Abstract: A plunger storage unit with a base and a cap secured to the based. The base has a handle receiving void. A handle adapter is received in the handle receiving void. The handle adapter has an inner arc and an outer arc with a land between the inner arc and outer arc. Upper tabs and lower tabs are attached to the outer arc such that when the handle adapter is in the handle receiving void a portion of the cap is between the upper tabs and the lower tabs.

Abstract: An electronic lock box contains a secure compartment for storing keys to a structure. A linear actuator moves in one direction opening the door to the secure compartment, and moves in the opposite direction releasing a shackle that holds the lock box to the structure. A lock box system uses an encryption algorithm to diversify user PIN data at a central computer, and stores that diversified information on a memory card for later use when the user attempts to access a lock box. The central computer and electronic lock box both keep track of system “epoch time,” and the memory card must be presented to the electronic lock box within a correct epoch time window for the diversified PIN data to be successfully decrypted and compared to the user's PIN data that is entered on a keypad of the electronic lock box.
