I've read loads of threads on here about central locking issues so thought I'd share what I've learned from extensive google searches.

My central locking was slightly intermittent and then it decided to stop altogether. I didn't have any problems with it locking by itself or the boot opening on its own, but my solution may help these problems. I thought it was my battery so I replaced it, but it still didn't work. I then found this info about resetting/reprogramming the central locking:

Insert key into ignition and turn to ignition and back 4 times in quick succession.
You will then hear a chime which indicates you are in the central locking programming mode.
remove key and press the lock and unlock (although I only needed to press the lock) button on the remote.
You will then here another chime and it should be done.

My central locking works great now with no issues as yet.

Hope it helps, it saved me £45+VAT for a new remote and £68 + VAT my local ford dealer were going to charge me to program it (they probably just use the method given above!). Perhaps this should be a sticky along with info about the central locking fuse and where to find it.

As you say this does seem to be the best idea to clear alot of problems with the central locking,
it makes you think how much money is made by Ford just out of a few minutes work.
I do not know if the same time delay applies for a Ford Focus but battery replacement on Ford Mondeo allows you only 15 seconds to relpace a new battery before the system shuts off from the key
then that would need the same reprograming as you have detailed.
Until the internet started these reprograming details where never known and never able to get hold of.
I bet these main dealers curse these forums now.
Good luck with the car.

Thanks - this worked perfect on my Cmax 2008.[quote name='focustim' date='13 December 2008 - 06:39 PM' timestamp='1229189382' post='8439']
