Ford Owners Club - Ford Forums > Ford Models > Ford Mondeo Club
Ok here's a strange one, my 2001 mondeo,car is left running window undone ( luckily ) doors lock themselves !???????? Also the fob key doesn't start the car, but the other key does, any ideas please. ANdy t
The doors locking themselves is usually water in the door locking motors causing a short.
The key not working sounds like an un-programmed or broken transponder chip.
Stoney your a hive of information, why do I have 2 keys tho, the second key is just a key on its on with the chip, obviously the previous owner had probs with the main key( fob) and got an ordinary key,,,,, so I need to fix or replace the main fob key yes...where will I find the door locking motors stoney, is it door panels off??? Thank you for you quick reply. ANdy
Usually the cars are sold with one remote key and one standard transponder only key.
On cars before 2003/2004 it used to be possible to add extra keys yourself as long as you had your original two keys to enable a learning cycle.
Ford removed that ability after then so you would have to get someone with a VCM/IDS system to add keys via the data port.

I have two rules when it comes to a Ford, don't buy one with only one key and if you get one with both keys then source a third spare key as soon as possible for daily use.
Concerning the door lock motors, it's panel off I'm afraid.
Spraying WD40 into any gap around the lock mechanism may help but you tend to find that rust and gunk build up on the lock solenoids and actuator mechanisms.
Water gets past perished window seals and works it's way down into the door innards causing all manner of trouble.
