If they are like the European Focus then the answer is no.
The car will have an anti-theft immobiliser which interrogates a
transponder inside the key. The replacement key must have such a
transponder and it must be programmed to match your car.
If you have two keys then you can use these to program further keys but
usually people wait until they are down to one key before seeking a
replacement. Only a Ford dealer can supply and program a replacement key
if you only have one key.
Like I said, this is how it works in Europe. It may be different in the
US but from what you say, it doesn't sound like it.

Correct, assuming the original poster has only one key (and given the $100
fee Ford's quoting, this is probably the case). But if the buyer is just
looking to add another key to his existing two keys, then he can program it
himself following the instructions in the owner's manual. I found a spare
key blank on eBay, had them cut (a bit more difficult than for ordinary keys
as many places that cut keys have a policy of not cutting transponder keys),
then programmed it myself.
PS--eBay's also a good source for remote door/trunk lock/unlock devices and
they, too, can be programmed at home.
