How to Replace the Key Fob Battery?

While it is possible to replace the key fob battery yourself, failing to do so correctly may permanently damage your key fob. We recommend you take it into to a certified Mazda dealer or similar professional. If you decide to do it yourself, make sure to find a thorough visual guide, as dismantling and reassembling the fob will be the steps that are likely to cause damage. The type of battery you will need is a 3-volt CR2032. You can order one via our online store or from most major retailers.
