Is your 2008 Mazda Miata key fob starting to act up? Do you have to press the buttons multiple times, or does it sometimes fail to respond altogether? The most likely culprit is a low battery. Fortunately, replacing the battery in your Mazda Miata key fob is a simple task you can easily do yourself, saving you time and money compared to visiting a dealership. This guide will walk you through each step of replacing your 2008 Mazda Miata key fob battery, ensuring you get your remote working like new again.
What You’ll Need
Before you begin, gather these simple tools:
- Small Electrical Screwdriver: A small flat-head screwdriver, like those used for electronics repair or eyeglasses, will work perfectly.
- CR1620 Lithium Battery: This is the specific type of battery your 2008 Mazda Miata key fob requires. You can find these at most drugstores, hardware stores, and online retailers. Ensure you purchase a CR1620 battery to guarantee compatibility.
Step-by-Step Battery Replacement Guide
Follow these straightforward steps to replace your 2008 Mazda Miata key fob battery:
-
Open the Key Fob: Begin by flipping out the key blade as if you were going to start your car. This will give you access to the internal components of the key fob.
-
Locate and Press the Notch: Look closely inside the key housing where the key blade folds in. You’ll find a small notch or slot. Insert the tip of your small screwdriver into this notch. Gently apply pressure to pry the two halves of the key fob casing apart. You might hear a click as the casing begins to separate.
-
Separate the Key Fob Halves: Once you’ve pressed the notch, carefully pull apart the top and bottom halves of the key fob. They should separate relatively easily. If you encounter resistance, double-check that you’ve applied pressure to the correct notch and try again gently.
-
Access the Battery Compartment: With the key fob separated, you will see the internal components. Locate the battery compartment, which is usually in the larger section of the key fob. You’ll notice a small rectangular indent near the top of this section. Use your screwdriver again to gently press into this indent and push. This action will further split this section, revealing the battery.
-
Remove and Replace the Old Battery: Now you will see the CR1620 battery. Carefully remove the old battery. Take note of the battery’s orientation (positive side up or down) before removing it. Install the new CR1620 battery in the same orientation. Avoid touching the new battery with your bare fingers as oils from your skin can reduce battery life. If you do touch it, wipe it clean with a lint-free cloth.
-
Reassemble the Key Fob: Carefully snap the key fob components back together in the reverse order you took them apart. Ensure all parts are firmly clicked into place.
Testing Your Key Fob
Once reassembled, test your 2008 Mazda Miata key fob to ensure the battery replacement was successful. Press the lock and unlock buttons. You should see the red LED light on the key fob flash, and your car should respond to the commands. If the LED flashes and your car responds, you’ve successfully replaced your 2008 Mazda Miata key fob battery!
By following these simple steps, you’ve saved yourself a potentially expensive trip to the dealership and ensured your 2008 Mazda Miata key fob is working perfectly again. Enjoy the convenience of your fully functional remote!
