Srwtrchry 5.0 Cubic home safes with interior safe lock box fire-resistant and water-resistant safe bag dual key system safety box with code wall-mount large safes floor safes hand gun safes please read this description carefully before purchasing the design concept of this double lock safe stems from the need to protect confidential documents or valuable assets. For example in an office setting where both a and b jointly secure a confidential document it’s crucial that only both of them can access it. To meet this need we have developed a dual-key locking system. The unlocking mechanism requires both the master key and emergency key to be used simultaneously and the keys can be distributed to two different individuals for safekeeping. This is a dual-key system safe meaning both keys must be used together to unlock the safe. However if you prefer not to use the dual-key function you can simply insert the left master key and rotate it to the horizontal position before removing it. Afterward you can unlock the safe using either the combination or the auxiliary key alone. This dual-key unlocking mechanism has a wide range of applications and can be used in offices banks homes hotels and other secure environments. Constructed from durable materials it offers a large capacity to store important valuables such as cash jewelry documents watches and firearms.
