Smart Lock ANSI/BHMA Security Grades
The ANSI/BHMA A156.40 security grade most smart-lock shoppers never check — sortable, with honest gaps where no manufacturer grade claim exists.
Electronic and smart door locks are usually marketed on app features, fingerprint sensors, and Matter/HomeKit badges — the ANSI/BHMA A156.40 (or A156.36) security grade rarely appears above the fold, and several popular models never state one at all. This table lists connectivity, unlock methods, deadbolt vs. retrofit design, HomeKit/Matter support, and manufacturer list price alongside the grade claim (or its absence) for 29 widely sold models, each with a `basis` noting exactly where the grade figure came from.
ANSI/BHMA Grade 1 Smart Locks Smart Locks With HomeKit or Matter Support Smart Locks With Fingerprint Unlock
| '1' = highest security, '3' = lowest; 'not stated' = no grade claim found; 'disputed' = sources conflict | Retrofit units mount over an existing deadbolt and don't replace the exterior cylinder | True if the model supports Apple HomeKit and/or Matter (natively or via hub/module) | Manufacturer-published list price where found; many manufacturers are MAP-restricted and don't post direct pricing (null = not published by maker) | True if the unit mounts over an existing deadbolt rather than replacing its exterior cylinder/strike | |||||
