Why is My 2012 Ford Fiesta Key Fob Not Working?

There are several reasons why your key fob might have stopped working. These range from simple fixes like a dead battery to more complex issues requiring professional assistance. Let’s explore the possibilities.

Dead Key Fob Battery

The most common culprit is a dead key fob battery. Over time, the battery powering your key fob drains, eventually rendering it useless. This is a simple fix and can often be done at home.

Key Fob Programming Issues

Sometimes, the key fob loses its programming and needs to be re-synchronized with your car’s computer. This can happen after a battery change or for seemingly no reason at all.

Faulty Key Fob

If the battery is new and programming isn’t the issue, the key fob itself may be damaged. Internal components can wear out or break, leading to malfunction.

Receiver Issues

The problem may not be with the key fob at all. Your car’s key fob receiver, which picks up the signal from the fob, could be faulty. This requires more in-depth diagnostics.
