Diagnosing Your 2016 Mazda 3 Key Fob Battery Issue

Before you rush to replace the battery, it’s crucial to ensure that’s the actual problem.

Trying a spare key fob, if you have one, can help isolate the issue. If the spare key fob works flawlessly, the problem is likely with the original key fob’s battery or the fob itself.

Is it the Key Fob or the Car?
