The Timeshift Key allows the user to witness past events as chosen through the grandfather clock in Keyhouse. Though they cannot interfere with the past, it can be used to gain information.

The date can be selected using the clock itself, and the earliest date available is January 13, 1775, the date Benjamin and Miranda Locke first encountered the Black Door.[1] The latest date available is December 31, 1999.

While time-travelling, the user can also leave the premises of Keyhouse.[2] In the present, they appear "white" to witnesses, though this may be just to people who can see the magic.

Time in the present passes much slower than the time spent witnessing the past. When Tyler and Kinsey spent two days in the past, they only "went all white for a second" in the present.[3]


The Timeshift Key was created between 1912 and 1914, by Harland Locke. Its original purpose was to allow Chamberlin Locke a way to revisit the history of his son, Ian. Chamberlin considered his use of the Timeshift Key to be a more responsible method to see his son, rather than the alternative, the Echo Key.[4]

The Timeshift Key was used by the Tamers of the Tempest circa 1988 to gain information about the Black Door.[2]

By the time the Locke children moved to Keyhouse, the Timeshift Key remained on top of the clock. When Tyler, influenced by Kinsey's fears and tears, attempted to destroy Keyhouse, he knocked over the clock and discovered the key.[5]

Tyler and Kinsey Locke first used the key to visit the earliest date they could, January 13, 1775. There, they learned the history of the Whispering Iron, Benjamin Locke, and the Black Door.[1]

They then used the Timeshift Key to witness the events surrounding the Tamers of the Tempest in 1988, and the history of Dodge.[3]
