Reprogramming Key Fob Problem

[Wimpy1981]

I have been unable to use the remote central locking on my car (Focus LX '05) since I changed the battery in my key fob.

Following the instructions in the manual on how to reprogram the key, When I press the button on the key during the learning mode I should get a 2nd beep to indicate the key has been accepted, which I do but the central locking still doesn't work. Surely this must indicate that the key fob transmitter is working and the key has been accepted so I'm at loss on what the problem could be.

Any ideas?

Thanks.
