A locking accessory for preventing unauthorized access to a high grade keyboard musical instrument is disclosed. The locking accessory includes a stationary shoe element permanently secured to the bottom surface of the instrument keybed and a generally C-shaped element adapted to be removably affixed and locked to the stationary element. The C-shaped element includes generally horizontal upper and lower sections connected by a generally vertical intermediate section. The lower section is adapted to slidably engage the stationary element such that the upper section, supported by the intermediate section, extends over and just above the closed fallboard, thereby preventing it from being opened. The lower section includes a lock and bolt assembly which, when actuated, moves a bolt into engagement with a corresponding bolt receiving aperture in the stationary element to permit securely locking the stationary and C-shaped elements together. A resilient coating on the inner surfaces of the C-shaped element serve to protect the fallboard finish from being marred.
