ZR driver door. Can't get key in lock or open from inside

Have scrolled thru other threads but can't seem to find the answer.



Driver door won't accept the key. Central locking won't open either door. Have to climb thru boot and open passenger door by pulling up button.



The passenger door will lock via fob but not re open and I have to climb in thru boot again



The dashboard locking button sounds ok but does not open or close the doors.



The driver door won't open from inside either. The door button has no effect either. Feels disconnected possibly



Guessing that actuator needs looking at, but how can I get to it as the door needs to be open to remove door card.



Looking in the keyhole, there is a tiny metal part which seems to be stopping the key inserting for manual opening. Outside door handle is a smidge loose too.



Hope someone can help



Thanks.
