hey iv noticed how alot of people r wondering how to program a key for ford falcon el well this is how the true way cause i just did it and had to work it out for myself
sit in car with doors closed but unlocked
turn the key to acc, within 5 sec
push the demister button 3 times and push the unlock door button on the car
wait a second doors should lock then unlock by themselves
push button on remote
doors should operate
then turn key off
doors should operate again
then your key is programed
(remember to push door unlock/lock button inside car after the demister)

this does work if have any problems email me at dubvegas_knight@hotmail.com

hope this helps people.
