Level Lock+ (Matter) Smart Deadbolt
The world's smallest smart lock — all technology is hidden inside the deadbolt. Matter-over-Thread connectivity, Apple Home Key with tap-to-unlock, and ANSI Grade 1 security.
Pros
- ANSI/BHMA Grade 1 security certification—the highest residential rating, providing superior drilling, picking, and forced entry resistance compared to most smart locks
- Completely invisible smart technology with all electronics hidden inside the deadbolt, maintaining your home's aesthetic without external smart lock appearance
- Apple Home Key support allows iPhone and Apple Watch users to unlock with a simple tap via NFC, no app opening or Face ID required
- Matter-over-Thread connectivity ensures compatibility across major platforms (Apple Home, Google, Alexa, SmartThings) with future-proof interoperability
- Simple 15-minute installation that replaces standard deadbolts without requiring additional drilling or complicated wiring
- One-year battery life from a single CR2 lithium battery reduces maintenance frequency compared to many smart locks requiring more frequent changes
Cons
- $329 price point is significantly higher than most smart locks ($150-250 range), making it a premium investment for aesthetic and security features
- Only two finish options (Satin Nickel and Matte Black) limit design flexibility compared to competitors offering bronze, brass, and other finishes
- No built-in keypad option for code entry—relies entirely on smartphone, physical key, or auto-unlock, which may inconvenience guests or non-smartphone users
- Thread/Matter ecosystem still maturing with occasional connectivity quirks reported in reviews, requiring a compatible Thread border router for full functionality
Overview
The Level Lock+ (Matter) is the smart lock for people who hate the way smart locks look. While every other smart lock bolts a bulky electronic housing onto your door, Level has engineered all of the technology — motor, batteries, sensors, and radio — inside the deadbolt itself. From the outside, your door looks exactly like it has a normal lock. It's an extraordinary feat of miniaturization.
But the Level Lock+ isn't just a design statement — it's genuinely one of the most capable smart locks available. Matter-over-Thread connectivity means it communicates directly with your smart home hub (Apple Home, Google Home, Amazon Alexa, or Samsung SmartThings) without WiFi, delivering faster response times, better battery life, and more reliable operation than WiFi-based locks.
Apple Home Key is the headline feature for iPhone users. Simply tap your iPhone or Apple Watch to the lock, and it unlocks — no app required, no fumbling with your phone. It works even when your phone's battery is dead (for up to 5 hours). It's the closest thing to the effortlessness of a traditional key, but smarter.
For non-Apple users, the Level app provides keyless entry via phone proximity, shareable digital keys with schedules and expiration dates, and a complete access log. You can set up auto-lock timers and get notifications when the door is locked or unlocked.
Security is taken seriously. The Level Lock+ carries an ANSI/BHMA Grade 1 rating — the highest residential security grade, meaning it meets commercial-level standards for strength and durability. The CR2 battery lasts approximately one year with typical use, and the lock gives you advance warning when it's time to replace.
Installation takes about 15 minutes if you're replacing a standard single-cylinder deadbolt (which most homes have). The only caveat is compatibility — Level works with most standard deadbolt preparations, but you should check their compatibility tool before purchasing.
The Level Lock+ proves that smart home technology doesn't have to be ugly. It's secure, reliable, invisible, and a joy to use.

Who Is It For?
The Level Lock+ is ideal for design-conscious homeowners who refuse to compromise aesthetics for smart home functionality, particularly those deeply invested in the Apple ecosystem who value Home Key's tap-to-unlock convenience. It's also perfect for security-focused buyers who want Grade 1 certification and Matter's future-proof interoperability. However, budget shoppers, those wanting keypad access for guests, or buyers needing more finish variety should consider alternatives.
Full Review
The Level Lock+ (Matter) represents a sophisticated approach to smart locks, prioritizing aesthetics and modern connectivity standards over flashy features. Its claim to fame is truly invisible smart technology—all electronics are housed within the deadbolt itself, leaving the exterior and interior looking identical to a traditional lock. This ANSI/BHMA Grade 1 certified deadbolt delivers the highest residential security rating while supporting Matter-over-Thread connectivity, ensuring compatibility with Apple Home, Google Home, Alexa, and SmartThings ecosystems. The Apple Home Key integration is particularly impressive, allowing iPhone and Apple Watch users to unlock with a simple tap via NFC—no app opening required. Installation takes roughly 15 minutes and replaces your existing standard deadbolt, with a CR2 lithium battery providing approximately one year of operation.
At $329, this is a premium-priced lock competing in a market where capable smart locks often cost $150-250. What you're paying for is the invisible design, Grade 1 security certification, and future-proof Matter support—features that matter significantly to certain buyers. The 4.4-star rating across 342 Amazon reviews suggests generally satisfied customers, though the price point and limited finish options (only Satin Nickel and Matte Black) may give some pause. Compared to other smart home products in its price range like the Philips Hue Starter Kit ($241.99) or Google Nest Learning Thermostat ($191.88), the Level Lock+ commands a premium but delivers something unique: security hardware that doesn't compromise your home's aesthetic. For those valuing design discretion, Apple ecosystem integration, and Matter's interoperability promise, this lock justifies its cost. However, budget-conscious buyers or those wanting built-in keypads should explore alternatives. Our recommendations may include affiliate links, which help support our honest, independent reviews.
