The Matchstick Key is one of the many Keys.
In 1915, the key was kept inside the Vault of Shadows by Chamberlin Locke. Through a crafty scheme by Chamberlin's son, John Locke, John procured the key among many other keys as weapons to turn the tide of World War I. Shortly after enlisting into the Allied in Belgium, John ambushed a German camp, where he used the key to incinerate Willem Veidt.
On June 4, 2016, a fire broke out in Burgess's old home at 12:03AM. According to reports, some teenagers teens found a key in Ravenscroft and used it to unlock a door on the property, but instead created a fire that left a Matchstick Key-shaped silhouette emblazoned on the remains, implying the key they used was the Matchstick Key. The key's current location after the fire is unknown.
The history of the key is unknown, however at some point in time, it became the property of Mark Cho. Cho would then hold the key for an undisclosed amount of time in a safe behind a framed photograph in his house.
When Mark learns of Rendell Locke's death, he gathers all documents pertaining to Keyhouse Manor, and stabs himself with the key. This causes him to combust into flames, burning his entire house — and the documents — to the ground.
An unknown amount of time later, the key falls into the possession of a teenage boy. It is eventually stolen from around his neck by Dodge, who proceeds to murder the boy via subway train. She uses it against the Locke family, and holds Bode Locke hostage in a circle of flames, to try to intimidate him to hand over the Head Key. Failing to retrieve the key, and revealing she can't steal it from Bode, she changes her strategy and gives the key to Sam Lesser, who uses it to escape prison.
While revealing the history of the Keepers of the Keys to Tyler and Kinsey, Ellie Whedon explains that when the Keepers split the keys, the Matchstick Key was given to Mark who was the only one who knew where all of the other keys were hidden at the Keyhouse. As a result, when Mark learned that Dodge was back and after the keys, he used it to commit suicide.
Following Sam's death at the hands of the Ghost Key, the key falls into the possession of Bode Locke who finds it in the yard days later. Bode later attaches the key to one end of a lightsaber and uses it to attack Dodge's shadow; this causes the shadow to explode.
While searching Eden Hawkins' head for answers, Kinsey comes under attack by mannequins and uses the Matchstick Key to destroy one of them. When one grabs on to Scot as they are climbing out, Kinsey tosses him the Matchstick Key and he uses it to destroy his attacker.
The key can be used to create fires when inserted into a door or touched to an object. Furthermore, any living thing stabbed with the key will combust.
- The Matchstick Key does not initially appear in the graphic novels; it was created specifically for the Netflix adaptation.
- The Matchstick Key appears to possess powers that are similar but not exact to the Splody Key, a key that only appears as part of Bode's Guide to the Known Keys journal. The difference being that the Matchstick Key causes fires, while the Splody Key causes explosions.
