If this is really the primary key then you shouldn't use a key which is already in the table, after all, this is what primary keys are used for.

What Dave told you is also good because you should have a mecanism of assigning primary key like using a TABLE.DBF to act as a data dictionary which can then be used to know the next value of the primary key and for the locking mecanism.
