Has anyone bought a replacement key which has  to be reprogrammed with the existing code?  if so how was it carried out * how easy it to do yourself ?

I've not done one for a Fusion, but did one for a Puma just by following the procedure in the Owner'sHandbook, it took me a couple of goes but was successful in the end.

how many working keys have you got (not including the new one). My understanding is that if you have two then you can program a third one quite simply. if you don't have two then it needs more specialist stuff. I did one on a 2008 focus using a good OBD fault code reader (about £20) and (free) Forscan software on a Windows laptop.  Or you could go somewhere like Timpsons and pay about a hundred quid, but not many people would want to do that.

I had a focus that needed a new key as the old one was worn out. I zip tied the old key under the ignition barrel to sort the coding out and then got a  New key made for pennies...all new keys now don't need programmed and cost pennies.

 

"I had a focus that needed a new key as the old one was worn out.

Also, on ebay , you can get new keys cut from a photo of a key. I got one done and it was fine

All fine unless the insurance company finds out though.
