Is your 2012 Mazda Miata key fob starting to act up? You might be experiencing delayed responses or needing to press the buttons multiple times to lock or unlock your car. The most likely culprit is a dying key fob battery. Fortunately, replacing the battery in your Mazda Miata key fob is a straightforward process you can easily do yourself, saving you time and money compared to a dealership visit. This guide will walk you through each step to quickly and efficiently replace your 2012 Mazda Miata Key Fob Battery and get you back on the road with a fully functional remote.
What You’ll Need to Replace Your Key Fob Battery
Before you begin, gather these simple tools:
- Small flathead screwdriver: An electronics screwdriver or eyeglass repair screwdriver will work perfectly.
- CR1620 Lithium Battery: This is the specific type of battery required for your 2012 Mazda Miata key fob. You can find these at most drug stores, hardware stores, or online retailers.
Step-by-Step Guide to Replacing Your 2012 Mazda Miata Key Fob Battery
Follow these easy steps to replace your key fob battery:
Step 1: Open the Key Fob
Begin by flipping out the actual key blade from your Mazda Miata key fob, as if you were going to insert it into the ignition. This will give you access to the key fob casing.
Step 2: Locate and Open the Notch
Carefully examine the inside of the key recess on the side of the key fob. You’ll find a tiny notch or slot. This is where you’ll insert your small screwdriver to begin opening the case.
Using your small flathead screwdriver, gently press into this notch. Apply a small amount of pressure until you feel the top and bottom halves of the key fob case begin to separate. This action releases the clips holding the two parts together.
Step 3: Separate the Key Fob Halves
With the initial separation achieved, you’ll notice a small rectangular indent, usually at the top of the larger section of the fob. Insert the tip of your screwdriver into this indent.
Apply gentle but firm pressure, pushing in the direction to further split the key fob casing. You may hear a click as the two halves completely separate, revealing the internal components.
Step 4: Replace the Battery
Once the key fob is open, you will see the battery situated on one side of the internal mechanism. Carefully remove the old CR1620 battery. Take note of the orientation of the battery (positive side up) before removing it.
Install the new CR1620 lithium battery, ensuring that the positive (+) side is facing the correct direction, which should be the same as the battery you just removed. Avoid touching the flat surfaces of the battery with your bare fingers, as oils from your skin can reduce battery life.
Step 5: Reassemble and Test
Carefully snap the two halves of the key fob casing back together. Ensure they are firmly closed and all clips are engaged. Flip the key blade back into the fob.
Finally, test your 2012 Mazda Miata key fob to confirm the battery replacement was successful. Press the buttons to lock and unlock your car, and check if the red LED indicator light on the fob illuminates when you press a button.
Conclusion
Replacing the battery in your 2012 Mazda Miata key fob is a quick and easy DIY task that requires minimal tools and can save you a significant amount of money compared to dealership service costs. By following these simple steps, you can ensure your key fob is functioning perfectly and avoid any inconvenience caused by a dead battery. Enjoy the peace of mind knowing you’ve handled this minor maintenance yourself!
