A U-lock keyway protector comprising a cylindrical tube mounted for rotation on a U-lock crossbar. The keyway protector generates enough friction against the crossbar to allow only manual rotation, and it provides a secure grip for ease in rotation. A keyway aperture allows access to the U-lock keyway when in an unprotective position and denies access when in a protective position. When the U-lock is engaged, a shackle leg extends through a shackle slot, preventing longitudinal movement of the keyway protector along the crossbar. A lip at the edge of the keyway protector limits the distance that the keyway protector can be slipped onto the crossbar and eliminates alignment problems.
