A user places their individual USERfob in the slot next to the desired key allowing them to remove the KEYfob with the keys they want.

The USERfob remains locked until the KEYfob is returned. Each USERfob can be customized with a Name ID anit-tamper seal which identifies who is currently holding the key. Once the KEYfob has been returned, the USERfob is released allowing users to repeat the process with different keys they require.
