Keymaker

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.

The Keymaker assists in the escape by quickly providing Trinity with the ignition key needed to start a motorcycle, saving her the time of waiting for hot-wiring instructions to be 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.

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.

Before dying, he gives Neo a single key on a chain around his neck—the one needed to reach the Source—and points Morpheus toward a door that will allow him to re-enter the Matrix proper.

[2] He is a creation of collaboration;[3] for example, Lana Wachowski suggested that Kim cut his stride in half, so that the Keymaker's movements appeared as more of a scurry, than a normal gait.
