How to choose an Apple Home smart lock
First, separate two things that sound alike: HomeKit support and Home Key. HomeKit support means the lock appears in Apple’s Home app and answers to Siri — all three picks here do that. Home Key is the extra: an NFC feature that lets you hold your iPhone or Apple Watch to the lock to unlock, no app needed. The Schlage Encode Plus and the Level Lock+ both offer Home Key; the August works with Apple Home but relies on the app and auto-unlock rather than a tap.
Retrofit, hidden, or full replacement?
These three represent the three lock philosophies, which is handy. The August is a retrofit— it clamps onto the inside of your existing deadbolt, so you keep your keys and your exterior hardware, which makes it the renter-friendly choice. The Level Lock+ hides all its electronics inside the deadbolt so the door looks completely untouched. The Schlage Encode Plus is a full replacementwith a keypad on the outside — the most capable, and the most solid-feeling. Match the philosophy to whether you can change the exterior hardware and whether you want a keypad.
Connectivity and how it fails safe
The way a lock connects affects both convenience and battery life. Thread and Bluetooth are efficient; always-on Wi-Fi is convenient but drains batteries faster. Whatever the radio, a good smart lock still has a mechanical fallback— a physical key or a keypad code — so a dead battery or a downed network never leaves you on the doorstep. We dig into exactly what keeps working when the Wi-Fi or the power drops in our guide to smart locks without Wi-Fi.
How you’ll actually get in each day
The nicest thing about an Apple Home lock is how varied and forgiving everyday entry becomes, so it’s worth picturing your real routine. With Home Key(Schlage and Level), you hold your iPhone or Apple Watch near the lock and it opens — no app to launch, no code to type, and it works even if your phone’s battery is low, thanks to the phone’s power reserve. The August leans instead on auto-unlock: it senses you arriving and unlocks the door as you walk up, hands-free. All three also give you the ordinary fallbacks — a keypad code on the Schlage for guests or kids without a phone, and your existing physical keyon the August and Level, since they keep your original cylinder. In practice most households mix these: Home Key or auto-unlock for the adults, a code or a key for everyone else. Think about who needs to get in and how, because that — more than any spec — decides which of the three fits your door.
What about a mixed or Android household?
Apple Home locks aren’t Apple-only in every respect, but the experience is best on Apple devices. The Schlage and August also work with Alexa and Google, so they suit a mixed householdwhere some people are on Android — everyone still gets app and voice control, and only the Apple users get Home Key or the deepest Home app integration. The Level leans hardest into Apple, so it’s the least flexible of the three for a non-Apple home. If your household is entirely on Android, you’re usually better served by the wider best smart lockslist, where Home Key isn’t a factor and the value is often better.
Security and setup
A smart lock is only as safe as the account behind it, so use a strong, unique password and turn on two-factor authentication — the same basics we’d urge for any connected device. And whichever you choose, confirm it fits your door (backset, bore and door thickness) before you buy, since a lock that doesn’t fit is the most common return. If Apple Home isn’t a hard requirement, the keypad and fingerprint locksopen up cheaper options; if you’re cross-shopping the big names, our Yale vs Schlage comparison covers the build-quality question in depth.
