Simple instructional video showing how to change the combination of the Master Lock ‘Select Access’ 5401 key storage unit.
Introducing the Master 5401 Key Storage Box. This simple-to-use unit is ideal for the storage of a small number of keys, and is operated via a 4- digit combination lock. The Master 5401 comes factory-set to 0000. To change the code, input your 0000 and open the unit up. To change the combination, push the Reset button across and up. Now select any 4-digit code of your choice. In this instance, we’re changing the code to 1001. Once your combination has been put in, return the Reset button to its original position. With the door open, check your code several times, to make sure that it’s correct before locking the unit.
