Abstract
A lock key comprising of (3) pieces. A head, a key blade and a snap lock. These pieces are interlocked together, so that separation is not possible in normal usage. The head is made of precious metal or non precious metal set with or without stones and may consist of various esthetic and ornamental forms. The snap lock engages the head and the key blade in a way to inhibit the removal of the head from the key blade in normal use. The key blade can be easily removed from the head and exchanged with another key blade as needed.
