Keymaker
The Keymaker is a fictional character, portrayed by Korean-American actor Randall Duk Kim, in the 2003 film The Matrix Reloaded. He is a computer program that can create shortcut commands, physically represented as keys, which can be used by other programs to gain quick access to various areas within the simulated reality of the Matrix. He appears as an elderly, bespectacled Asian man dressed in a button-down shirt, smock, and an apron hung with bunches of keys.
