How to change the battery of the key remote for a Mazda CX-5.

Model: Mazda CX-5 MK 2 - Years 2017-2024
Part: Key

Replacing the battery in the remote key for a Mazda CX-5 vehicle requires a few simple steps. Make sure you have a small flathead screwdriver and a CR2025 button battery on hand. Take the remote out of the car and slide the lever located on the back of the casing; this will unlock the metal key inside, allowing you to pull it out by tugging on the upper end of the shell. At this point, insert the tip of the screwdriver into the side edge and pry it open to access the battery compartment. You can then remove and replace the battery.
