driver door issues

hi ive got a 03 fabia 1.9 sti.lately the drivers door has been playing  up its been locking the door but the imobiliser hasn't been flashing or if you press the open button on the fob it open all the doors bar the drivers which you have to open manually from inside.Now yesterday I locked it with the fob and it wouldn't do either the imobiliser came on but  the car wouldn't open from the inside or the outside.i am currntlt getting in and out my car via the passenger door (noy a good look).
