Hi Disco Mike,
I did a search on the subjects of door locks and was unable
to find any relating to my particular problem. I havea 1993 Land Rover -Range Rover.
The driver's lock is missing (where you insert the key). I am able to
hold the door handle up and lock all doors using the central lock. So do I
need just the key-housing part?

On yours, you will need to have both a lock actuator and tumbler assembly to get the syste, working. If you have the lock actuator the key look assembly should be asll that is needed.
