Ford Mondeo rear near side door locked shut and central locking not working

when you try to operate central locking with key in door does the other doors try to unlock

No the central locking does not open the other doors at all.

Sorry the key does not try to operate the central locking when inserted into the front doors on either side plus I've tried disconecting the car battery for 10 mins no luck and also disconecting both car door plug leads with no luck as well. matb

check the fuses if o.k. by the passenger front footwell there is a panel on the left below the glove box remove this and check the wiring as i had came across similar problem and the wiring had corroded

sounds like the battery on the car is flat try jump leads or another battery but if the light on the dash flashes with the ignition on then it has an immobilser fault.if you let the light flash with ignition on it should stop after one minute then flash out a 2 digit fault code ie 3 times then two means code 32 then it repeats 32 32

Hi lombard11 just got around to checking the fuses as its been a busy weekend and you were right the central locking fuse had blown. So swapped it for the fog lights fuse to check out the system and hey presto central locking is working and the light on the clock / dash has gone out. Great only problem is I've noticed the following in the car manual it lists a 30amp fuse for the fog lights but in the fuse box and on the fuse box diagram it shows a 20amp fuse. Although the 20amp fog light fuse has not blown which is correct?
