No, Schlage and Kwikset locks do not use the exact same pin dimensions, keyway profiles, or internal tumbler specifications. Schlage locks typically utilize a standard C keyway with narrower, differently shaped pin chambers and specialized bottom pins. Kwikset locks utilize a standard KW1 keyway profile with wider cylinder plugs and distinct pin lengths. While a locksmith's universal pinning kit contains fractional master pins that can theoretically service both, their standard factory keys and tumbler dimensions are completely incompatible.
