Best Smart Locks That Work With Apple HomeKit (2025)

A HomeKit-compatible smart lock should offer: native HomeKit support (not via a bridge), reliable locking and unlocking via the Home app or Siri, auto-lock functionality, and optionally, an access code keypad for guests who don't have iPhones. Battery life is also critical — most smart locks run on AA or CR2 batteries and last 6–12 months under normal use.

Thread support (available on newer Matter-certified locks like the Yale Assure Lock 2) is a bonus, providing faster response times and a more reliable connection compared to Bluetooth-only locks. If you have an Apple TV 4K or HomePod as a hub, Thread-enabled locks will be noticeably more responsive.

The Yale Assure Lock 2 is the top recommendation for most HomeKit users in 2025. It supports HomeKit natively (via the Yale Access app), includes a backlit keypad for access codes, supports Thread (making it one of the first Matter/Thread deadbolts), and replaces only the interior side of your deadbolt — meaning the exterior looks like a standard lock to visitors and potential burglars.

Setup takes about 15 minutes if you're familiar with deadbolt installation. The Yale Home app handles pairing to HomeKit, and once added, you can control it via Siri, set auto-lock timers, and create automations like 'Lock the front door when I leave home'. Battery life is approximately 6 months with normal use. Available in satin nickel, oil-rubbed bronze, and matte black.

The August Smart Lock Pro is the best choice for renters or anyone who doesn't want to replace their existing deadbolt. It mounts on the interior side of your existing deadbolt, leaving the exterior completely unchanged — your existing keys still work, and you keep your current lock hardware. Setup takes about 5 minutes.

The August Pro supports HomeKit via the August Connect Wi-Fi bridge (included) and offers auto-lock, auto-unlock based on geofencing, and guest access via the August app. The main trade-off compared to Yale is that it requires the Connect bridge plugged into a nearby outlet for remote access — without it, you're Bluetooth-only.

The Schlage Encode Plus is a premium deadbolt with built-in Wi-Fi, a backlit keypad, and native HomeKit support without any hub or bridge required. Unlike the August (which uses a separate bridge) or the Yale (which uses a hub for Thread), the Schlage Encode Plus connects directly to your Wi-Fi router and appears in HomeKit as a first-class accessory.

Schlage locks are known for their commercial-grade build quality and ANSI/BHMA Grade 1 certification, making them one of the toughest options available. Battery life is around 6 months. The downside is price — the Schlage Encode Plus is typically $30–$50 more expensive than the Yale Assure Lock 2 — but for the keypad and direct Wi-Fi HomeKit support without any bridge, many users find it worth it.

The Level Lock Plus is the most discreet smart lock available for HomeKit. The electronics are built entirely inside the deadbolt cylinder itself, so from the outside — and even from the inside — it looks exactly like a standard deadbolt. There is no keypad and no motor housing visible. It pairs directly to HomeKit via Bluetooth.

The Level Lock Plus supports HomeKit natively and requires the Level app for initial setup. It has a very small physical footprint and works with existing door hardware. The main limitation is no keypad for guest codes — guests need the Level app to unlock, or you leave them a physical key. For privacy-conscious homeowners who want smart lock functionality without advertising it, Level Lock Plus is unmatched.

All HomeKit locks support remote access when you have an Apple TV (4th gen or later), HomePod mini, or HomePod (2nd gen) set up as a home hub. Without a hub, HomeKit locks work only when your iPhone is in Bluetooth range of the lock. For automations like 'lock when I leave home' to work reliably, a home hub is essential.

If you don't have an Apple TV or HomePod, the HomePod mini is the most affordable option at around $99 and handles all home hub duties including remote access, automations, and notifications for lock state changes.
