Eliminate the risk of forgotten combinations. The Kensington ComboSaver Master Coded Combination Notebook Lock provides both combination and master key access when used in conjunction with a ComboGenie (sold separately, sku K67711US). The ComboGenie serves as an electronic "opener" and creates a proprietary authentication process for secure combination recovery ideal for situations where a large number of combination locks need to be administered by a person who is the authorized master key administrator.
