A change in key collection calls for a fresh check. When matching the key count, the vehicle VIN, and the handover signature, do not fill a gap with records from a similar model or a neighboring order. Mark the key collection record complete only after ruling out a mismatch caused by keys and vehicles being handed over separately. At closeout filing, this cross-border vehicle procurement guide can be used to review the records made before and after. A reviewer can walk the decision path again from the key collection record and confirm that no step was skipped.
