How Long Should the Key Fob Battery Serve Your Mazda?

By now, you understand the frustration that comes with having a key fob with a flat battery. Therefore, after the replacement, many Mazda owners are always asking how long the new battery is going to serve their remote.

The battery in your Mazda key fob is designed to last long enough. As per the product descriptions, the battery isn’t supposed to run for not less than three years. It’s for this reason that most people end up forgetting that the battery ever existed. Luckily the remotes have a warning light to tell you when the battery is about to go flat.

How Can You Tell If the Key Fob or Its Battery About to Die?

There is nothing that feels bossy than opening the doors of your Mazda from a far distance. That’s one thing that makes many people feel awful when the gadget starts to misbehave.

There are many ways to tell if the fob or its battery is about to die. The signal strength of your fob remote reduces as the battery in the remote drains its charge. Therefore, if you used to enjoy opening the door from a distance of about 50 feet, you will notice the range reduce.

You don’t have to wait until you have to be next to the car for the door for the remote to work. By doing so, you will have lost the purpose of the remote, which is enjoying the long distance. Another thing that you should consider is the number of times you need to press the open button, for example, for the doors to respond.

Immediately, you install the new battery; you will notice that you only need a single press on the button for the doors to open. However, the quick response reduces with time. You don’t have to ignore the case until when you need to press that button up to five times for it to respond.

The experts at Mazda are always against drivers allowing the batteries to wear out completely. By doing so, they end up resetting the remote fob sensor and hence messing with the connection with your specific car.
