Schlage is one of the most well known and oldest brands of door locks available. With a lifetime mechanical warranty and their offering of popular styles, it is hard to go wrong with a Schlage lock. There are other brands that offer solid brass construction and custom designs that are not available with Schlage, but you won't necessarily get better performance from those brands. Schlage residential locks are made of zinc die-cast, similar to comparable brands like Kwikset, Sure-Loc, Weiser, Weslock, and more. In that segment, Schlage is on the higher end of quality and dependability.
