Shopify Smart Lock & Access Control Schema — Z-Wave vs Zigbee vs Wi-Fi vs Thread, Backset Size (2‑3/8″ vs 2‑3/4″), ANSI Security Grade, Door Handedness, Hub Required vs Cloud-Only

Connectivity Protocol — Hub Required vs Cloud-Only vs Local Control

Smart lock connectivity determines what infrastructure the buyer must already own, how the lock behaves during internet outages, battery life, and which voice assistants and smart home platforms are natively supported. These are purchase-critical decisions for most smart home buyers.

Smart Lock Connectivity Protocol Comparison

Encode connectivity_protocol as a comma-separated list of supported protocols ('Z-Wave Plus', 'Zigbee', 'Wi-Fi 2.4GHz', 'Bluetooth 5.0', 'Thread'). Encode hub_required as a boolean (true for Z-Wave and Zigbee locks; false for Wi-Fi and Bluetooth locks that connect directly). Encode compatible_hubs as a comma-separated list of compatible hub brands for Z-Wave/Zigbee locks.

Backset Size — The Physical Fit Measurement That Cannot Be Adapted

Backset is the distance from the edge of the door to the center of the lock borehole (the hole in the door where the lock cylinder sits). It is the single most important compatibility measurement for replacing or installing door hardware. Getting the backset wrong means the purchased lock cannot be physically installed without modification to the door.

Standard Backset Dimensions

Backset cannot be adapted by shimming or simple modification — the lock mounting plate and bolt tailpiece are designed for a specific backset. A 2-3/8 inch lock on a 2-3/4 inch door will have the tailpiece too short to engage the latch; a 2-3/4 inch lock on a 2-3/8 inch door will protrude. Encode backset_size_in as '2-3/8', '2-3/4', or 'adjustable (2-3/8 and 2-3/4)'. Buyers who don't know their backset can measure with a tape measure in 60 seconds by measuring from the door's edge to the center of the current lock cylinder.

ANSI Security Grade — What the Standards Actually Test

ANSI/BHMA door lock grades are the US industry standard for security and durability testing. The grade rating appears in marketing but is often misunderstood — it is a minimum performance threshold, not a relative ranking from 1–3 where Grade 1 is "best" (though in practice, Grade 1 does represent higher security).

ANSI Grade Requirements Summary

Note: August Smart Lock Pro and similar retrofit locks inherit the ANSI grade of the existing deadbolt being automated — they do not have their own ANSI rating. For retrofit smart lock modules, encode ansi_grade as 'N/A (retrofit — grade of existing deadbolt)'. For integrated smart deadbolts (Schlage, Kwikset, Yale), encode the ANSI grade as an integer.

Access Methods and Battery Life

Smart locks offer multiple access methods that may or may not be available on every model. Buyers frequently purchase based on a specific access method (fingerprint, fob, voice) only to discover it is not supported on the model recommended.

Smart Lock Access Methods Reference

Encode access_methods as a comma-separated list of supported access methods. Encode user_codes_count as the maximum number of unique user PINs the lock stores (typically 30–500). Encode battery_life_months as the typical months at average usage with the specified battery type.
