Hi, I have 1999 mondeo ghia x.
Central locking works fine using fob.
But when using key in the door lock, central locking only works when it's really warm.
Took door card off and pulled the multiplug from the bottom of the door lock. Didn't look dirty however 20 mins with a dremel and electrical contact cleaner cleaning up the contacts, both male and female, and put it back together and everything works perfectly.
However a few days later it returns to its not working state.
Been through this process several times on both driver and passenger doors.
Always the same, works perfectly but only for a few days.
Am I missing something or doing something wrong.
It's not major but is very frustrating.
Any advise welcome

I have the same problem but only in the winter, it doesn't open any doors bellow like - 5 degrees Celsius.... I only have a key and not a remote. There should be a problem with the locking system (where you put the key in). There is no electrical problem, because you use the key fob and it opens the doors, so you need to check the door lock, unmount it, there should be some metal contacts that are dirty and that's why it won't open the car doors! Hope you understood what I wanted to say!

OK thanks for that. Will have a look next time I'm in there.
Fingers crossed.

Been a while but recently spent some time fiddling with the lock based on what previous poster said.
I tried not to unmount the door lock itself as having changed one a few years ago I found the little clips and rods VERY fiddly so tried to bend a wd40 straw "round the back" and spray. This did nothing.
Last chance was to spray through the front of the lock with the door open. There are some small gaps where the catch sits. So emptied a lot of wd40 on a "hit and hope" plan.
One week later and the central locking is still off the key.
Maybe got lucky but thanks again for the heads up from previous poster
