Introducing the Master 5403 extra-large key storage device. This simple-to-operate unit is ideal for the storage of larger bunches of keys and access control cards. All the 5403s come factory-set to 0000. To change the code, enter 0000 and open the unit up. To change the combination, push the Reset button across and up. With the door open, select a 4-digit code of your choice. In this instance, we’re using 2001. With your new combination entered, return the Reset button to its original position. With the door open, check your code several times to make sure that it is correct before locking this unit.
