You can replace the remote control battery of the Mazda 3 by pressing the appropriate button on the remote, allowing the key blade to be lifted: once it is lifted, use a screwdriver to pry inside its housing. The remote control cover can be completely detached to access the battery underneath: this can now be removed from its seat to insert the new one. Now, secure it with the remote control panel, then close the key blade.
