This model of Mazda, like other products from 2008 onwards, features the Keyless key, which means you can keep it in your pocket to be recognised by the car, allowing both unlocking and engine starting via the dedicated button. The battery for this type of key is a standard CR 2025 3 Volt, and replacing it is extremely simple.

Start by extracting the metal key (known as the blade) by pressing the release button. Inside the blade housing, there are two small slots to lever and open the remote shell.

At this point, remove the cover beneath which is the battery, taking care with the seal.
