Hi to all

I have a space star 02 1.3 petrol one of my keys have come part from the head and I got a blank key from the garage and got it cut. They told me that the one that will cut the key for me will be able to program the key. the ones that cut the key told me the key already has a code and it will have to be programed in to the car.

I would like to know if this is so and how to do it as I do not trust the garage where I got the blank key from as they f*** up my own car radio before and they said it was like that when I brough in the car and it was not.
