Is your 2006 Mazda Miata key fob not working as reliably as it used to? Before you start worrying about expensive replacements or reprogramming, the first and easiest step is to replace the battery. A dead or dying key fob battery is a very common issue, and thankfully, it’s a simple and inexpensive fix for your 2006 Miata, also known as the NC generation MX-5. This guide will walk you through everything you need to know about your 2006 Miata Key Fob Battery.
Identifying the Signs of a Low Key Fob Battery
Just like any battery-powered device, your Miata key fob relies on a healthy battery to function correctly. Here are some common signs that indicate it might be time for a battery replacement:
- Reduced Range: You need to be closer to your Miata for the key fob to lock or unlock the doors.
- Intermittent Operation: The buttons work sometimes, but not always, requiring multiple presses.
- No Response: The key fob completely fails to respond when you press any button.
- Dashboard Warning Light: Some Miata models may display a low key fob battery warning light on the dashboard.
If you’re experiencing any of these issues with your 2006 Miata key fob, replacing the battery is the first and most logical troubleshooting step.
What Battery Does a 2006 Miata Key Fob Take?
The 2006 Mazda Miata key fob, for both standard keys and remote keys, typically uses a CR2025 battery. This is a common 3V lithium coin cell battery that is readily available at most drugstores, supermarkets, auto parts stores, and online retailers. It’s always a good idea to double-check your owner’s manual to confirm the exact battery type for your specific 2006 Miata model, but CR2025 is the standard for this generation.
Step-by-Step Guide to Replacing Your 2006 Miata Key Fob Battery
Replacing the battery in your 2006 Miata key fob is a straightforward process that you can easily do yourself in just a few minutes. Here’s how:
-
Gather Your Tools and Battery: You’ll need a small flathead screwdriver (or a similar thin tool like a butter knife or guitar pick) and a new CR2025 battery.
-
Locate the Notch on Your Key Fob: Examine your Miata key fob. You should see a small notch or slot, usually on the side or bottom of the fob. This is where you’ll insert your flathead screwdriver to open the case.
-
Carefully Pry Open the Key Fob: Insert the tip of your flathead screwdriver into the notch and gently twist. This should start to separate the two halves of the key fob case. Be careful not to apply too much force, as you don’t want to damage the plastic casing.

Open the Key Fob Case: Once you’ve created a small opening, you can usually use your fingers or the screwdriver to carefully separate the two halves of the key fob case completely.
-
Identify the Battery: Inside the key fob, you’ll see the CR2025 battery. Take note of the battery’s orientation (+ side up or down) before removing it.
-
Remove the Old Battery: Gently pry out the old CR2025 battery. You can use your fingertip or the flathead screwdriver to help with this.
-
Insert the New Battery: Place the new CR2025 battery into the battery compartment, ensuring it’s oriented the same way as the old battery (usually with the positive (+) side facing up).
-
Reassemble the Key Fob: Carefully snap the two halves of the key fob case back together until they are securely closed. You should hear a click or feel them snap into place.
-
Test Your Key Fob: Try using your key fob to lock and unlock your 2006 Miata. It should now be working with a fresh battery.
What if a New Battery Doesn’t Fix the Problem?
If you’ve replaced the battery in your 2006 Miata key fob and it’s still not working correctly, there might be a different issue. Some possibilities include:
- Key Fob Programming: Occasionally, the key fob may lose its programming and need to be reprogrammed to your vehicle. This is less common with simple battery changes but can happen.
- Key Fob Damage: The key fob itself might be damaged internally due to drops, moisture, or wear and tear.
- Vehicle Issues: In rare cases, the problem might not be with the key fob at all, but with the vehicle’s receiver or security system.
If a new battery doesn’t solve the problem, it’s recommended to consult with a qualified automotive locksmith or your local Mazda dealer. They can diagnose the issue and provide further solutions, which may include reprogramming, key fob replacement, or addressing potential vehicle issues.
Replacing the battery in your 2006 Miata key fob is a simple and cost-effective first step in troubleshooting key fob problems. By following this guide, you can ensure your key fob is powered up and working reliably, keeping you securely connected to your beloved MX-5.
