How do I go about getting the original key to my 2010 ford focus to reprogram my car back?. And if so how much is the key?. Thanks Tim.

You will have to go to a Ford dealer. Usually around $100-150 depending if you have to replace the key or not. It will be less if you have the key and remote fob separately versus having the key/remote fob as one unit.

I've found the keyman at my westfield shopping centre has the option to do it too though it's still $200 but will be convenient near my work . I'll need to bring g the car around to the loading dock near him so he can code it
