APCO Project 25 Over-the-Air-Rekeying Secure System When using a Key Management Facility (KMF) to perform Over the Air Rekeying (OTAR) on a unit, there can be numerous reasons for failure. If a, rekey message does fail, it is up to the user to attempt to determine what state the radio is in and then manually select an additional OTAR message or messages to make the unit current in the Kh4F's database. The user may not select the most secure or efficient OTAR messages to make the unit current.
