The difference between Kwikset 1 and 5 refers to the security grade of the lock, based on the ANSI/BHMA grading system. Grade 1 is the highest, offering maximum security and durability, while Grade 5 is not a standard ANSI grade and may refer to a lower security level or a marketing term. Typically, Kwikset Grade 1 locks are used for commercial or high-security residential needs, whereas lower grades are for basic residential use.
