The doors on our bathrooms have nice mortise locks with holes for "skelaton keys". Of course, the keys are long gone :)
Since this is a bathroom, I would like to replace the key access with a knob on the inside (and perhaps just an allen key hole on the outside for access in emergencies). i.e. I would like to use the original mortise box but now have it activated by turning a knob rather than inserting a skelaton key.
Is it DIY practical to convert a skelaton key mechanism to a turn knob? If so, where can one find the knob.
Thanks, Jeff
