Hexagonal key is a still life with 13 cells, and the smallest that stabilizes a pre-block as its own island differently from the aircraft carrier.

Hexagonal key reaction

Like the aircraft carrier, the insular pre-block can be turned into a lightweight spaceship by colliding a single glider into it in the pre-pre-block reaction. The remainder of the still life, after perturbation by the escaping LWSS's tail sparks, will evolve into a blinker.

By placing two blocks next to the still life, the leftover debris is turned into two gliders:
