Schlage Encode vs Yale Assure Lock 2: Which Smart Deadbolt Wins

In Plain English

Quick Take

The short version: the Schlage Encode and Yale Assure Lock 2 are two WiFi-connected touch keypad deadbolts aimed at the same buyer, but the evidence clearly favors Schlage — a higher rating across a much deeper review base. Yale’s case rests on DoorSense’s door-position confirmation and ecosystem fit for buyers already running August or wanting Apple Home Keys, not on outright rating. The sections below walk through connectivity, keypad entry, install, battery, security and ecosystem in turn, so you can weigh the tradeoff on the dimensions that matter for your door.

Representative Products Compared

Connectivity and Remote Access

Schlage Encode has WiFi built directly into the lock, so it connects straight to your home network with no separate bridge accessory to buy or configure. That gets you remote lock and unlock from anywhere, plus activity notifications in the app, right out of the box. Yale Assure Lock 2's connectivity depends on the specific variant — the "with Wi-Fi" versions include built-in WiFi, while Bluetooth versions rely on a separate Yale Wi-Fi bridge accessory for full remote access. Check the current listing carefully before ordering if remote access without an extra accessory is a requirement, not just a nice-to-have.

Keypad and Entry Method

Both locks use a touch keypad as the primary entry method, and both include a backlit keypad for use at night. Schlage Encode pairs the keypad with app-based unlock and auto-lock. Yale Assure Lock 2 does the same, and adds DoorSense, which confirms the door is physically closed before triggering auto-lock rather than relying on a simple timer. The Schlage Encode has no fingerprint reader, while Yale sells a fingerprint version (the Assure Lock 2 Touch) alongside plain keypad models — check which Yale variant a listing is for, or see leading fingerprint locks for dedicated picks.

Installation and Door Compatibility

Both locks are designed as direct retrofits for a standard US deadbolt hole. Most owners install either one in under an hour with a Phillips screwdriver and no locksmith. Measure your door's backset and thickness against each lock's listed compatibility range before ordering — a mismatch is the most common return reason in this category, on either brand. See our full smart deadbolt retrofit walkthrough for the general retrofit process both locks follow.

Battery Life

Both locks run on standard batteries with a low-battery warning through the keypad before they die. WiFi connectivity and app notifications draw more power than a purely offline lock on either model, and some owners report shorter battery life in cold weather regardless of brand. A physical key is the fallback on a dead battery: the Schlage Encode has a standard 5-pin keyed cylinder (one key included), and Yale's keyed versions include a key override — but Yale also sells key-free Assure Lock 2 versions with no cylinder, so check which one you're buying.

Security and Build Quality

Schlage lists the Encode as certified to ANSI/BHMA A156.40 Grade AAA (plus A156.36 Grade 1), and Yale lists the Assure Lock 2 as ANSI/BHMA Grade 2. That certification is a more meaningful security measure than either lock's connectivity. Schlage brings decades of manufacturing experience specifically in physical lock hardware, which shows up in owner reviews as confidence in the underlying deadbolt mechanism. Yale carries a similarly long history in residential locks, reinforced by its affiliation with August on the smart-home side.

Ecosystem and App

Schlage Encode integrates with its own app for code management, activity logs and remote access, and works with Amazon Alexa and Google Assistant; Apple Home Key support is reserved for the separate Schlage Encode Plus. Yale Assure Lock 2 works through the Yale app and, per Yale, with Amazon Alexa, Google and Siri, with Apple Home Key support on the Assure Lock 2 Plus for buyers already invested in that ecosystem. If you're already running August devices, that tie-in is a real reason to lean Yale despite the lower rating.

Price Tier and Value

Schlage Encode and Yale Assure Lock 2 are roughly comparable on price, with Yale sometimes pricing slightly higher depending on the specific variant and finish chosen. Check the current listing for both, since prices shift by finish and bundle, but neither lock sits meaningfully outside the other's range at the WiFi-connected deadbolt tier. A Yale bundle that includes the Wi-Fi Bridge will typically cost more than one that doesn't, so compare like for like before assuming a straight price gap between brands.

Use Cases

Schlage Encode suits a primary front door where you want the deepest review base and a straightforward, standalone app experience with no other ecosystem dependency to manage. Yale Assure Lock 2 suits a household already running August devices, wanting Apple Home Keys on a compatible variant, or specifically valuing DoorSense's confirmed-closed auto-lock behavior over a timer-based one. Both are legitimate picks for a rental or short-term let, with the choice mostly coming down to ecosystem fit rather than raw capability, so it's worth being honest about which one actually describes your household before you buy.

Who Should Buy Which

Choose Schlage Encode if you want the strongest all-round evidence, the deepest review base of any smart deadbolt on this site, and a standalone app experience without needing an existing ecosystem investment. Choose Yale Assure Lock 2 if DoorSense's door-confirmed auto-lock matters to you specifically, or you're already running August or want Apple Home Keys support on a compatible variant — that ecosystem fit is a legitimate reason to choose Yale despite the lower overall rating. Neither lock is a bad purchase; the honest gap between them is narrower than a quick glance at the star ratings alone would suggest.

Winner by Use Case

Best all-round rated smart deadbolt: Schlage Encode, on both average rating and review depth, by a clear margin.

Best for confirmed-closed auto-lock behavior: Yale Assure Lock 2, on the strength of DoorSense.

Best for August or Apple Home Key ecosystem fit: Yale Assure Lock 2, specifically on select compatible variants.

Best default with no existing ecosystem investment: Schlage Encode, since it needs nothing else to work well.

Going Deeper: How DoorSense Knows the Door Is Shut

DoorSense is a magnetic door-position sensor rather than a camera or a timer. Yale’s DoorSense troubleshooting page explains that the system uses magnetic fields to determine whether the door is open or closed: a magnet is fitted on the door frame, and the lock senses its field. When the door swings open, the magnet moves away, the field around the lock changes, and the lock can report the door’s position in the app.

That is what makes the auto-lock behaviour different. Yale says that with DoorSense you can set up auto-lock in the Yale Access app so the door locks behind you when you walk out, meaning the lock waits for a closed door rather than simply counting down. A pure timer, like the Schlage Encode’s time-delayed auto-lock, cannot tell whether the door is shut; it only knows how long ago it was unlocked. That is why reviewers treat DoorSense as the more trustworthy behaviour on a door that does not always close fully on its own.

Magnetic sensing has practical limits, and Yale’s own guidance reflects them. Yale says setup includes in-app calibration steps, that a spacer can be fitted behind the magnet to bring it level with the door, that a second magnet can be stacked on the first to strengthen a weak field, and that any change to the magnetic field around the lock, such as removing and replacing the battery cover or bringing another magnet into range, can affect accuracy. In practice, DoorSense rewards a careful install: calibrate it, test it with the door ajar and fully closed, and recalibrate if the app’s status ever disagrees with the real door.

Verdict

Choose the Schlage Encode for the strongest all-round evidence and rating. Choose the Yale Assure Lock 2 specifically if DoorSense’s door-confirmed auto-lock or Yale/August/Apple Home ecosystem fit matters more to you than the rating gap.
