LX, Zetec and Ghia all do though. You will need to buy a remote key and a blank blade for it.

You're looking at around £6 - £8 for a locksmith to cut your new key based on the code they can depict from your current one.

Once you have one working keyblade and one cut-but-not-coded-remote key you need to go to Ford or anybody who has the same tech as a Ford dealer (a Ford specialist garage probably) who will then need to recode your 2 keys and your car all to each other..............this unfortunately is the expensive bit and the only bit you absolutely cannot get away without doing.

Once you have 2 fully coded keys you can purchase more remote keys (Jaguar flip keys work as well as I have converted one as to work with my Focus) and blank blades and have up to 10 keys coded to your car - all of which you can do yourself.

Silly question - can you not go back to whoever you bought the car from and ask them to find the remote key? Would save yourself around £100!
