If you're looking to pick up a new key fob, or repair one, you might wonder how long programming it takes and whether or not you can do it yourself.

Remotely revving the engine with the key fob might appease enthusiasts or annoy neighbors, but the new function is part of the Mustang's key milestones.

Key fobs are pretty standard ways to lock and unlock your car, but some key fobs do a whole lot more than just manipulating doors and starting your car.

Rather than having to get in and start the car in order to rev it, the Mustang's new "Remote Rev" feature will let you do it from a key fob.
