As a company that prides itself on its next-generation designs and technology, the Advanced Keyless Entry system is a staple among current Mazda vehicles. With it, you can do many things with just the single press of a button. But what happens when the battery runs out? Check out a step-by-step guide on how to replace the battery in a 2020 Mazda CX-5, courtesy of Bob Baker Mazda.

What You Need

When replacing the Mazda CX-5 key battery, you will need a few items. This includes a CR2025 battery or equivalent to place into the key fob, a tape-wrapped flathead screwdriver or equivalent tool with a softer tip, and a clean space to place your key fob parts to ensure they don’t go missing during the process.

Step-By-Step Process

1. Press the small knob and pull out the auxiliary key.
2. Twist a tape-wrapped flathead screwdriver (or flat, soft-tipped item) into the small side space to gently pry open.
3. Insert your tool into the outer gap and slide it along the opening. Twist to remove the cover.
4. Remove the battery cap and battery. Make sure the rubber ring is not damaged or detached. If it detaches, reattach it before placing in a new battery.
5. Insert a new battery with the positive pole facing up. Cover the battery with the battery cap.
6. Close the cover. Re-insert the auxiliary key.

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.
