Tips & Tricks

What's the real-world difference between an ANSI Grade 1 and Grade 2 lock — is it significant enough to matter for our front door?

Grade 1 locks are tested to 250,000 open-close cycles and higher strike impact thresholds compared to Grade 2's 150,000 cycles and lower resistance ratings — on a heavily used exterior door in Tempe's climate, that gap in durability becomes tangible over time. For a primary entry point, the upgrade to Grade 1 is one worth making. Sundial Locksmith installs both grades and can walk you through the right choice for each door — call (480) 525-7778 to get started.
