the door lock issue is simple its the fob hold the lock button down and then with the lock button held press the unlock button for 5 secs now all doors will unlock when the fob is pressed once unlocking door can be as simple as water in the lock remove top torque screw on side of door nearest driver spray wd40 in a down wards 45 degree angle refit the torque screw and try if its still the same give it 20 mins then try again worked on my mk1

After doing this now when I press unlock once the drivers door unlocks only, if I press unlock twice all doors unlock (im assuming its supposed to do this?) but when I press lock once it still only locks the rear passengers door and not any of the others I have to press lock twice.

I will try Jeebowhite's advice later.

Well my problem just changed now when I press the fob once it only locks the rear left hand door and none of the others. If I press it twice all the doors lock ok so I may just accept that I have to live with the issue.

As for your issue Dan do you ever get a noise whilst driving along that sounds like the locking motors are trying to lock? Mine can do that from time to time and when it does I have to manually lock the passenger front door with the key then press the central locking fob and all the doors will lock. From the amount of threads and posts on this issue I think the central locking is a common problem on the Focus.

Have you tried the test function to see if all the door switches are working properly? Sounds like the car thinks a door is open and that why it isn't locking.

here is a link to the procedure http://www.pistonhea...sp?h=0&t=595724

It was just the one door that wouldn't lock/unlock all the others worked fine. If you have checked fuses and wiring maybe its the module for the central locking at fault on yours?
