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.

The Keymaker is an "Exile," a program whose usefulness has come to an end and that has chosen to hide in the Matrix rather than be deleted. The Oracle tells Neo that he will need the Keymaker's help in order to reach the Source, the machine mainframe; however, he is being held captive by a dangerous Exile known as the Merovingian. Neo, Morpheus, and Trinity are rebuffed when they demand that the Merovingian release the Keymaker, but his wife Persephone betrays him and takes them to where the Keymaker is being held: a small room in which he toils over a key-cutting machine. Thousands of previously made keys hang in bunches on the walls.

Morpheus and Trinity, separated from Neo, flee with the Keymaker as the Merovingian's Twins, the police, and three Agents (sent to terminate the Keymaker as he is an Exile) pursue them onto the city freeways. The Keymaker assists in the escape by quickly providing Trinity with the ignition key needed to start a motorcycle, saving her the time of having to have hot-wiring instructions uploaded into her mind.

Following the escape, the Keymaker meets with three crews of Zion rebels to describe the security measures in place around the building which houses the door that leads to the Source. Two electric power stations must both be shut down in order to disable the alarm system, after which Neo will have only a short time to reach the Source before the building is destroyed by explosives; in addition, if the door is opened while the alarm is still active, the explosives will detonate. As the other two crews attack the power stations, the Keymaker leads Neo and Morpheus to a hall within the building, filled with doors that represent backdoor access to other parts of the Matrix.
