A vehicle lock assembly key hole cover having a flat or ovoid surface with an annular shoulder extending axially from the surface. The annular shoulder is formed with one of several features including a taper in cross-section, geometrically-shaped slots and elastomeric inserts to impart flexibility to the shoulder. An elastomeric sealing ring may be secured to an inner surface of the shoulder to create a seal and increase adhesion to a lock assembly. An adhesive patch may be used to enhance adhesion to a lock assembly.
