Mazda 5 Key Fob Battery Remote Replacement DIY Years 2006-2015

The Mazda5 has been sold by Mazda since 2004. This model is actually the second generation of the Mazda Premacy, rebranded for non-Japanese markets. Considered a mini-minivan in the U.S., a compact MPV in Europe, and sold officially as a mid-size wagon by Mazda, this vehicle is clearly difficult to classify. It packs 3 rows of seats into its small footprint and features mini-van style sliding rear doors. Though the vehicle was favorably rated and popular in many markets, it was eventually discontinued in 2018.

The Mazda 5 uses Mazda’s “flip” key fob. This device allows drivers to lock, unlock, panic, and open the hatch of their vehicle remotely. Additionally, the device has a flip-out internal key. If your key fob has run out of battery, don’t worry. DIY battery replacement for this key is simple and can be done easily at home. Here, you will find everything you need to change the battery in your Mazda 5 key fob. Looking for a different Mazda key fob?

Begin by pressing the button on the face of your key fob to flip out the internal key. Next, locate the seam on the top of the compartment where the key was housed. Hold the top of the fob (where the metal button is) and use a flat-head screwdriver to push up against the seam to separate the two halves of the device.

Now, look to the bottom of the key fob where the keyring attaches. Insert your flat-head screwdriver into the opening you made and twist, until the face of the device comes completely off. You now have access to the battery.

Next, hold the device with the extended key facing down and insert your precision screwdriver (or another thin tool) into the bottom-right corner of the compartment that houses the battery (there is a small black arrow pointing towards it). Use a prying and rocking motion to pull the battery up until it pops out.

Take your replacement CR1620 battery and put it face down into the compartment. Position the top side of the battery first, getting that into place before pushing on the bottom of the battery to click it into place. Finally, put the two pieces of the key fob back together. All done—you just replaced your Mazda 5 key fob battery!

In this video, I'll show you how to change the battery on your Mazda 5 key Fob. This particular Fob was used on the Mazda 5 for models between 2006 and 2015. Inside, we're going to replace place a CR 1620 battery. Just follow along and you'll get your battery in there in no time. Flip this out first and looking in that compartment where the key just was, see where the light is reflecting off of that.

That's a little groove that we're going to push off of. As you can see, once you start to move it, this whole top plastic part is going to come right off. So you can just continue pushing and then start working from the bottom. But if yours a little too tight and it doesn't come easily with your fingers, grab a tool like a flathead screwdriver. Hold the top here, because this is not going to move.

This is going to come up. So you don't want to hold this part, hold the top and find that group and push. Just push right up on it and it'll come straight off. Or once you have a little separation, come in the bottom just with a little twist, you can really safely remove that part to get access to the battery from here. I'm going to use a precision screwdriver to remove the battery because it's in there pretty deep.

This is just a cheap set of precision screwdrivers you can get for a couple dollars on Amazon. I'll leave a link if you want to get one of these. You can use a pen or a toothpick or something. But I think it's safer and kind of easier with one of these. But no matter what you have, we're going to go to the with the key phasing down.

We're going to go to the bottom right corner here, where there's this little arrow and insert our tool almost to the bottom and start just trying to pry out the battery, just rocking it. And there we go. We loosened it up again in that corner and just rocking and prying, and it will pop right out. Once you have your replacement CR 1620, make sure the face of the battery that has the brand information goes down into this part and you will just slide in the top. So this top part goes into its place, and then you push on the bottom.

It clicks securely into place.

And now just lining everything up and pushing it back in.

We're done. We're good to go. You have a new battery in there and you're ready to go for a drive. So thanks for watching.
