How to Replace the Battery in Your 2018 Mazda MX-5 Key Fob
Replacing the battery in your 2018 Mazda MX-5 key fob is a simple task you can easily handle at home. Here’s a step-by-step guide:
- Locate the Release Button: On the back of your key fob, find the small release button.
- Separate the Key Fob: Using a small flat-head screwdriver or your fingernail, gently press the release button and separate the two halves of the key fob.
- Remove the Old Battery: Carefully pry out the old CR2025 battery from its slot. Avoid using excessive force to prevent damage.
- Insert the New Battery: Place the new CR2025 battery in the slot, making sure the positive (+) side faces up.
- Reassemble the Key Fob: Align the two halves of the key fob and press them together firmly until you hear a click.

Troubleshooting Common Key Fob Issues
