Ford Focus Central Locking Fob Problem.

Hi, Can anybody please help. I have a 2002 ford focus 1800 TDCI. My fob wont work. I replaced the battery & got the fob tested, all ok & the key starts the car. I have tried reprogramming my fob to work the central locking. I get the first noise when i try to programme it, but i dont get the second noise & the light above the clock wont go into learning mode. After many hours looking on net i discovered that it may be GEM fault. I have been told to disconect this & clean it but not sure where it is exactly. It could be behind glove compartment. Can anybody please advise me or tell me what else the problem could be. Thanks in advance.

If you go back to the main page, scroll down to cars, click onto General/Maintenance. There are pages of sound advice, all of which work. This is of course, if your problem is the central locking does not work off the remote.
