2014-2018 Mazda 3 Skyactiv Audio & Electronics
I have a keyless entry Mazda 3. I've had no problems but have just replaced the main and spare key fob batteries (CR2025) as a precaution after two years of use.
The new battery voltage open circuit is 3.2V and both old batteries were down to 2.9V. Does anyone know the minimum battery voltage...
