Program New Remote for EL Flalcon

Hoping someone can help.

I am trying to program my Father-in-laws New remote for his EL Falcon.
The Instructions I was given:

sit in the car with door closed,turn the ignition to accesories press the rear demister three times.

after this your doors will lock when this happens press the doors button on your remote the doors will now unlock then lock

this means you remote is now programmed to your car its very easy.

When I press the rear demister three times - nothing happens!

i think u only press it 2 times from memory

you have to press and release the demist button 3 times within 5 seconds door locks should operate to let you know that they are in learn mode. then press the button on remote. locks will operate twice to let you know that it is programmed. sourced info from my car manual for you. hope this helps good luck.
