Security has always been a Knox strong point. Designed for maximum protection, each virtually indestructible box features a special high-security Medeco lock and key. This Medeco restricted locking system guards against unauthorized key duplication. Keys aren't even available to locksmiths or lock distributors, only The Knox Company can supply these keys!
The Knox Box system offers maximum security at every step. The department has an exclusive key code. All Knox Box stations in that city are keyed alike--and only the fire department has master keys.
