Recognizing a Dying Key Fob Battery

Before you start digging for a new battery, let’s make sure that’s really the problem. Here are a few telltale signs that your 2018 Ford Mustang GT key fob battery might be on its last legs:

Decreased Range: Do you find yourself having to stand closer to your car to lock or unlock it? This could mean your key fob battery is losing power and its signal is weakening.
Inconsistent Response: Does your car sometimes respond to your key fob, and sometimes not, even when you’re within a reasonable distance? This inconsistency is another strong indicator of a failing battery.
Dashboard Warning: Keep an eye out for a “Key Fob Battery Low” warning on your dashboard. This is your car’s way of giving you a heads up that a replacement is in order.
