Rear N/S door lock does not unlock with remote any more. However, if opened manually from inside by door handle, door unlocks. Door locks with all the others when using remote or dashboard door locking button. Had door card off and squirted lubricant liberally around mechanisms but no joy. Any ideas before I order a locking mechanism and does any one know of a video which shows how to remove it and replace ( can get door card off no problem ).

Sorted. Sourced a secondhand lock of Ebay for £40. Door card off and 30 minutes later, old lock off, new one on and working. Would be quicker if you were a gynaecologist . Old lock had a makers date of 2001 on it so it has come off the very first production model in 2002. Mine is a late 2003 so it must be pot luck if they last or pack in.

glad its sorted..
