How To Replace a Mazda Key Fob Battery

The key fob for your Mazda is designed to make your life easier, as you can easily gain access to your vehicle simply by pressing the key fob when you’re within range of it. But you could find yourself locked out of your car if you don’t respond to signs that your key fob battery is running low. To help you avoid this scenario, our experts here at Sport Mazda South have put together a guide on how to change the battery in a Mazda key fob so it keeps working properly.

Signs Your Mazda Key Fob Battery Is Dying

The most obvious indication that your key fob battery is dying is if it fails to work when you press the unlock button. Luckily, many fobs will give warning signs before things get to this point. For example, you may notice that the range of your key fob decreases, and it only works when you stand close to your car. Another classic sign that the battery lacks the power to function properly is that your key fob may only work intermittently.

Fortunately, replacing a fob battery is a straightforward task that you should be able to perform at home, provided you have the right tools and a spare battery on hand.

How To Identify the Right Battery

The most common types of battery used in Mazda key fobs are CR2025 or CR2032. You can pick these up at a local hardware store or a Mazda dealership’s parts department. These batteries are flat and circular, allowing them to fit snugly into your small key fob.

To learn which type of battery you need, check your owner’s manual for information about the key fob. If you search online, be sure to cross-reference the information you find to ensure its accuracy.

Replacing the Battery

Before you get started with the battery replacement, make sure you have all the tools you’ll need, including the battery, a flat-tipped screwdriver, and a dry cloth. If you don’t have a screwdriver, you may be able to use another key or a knife instead. Then, you can follow these steps to change the battery:

1. Locate the thin slot on the side of your key fob, which is designed to allow you to pry it apart. Put the screwdriver in the slot and twist it until the two halves of your Mazda key fob come apart.
2. Take the battery out carefully and set it aside so you can dispose of it later.
3. Wipe the fob with your cloth to ensure the removal of any dust or debris before you put the new battery in place.
4. Position the new battery in your fob, taking care to have the positive side facing upwards. Avoid touching the contacts with your bare hands, since this can cause a shock.
5. Clip the two halves of your fob back together and test it out.

Throughout these steps, be wary of using too much force when opening the fob or removing the battery. You don’t want to damage the electronics associated with the Mazda key fob battery replacement.

Tips and Troubleshooting

Hopefully, replacing the key fob will resolve your difficulties. If you find that your fob still isn’t working properly after following these steps, there may be another problem with your fob. For instance, electronic issues may prevent it from sending a signal to your vehicle. If you’re unable to get the fob working again after replacing the battery, make an appointment with our  Sport Mazda South service center. You can use our online reservation tool to find a time that fits your busy schedule.
