In the "Locke and Key" season 2 trailer, something is afoot for the Locke siblings. The three kids learnt about the presence of magic keys in their father's family house in the first season of the hit Netflix show. With this strong magic at their fingertips, they'll begin to properly comprehend what they're in for, according to the season 2 teaser.

After Tyler, Kinsey, and Bode Locke discovered the magical keys strewn about their father's house in season one, they spent the majority of their time attempting to safeguard the objects from a demon named Dodge who wanted to capture them for herself. While the Lockes assume they have won in the season 1 finale, the last minutes reveal that Dodge has deceived them and obtained one of the keys.

She's enlisted the services of another individual to bring the Lockes down, which spells danger for the family. The core storyline of the second season appears to be this, as the monster is kept at bay as the Lockes discover more about the keys, according to the season 2 trailer.
