All Ford vehicles have a central locking system that were manufactured after 1993. The Ford focus has always had the central locking system.
Under the bonnet there is a fuse bow near the bulkhead. Fuse number 63 is central locking. Its a 20 amp fuse.
Focus owners do not do Volkswagen.
behind the glove box on passenger side,remove fuse box and central locking fuse is round the back of it.
My 2000 SE wagon works in exactly the same manner. I believe that is the way the system was designed.
if it doesnt work then your keys are jacked up

All members of the solar system orbit their respective central bodies in elliptical paths, with the central body at one focus of the ellipse.
You are correct in that the Central Security Module (CSM) is responsible for central locking (Remove trim from above driver's footwell and you'll see the security module mounted above the engine ecu (PCM). It's a small black box with two connectors (one blue, one green). Are there any fault codes stored in the CSM? (Ford > Focus > Security > 1.6 > Petrol > 2000 > 1.6I 16V Zetec-SE > All Codes > CSM ISO) The CSM can be replaced for a used one, no coding needed, just have to add in the remotes (manual process). I got a used CSM off a well-known auction site for less than £15 hoping to cure a fault on my Focus. If you do get hold of a replacement module make sure it has the same functions labelled on the case: RF = Remotes, CL = Central Locking, DL = Double Locking, AL = Alarm Matt Read More: http://www.spsupport.com/index.php/kunena-forum/15-general/2139-2000-focus-central-locking-module#ixzz2S0Aw2aQg
Basically, you cant get there from here. Forget the one programmed central locking keyfob. It has nothing to do with it. Two different systems entirely. The fact that you only have one programmed key is the killer. If you had a second key, then you could program a third yourself. You also cant disable the system yourself. If you want the second key to work, the dealer has to do it using either a WDS, PDS, or NGS scanner.
My friend is having the same problem with her 2011 Focus. They told her it was to do with the traction control kicking in. She said it occurred out of the blue and wasn't under extreme conditions or bad driving. Ford replicated the locking and traction control activation during a test, but they said it wasn't a steering or break issue.
