Okay so i happen to have lost the keys for my '99 focus and i'm wandering what to do!?

I need a new key with a fob for the remote locking, how can i accomplish this? Also i like the look of the new flip key fobs is there anyway i can use one of them with my ford? I figure if im going to be shelling out for a new key i might aswell get a nice fancy thing

Cheers!
