If I recall, to be a true Grade 1 one needs to pass a UL test for your electronics to withstand a minute of fire which requires packing them in sand. We're fine being labeled a Grade 2 if we're using a Grade 1 deadbolt, Grade 1 keyway, and Grade 2 electronics.
Some locksmiths are trying to revoke the Grade 1 rating on those Kwiksets you mentioned because of the Smartkey vulnerability. (Grade 1 requires a certain threshold of "pick proof" and "drill proof" which they argue fails to hold up.) Bolt does not have that same vuln. but you can see what it looks like here: https://www.youtube.com/watch?v=H1mmjVvMsGs
That is incorrect. The ANSI grading applies to the mechanical lock, keyway, and cylinder only and that was my question. It has nothing to do with UL testing of the electronics or withstanding fire!
It has to do with how easily one can drill into it, or pry it off with a crowbar, or pick it etc.
The spec is only a few dollars, you might want to buy it from BHMA.
The point is Grade 1 ANSI rating is important and offers security against intrusion. You're offering everyone a Grade 2 bolt and from your response seem to be even confused about the difference between the two.
Your deadbolt as you already said is Grade 2. So now you're saying is Grade 1??!
