both passenger window and lock stopped working. you hear a "click" when using the central console unlock/window down, but nothing happens on passenger side. drivers side door lock still works fine (already replaced window motor around same time!) Manually able to open passenger door from inside car.

pax door locks with remote, wont unlock. drivers side works properly.
got out of car to replenish washer bottle car still running passenger for shut and drivers door fortunately not fully shut but on catch. After shutting bonnet tried to get into car and the central locking had activated with car running and me outside. managed to get a long cane between top of window and roof and toggle the door lock switch on panel below radio. Passenger door opened not drivers but it enable us to get in.
what causes this?????

The right door of 2005 mini could not be opened from the inside but had to be opened manually from the outside. Also, you could lock the door using the key fob.This problem apparently came about after a passenger had tried to let himself out and was not aware of the correct operation of the door.

Yup, my FOB seems to work and it sounds like it unlocks the doors, however the driver's side door needs to be unlocked manually. And the passenger's side door fails to unlock at all.

I purchased this car in 2005 with about 3.000 miles on it. I have replaced window motors 3 times, power steering (reimbursed by Mini, but had to drive from Tahoe to Southern Oregon without power steering)and now the driver side door won't unlock with key faub or interior door lock switch. The driver side door locks with key faub, but not with interior door lock switch. I love this car and for the most part it has been a great car. This however, is a major safety issue.

Driver side door will not lock with FOB or manually. When pressing the lock down physically it pops back up as if the key was still in the ignition as a safeguard preventing you from locking your keys in the car.
