I would locate the fuse in the fuse box and remove the fuse, that's not fixing the problem but it will stop the automatic locking.
All Ford vehicles have a central locking system that were manufactured after 1993. The Ford focus has always had the central locking system.
The number of doors.
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.
one of your doors or bonnet not shut we had the same problem but they will only flash on double locking
if it doesnt work then your keys are jacked up
because your mom broke your car
There are no 2 rear doors.
behind the glove box on passenger side,remove fuse box and central locking fuse is round the back of it.
9 times out of 10 its because of the side door there is a little black switch on the door that pops out when the doors open and back in when its closed this tells the locking system that its not locked so it re opens the doors try uncliping the switch and locking this should work Another problem that causes this is a broken earth wire to the door locking motors both front and the rear doors,it doesnt seem to matter about the side door.
inside the locking unit in the door is a plastic screw jack that breaks. it can be repaired easily if you can trace the part. easy fix Simon
So you don't lock the keys in the car.
Well if you mean the interior lights they automatically switch off when you lock the car doors, if you mean your headlights the dial which turns the headlights on and to park also pulls out and pushes in so you may have it out??
