Group 1 VS Group 2 Locks

Group 1 locks are mechanically more complex than Group 2 devices. This increased complexity is employed to achieve resistance to expert lock manipulation, a threat not typically associated with residential safes. Group 1 locks are recommended for certain government security containers and for certain UL Listed Burglary Safes test under UL Standard for Safety 687. This does not include Residential Security Containers.
