Is your 2012 Mazda MX-5 key fob starting to act up? Do you have to press the buttons multiple times, or has it stopped working altogether? The likely culprit is a dead battery. Don’t rush to the dealership for an expensive replacement. Changing the battery in your Mazda MX-5 key fob is a simple task you can easily do yourself in just a few minutes with minimal tools. This guide from keyfobprog.com will walk you through each step, saving you time and money.
What You’ll Need to Replace Your Key Fob Battery
Before you begin, gather these simple tools and supplies:
- Small Electrical Screwdriver: A small Phillips head or flathead screwdriver will work. Choose one that is typically used for electronics repair or eyeglasses.
- CR1620 Lithium Battery: This is the specific type of battery your 2012 Mazda MX-5 key fob requires. You can find these at most drugstores, hardware stores, or online retailers.
Step-by-Step 2012 Mazda MX-5 Key Fob Battery Replacement Guide
Let’s get started with the battery replacement process. Follow these easy steps:
Step 1: Open the Key Fob
Flip out the key blade on your Mazda MX-5 key fob as if you were going to start the ignition. This will expose the key fob casing and make it easier to access the notch for opening.
Step 2: Locate and Press the Notch
Look closely inside the key recess of the fob. You’ll find a tiny notch or slot. Using your small screwdriver, gently press into this notch. This action is what releases the two halves of the key fob casing.
Step 3: Separate the Key Fob Halves
Once you’ve pressed the notch, the top and bottom parts of the key fob will begin to separate. You should now be able to gently pull the two halves apart completely.
Step 4: Access and Replace the Battery
With the key fob open, you’ll see the battery compartment on one of the halves. You might notice a small rectangular indent near the battery. Press this indent and gently push to further separate the internal components, exposing the battery more clearly. Carefully remove the old CR1620 battery. Take note of the battery’s orientation (+ side up) before removing it. Insert the new CR1620 battery, ensuring it’s placed in the correct orientation. Avoid touching the battery with your bare fingers if possible, as oils can reduce battery life.
Step 5: Reassemble and Test
Carefully snap the two halves of the key fob back together. They should click securely into place. Once reassembled, test your key fob buttons to ensure the red LED indicator light flashes. Try locking and unlocking your 2012 Mazda MX-5 to confirm the new battery is working correctly.
Conclusion: Battery Replacement Complete
Congratulations! You’ve successfully replaced the battery in your 2012 Mazda MX-5 key fob. This simple DIY task can save you a significant amount compared to dealership service costs.
