Smart Lock Compatibility Checker 2026 — Which Smart Lock Fits Your Door?
Most smart lock buying mistakes come from skipping three compatibility checks: door type, deadbolt type, and backset measurement. A smart lock that is rated for thousands of five-star reviews will not fit a European multipoint door, a double-cylinder deadbolt, or a door with a mortise lock — and most product listings do not make this obvious.
The smart lock compatibility checker above filters by your exact setup. For standard US single-bore doors with a single-cylinder deadbolt, you have the widest selection of compatible locks. For everything else — sliding doors, French doors, European locks, or double-cylinder deadbolts — you will need a specific product category that the tool flags immediately.

What Is Backset Size and How Do I Measure It?
Backset is the distance from the center of your door’s bolt hole to the edge of the door. US doors come in two standard backset sizes: 2-3/8 inches (60mm), which is the most common size in modern homes built after 1990, and 2-3/4 inches (70mm), which is common in older homes and some commercial doors. To measure, open your door, find the center of the hole where the bolt slides in, and measure straight across to the door edge.
The good news: virtually all current smart locks — including the Schlage Encode Plus, Yale Assure Lock 2, and August Wi-Fi Smart Lock — include an adjustable latch that works with both 2-3/8 inch and 2-3/4 inch backsets. Backset is rarely a reason to reject a lock, but it is worth confirming before ordering.
Smart Lock Ecosystem Compatibility in 2026
Matter is the most important development in smart lock compatibility since Bluetooth. Since 2023, Matter-certified smart locks work natively with Amazon Alexa, Google Home, Apple HomeKit, and Samsung SmartThings — all from a single device with no separate bridges required. If you run Home Assistant, Matter locks are supported via the Matter integration from version 2022.12 onwards, and Z-Wave and Zigbee locks remain the most local-control-friendly options via the Z-Wave JS integration.
