Cold In Death
A multi-purpose key used by law-enforcement
Uses: internal battery lasts about 1 year
Description: The Masterkey is a small credit-card sized piece of plastic used by law-enforcement officials to open virtually any commercial or standard lock. With card-locks, the key can just be swiped in the slot and over-rides the program. In key locks, a key pops out and conforms itself to the tumblers inside the lock, allowing it to be opened.
-Some locks are immune to a Master and must be forced open in other ways.
