Changing the battery in your 2016 Mazda 6 key fob is a simple task that can be done at home in minutes. This guide will walk you through the process step-by-step, saving you a trip to the dealership and some cash. We’ll also cover common issues, helpful tips, and answer frequently asked questions.

Why Change Your Key Fob Battery?

A dying key fob battery can manifest in several ways. You might notice a decreased range, meaning you have to be closer to your car for it to unlock. The lock/unlock buttons might become less responsive, requiring multiple presses. In some cases, the key fob might stop working altogether. Regularly changing your key fob battery ensures your Mazda 6 remains accessible and prevents unexpected lockouts.

How to Change the Battery in Your 2016 Mazda 6 Key Fob

Here’s a step-by-step guide to changing the battery in your 2016 Mazda 6 key fob:

Locate the small release button on the side of the key fob. This button is often located near the key ring.
Press the release button and gently slide the metal key out of the fob. Be careful not to force it.
Use the metal key or a small flat-head screwdriver to pry open the key fob casing. Insert the key or screwdriver into the slot where the metal key was located and gently twist. The casing should separate into two halves.
Identify the old battery. It’s typically a small, circular CR2032 battery.
Carefully remove the old battery. You can use your fingernail or a small flat-head screwdriver to pry it loose.
Insert the new CR2032 battery, ensuring the positive (+) side is facing up. Press it firmly into place.
Align the two halves of the key fob casing and snap them back together.
Reinsert the metal key into the key fob.

Common Issues and Troubleshooting

Sometimes, you might encounter a few hiccups during the process. Here are some common issues and how to resolve them:

Key fob still not working after battery replacement: Double-check that the new battery is correctly installed and that it’s a fresh, unexpired CR2032 battery. You might also need to reprogram your key fob to the car, although this is rare after a simple battery change. Consult your owner’s manual for instructions on reprogramming.
Difficult opening the key fob casing: If you’re having trouble prying open the casing, try using a plastic pry tool instead of a metal screwdriver to avoid scratching the key fob.
