Ford Remote Start Not Working After Battery Change

If you recently changed the battery in your vehicle and the remote start is no longer working, it could be because the new battery has reset your key fob’s pairing code. Your car’s electronic system does not recognize the new code and thus refuses to start when instructed by a signal from the key fob. The easiest solution is to reprogram your key fob.

You’ll need access to your owner’s manual or an online guide for instructions specific to your model of Ford vehicle. Generally, all that is needed is pressing certain buttons on both the transmitter (key fob) as well as inside your car at once in order to re-establish communication between them.

The process only takes a few minutes, but it will ensure that all of its features are functioning properly again.

If you need help resetting or programming your key fob, contact a local Ford dealership for assistance.
