The Hyper Tough Keyed Entry Single Cylinder Deadbolt is a basic exterior door lock: key on the outside, thumb turn on the inside. It is ANSI Grade 3 rated, the entry-level residential security grade, so it suits a back or side door rather than a front entry you want hardened. The adjustable latch and reversible build fit standard doors, and installation needs only a screwdriver. Against Grade 1 and Grade 2 deadbolts it gives up pick and bump resistance and strike strength, but it covers the basics at a low cost. Owners rate it well overall, with most complaints about fit on non-standard doors and finish wear.
