Remote central locking focus 2002 zetec

[gebstar]

Ive got a 2002 ford focus zetec. Problem i have is remote central locking is not working. I have changed the battery and tried reprogramming the key using the turn it on and off 4 times in 3 seconds. I hear a beep but the key doesnt seem to program. The central locking works when i use the key manually. Do you have any suggestions?

you sure it only has 1 battery?

the procedure for reprogramming your key should be in the owners Manual.
