Mazda CX-5 Key Fob Battery Remote Replacement DIY Years 2013-2019

Heir to the proud lineage that includes the Mazda Tribute and CX-7—the CX-5 is a pioneer of Mazda design philosophy. This compact crossover was born in 2012 and was the first Mazda to feature the KODO – Soul of Motion design language. The concept of this design focuses on recreating the form of an animal that’s ready to pounce—think potential energy. This design philosophy is what sets Mazda apart from the pack and is the reason for the CX-5’s elusive visual style.

Equally stylish is the smart key the vehicle comes with. This key fob allows you to lock, unlock, or panic your Mazda CX-5 remotely. But what’s really “smart” about it, is that you can unlock or start your vehicle while the key is in your pocket. Your CX-5 will detect the proximity of your smart key and grant you access. When your battery dies, simply slide out the handy internal key to get going.

Speaking of your battery dying, let’s get into why your really here—to change the internal battery in your CX-5 key fob! In this guide, we will show you everything you need to know to get your battery changed so you can get back out on the road in no time. Looking for another Mazda key fob?

How to replace the Mazda CX-5 2013, 2014, 2015, 2016, 2017, 2018, 2019 smart key fob battery

This smart key fob can easily be opened to replace the CR2025 battery inside. Scroll down to see a full video tutorial or read on for a step by step guide.

What you will need:
• 1x CR2025 battery
• Flat-head screwdriver

First, flip your smart key over and find the small switch on the back. Push the switch down, and while holding it down, pull on the silver key ring hole to release the internal key. From here, we will need our flat-head screwdriver. Locate the grooves on the left and right walls inside the area the key came from. Insert your screwdriver into a groove and twist to loosen that side. Repeat for the groove on the other side. This will begin to separate the two halves of the key fob.

Now, there should be a separation between the two halves running down the seams on the long sides of the smart key. Insert your screwdriver into these seams, twist, and work your way down each side until you can separate the two halves of the key fob. Inside, you will find a plastic disc, remove it with your fingers to expose the battery. The CR2025 battery can simply be removed with your fingers.

Place your new battery in the compartment with the face up. Put the plastic disc back on top of the battery, click the two halves of the key fob back together, and insert your internal key. That’s it. Battery replaced. Good job!

This is the battery for this CX-5 key fob:
