Can someone please point me in the right direction, my searches to date have revealed a lot of open ended questions and vague answers

My central locking works fine when using the alarm remote fob to open/close all doors (Microscan Alarm)

If i use the key in the drivers door lock it seems to be turning the internals of the lock barrel (without the whole lock turnign in the handle recess) but nothing happens in terms of physical locking of any of the doors.
The passenger door is worse

- turning the key results in the whole lock assembly turning, and pulling the key out brings the lock out with the key.
Any guidance much appreciated
Whilst the additional security (

) is welcome, i will be knackered if the remote battery goes flat one day :embarassed: :embarassed:
