ve replaced the battery and your Mazda MX5 key fob is still not working correctly, there could be other issues at play, such as:
- Faulty Key Fob: In some cases, the key fob itself may be malfunctioning and require replacement.
- Programming Issues: The new battery may need to be programmed to your specific vehicle.
If you suspect either of these issues, it’s best to consult with a qualified automotive locksmith or your local Mazda dealership.
