Reprogramming a new key for 01 sport

I went to the stealership and they want $185 to cut a new key and programm it.

I can purchase they key and have it cut for about $35, but how do
I programm it, so it will turn the ignition on.

Thanks

I also just got a 2001, got a new key cut and tried to program it today, useing a owners manual I got off the net. It dident work. So I think you just have to pay the man and get it done. Let me know if you find out how to do it.

the key has to programmed using Ford's equipment.

had a FORD 2001 explorer key programmed today DEC 2 2004

$31.50 for the key cut at dealership, service manager pal of mine showed me how to do..(FREE)
take all keys to vehicle > insert into ignition > turn ON, but do not start car, so that lights on dash turn ON, insert new cut key last,also turn to ON position > then start...... and it becomes programmed thru the vehicle system.
JOB DONE no need to pay high fees....and no fancy computers used...
