The PAC-KEEPER-SFIC is a physical key management system that virtually guarantees that the key will get returned - something that other non-electrified key control devices cannot. Made in the USA from 6061 aircraft-grade aluminum, the innovative ball bearing locking PAC-KEEPER-SFIC will protect your most important keys by insuring that the key is either returned or that you have proof of who removed it. With the PAC-KEEPER-SFIC, the "Controlled Key" is locked into the device and can only be removed if a user has an approved "User Key." The PAC-KEEPER-SFIC works with your small format IC cores from Medeco, Falcon, Best, Arrow, and others.
