Create a unique or primary key constraint.

The best way I ever found of enforcing this was to create a record group, and add/remove the key value to the group as you create/delete records.
This allows you to check for the key value already existing before you create a new record.

Remember that this solution only works for a single user. You do need to use a primary key when there are multiple users.
