Doesnt look like they are able to supply the blank key for a FIAT free, look at there list its a different one to what the actual locking bit will work with.
The free blanks we do are those listed on our eBay page, Please, advice which one you wish to receive or non. These are the only free blanks we have. Sounds like they might have other non free ones if you contact them. I dont know if you could use the key bit from your original ones.
The immobilizer transponder chip has to be stuck into our handheld transmitters (remote controls) (above the LED). (i.e. If your existing key has chip inside, some can transfer their chip into our remotes! and save 100’s £££) If you get the fiat key then it should work only if you can do the above, i'm not sure what that means it may mean cutting into your key if its sealed to get at the chip inside.
I think i'd be happy with a fob and keep my original key, yes having it as 1 unit is great (volvo s40) key is so nice to have in my pocket, but would you be able to say 100% you'd trust it at 3am when its cold dark and wet and your stuck in town.
