johnmayerrr Posted August 4, 2023 Share Posted August 4, 2023 Why not just check by opening the keychain? To change the battery, you will need to open it. Quote Link to comment Share on other sites More sharing options...

CelestialSeeker Posted August 4, 2023 Author Share Posted August 4, 2023 Simply by handing over the battery to the auto shop when I drop off the vehicle. Quote Link to comment Share on other sites More sharing options...
NAVITEL Posted August 4, 2023 Share Posted August 4, 2023 Simply request a new battery replacement and be certain that they will have enough on hand as this component is not unique. Quote Link to comment Share on other sites More sharing options...
nimbuye5 Posted August 4, 2023 Share Posted August 4, 2023 Batteries for the remotes are CR2025s. A good brand, such as Duracell or Panasonic, is worth the money. Quote Link to comment Share on other sites More sharing options...
honeycut_mazda5 Posted August 4, 2023 Share Posted August 4, 2023 Whenever I took my vehicle in for a Service B, the mechanics would switch out the battery in the key fob and provide me with a brand new one to install in the spare. Quote Link to comment Share on other sites More sharing options...
