Signs Of A Dying Mazda Key Fob Battery
Its not hard to notice when your key fob is starting to have problems, but we use them so often, sometimes we neglect the obvious.
- More clicks than usual: You may not notice it because sometimes we might just click and click until what we want to happens does. But if you notice you have to click X amount of times more than what is recommended, then thats a good sign that the key fob battery is wearing down.
- Doesnt work consistently: There might be times when the key fob doesnt want to work for you, and you think to yourself, thats odd, but it probably isnt as odd as you think. Its probably your battery struggling to work, and if you dont get it fixed, it will die completely.
- Signal strength is not as good: There might have been a time when you could start your car from across the parking lot or further, and now you have to be right on top of it to unlock the doors and start the engine. This is a common Mazda key fob battery loss problem.
- Dashboard Warning: Your dashboard pops up a lot of different warnings and cue-ins, but if your key fob is dying on most cars, it will let you know on the dashboard. Its easy to ignore these dashboard warnings, but they are there for a reason.
