Opening Your Mazda Key Fob

Whether you want to learn how to open your Mazda6 key fob or your Mazda CX-5 key fob, we can guide you along with ease. The process of replacing a key fob battery is fairly simple and nearly universal for all recent Mazda models. Follow these steps to gain access to your key fob battery:

1. Press the auxiliary key button on the backside of your key fob to remove the metal key.
2. With the metal key removed, you’ll be able to see a slot on either side of the key fob casing.
3. With the tape-wrapped flathead screwdriver, gently pry open the case.
4. This should remove the case, carefully place all the parts in easily-visible spots for access when it’s time to put things back together.

How to Change the Battery in a Mazda Key Fob

Now that you know how to open your Mazda6 key fob, you probably want to pop in a fresh battery to get your Napa commute back on track. The following steps should only take a minute or two to complete:

1. Remove the battery cap and place it next to your key fob case.
2. Your key fob battery should be fully visible at this point. Remove it, but be careful not to damage the rubber ring that it rests on.
3. If the rubber ring is scratched or damaged, it’s important to also replace this component.
4. With the ring in place, set the new battery in the fob. The positive (+) side should sit up, facing you.
5. Replace the battery cover, then reattach both sides of the key fob case. Press until you hear them gently snap into place.
