Keyloid

The Keyloid appeared in 2012 TV series called Tokumei Sentai Go-Busters. The Keyloid (キーロイド, Kīroido) is a Metaloid that Escape created when she used the "close" Metavirus to infect a keychain to imprison people in a building for the KeyZord to destroy.

By hitting something with a beam emitted from his forehead, the Keyloid then uses it's key that consists of his right arm to make things inoperable, from making a building's doors refusing to open to jamming an Ichigan Buster.

However, it's greatest tool is also it's greatest weakness, as shattering the key will undo all progress the Keyloid has done.

After the Busters freed the people from a squad of Buglars that tried to keep everyone inside the building so the Keyloid could lock down the building again, this Metaloid was destroyed by both the Beetle Busters' Morphin Blaster and Blue Buster's Ichigan Buster in Special Buster Mode.
