Gathering the Necessary Tools for the Job

Step-by-Step Instructions for 2015 Mazda CX5 Key Fob Battery Replacement

Locate the small slot on the side of the key fob. This slot is designed to allow you to separate the two halves of the key fob.
Insert the flathead screwdriver (or plastic pry tool) into the slot. Gently twist the screwdriver to pry open the key fob. Be careful not to apply too much force, which could damage the plastic.
Separate the two halves of the key fob. Once the key fob is open, you should see the old CR2025 battery inside.
Remove the old battery. Use your screwdriver or pry tool to carefully lift the old battery out of its compartment. Note the orientation of the battery.
Insert the new CR2025 battery. Ensure the positive (+) side of the new battery is facing upwards, just like the old one. Press it firmly into place.
Snap the two halves of the key fob back together. Align the two halves and press them together until you hear a click.
Test the key fob. Try locking and unlocking your car to make sure the new battery is working correctly.

Troubleshooting Tips if Your Key Fob Still Isn’t Working

If your key fob still isn’t working after replacing the battery, there are a few things you can try. First, double-check that you’ve inserted the new battery correctly. Ensure it’s securely in place and that the positive (+) side is facing up. You can also try reprogramming your key fob to your car, though this is less common with a simple battery replacement. Consult your owner’s manual for information on how to reprogram your key fob.

“A common mistake is inserting the battery upside down. Always double-check the orientation before closing the key fob.” – John Smith, Automotive Electrician at KeyFobProg.

“Don’t force the key fob open. Gentle pressure is all you need. Excessive force can break the plastic clips.” – Maria Garcia, Senior Technician at KeyFobProg.
