Schlage Encode Plus Review: The Only -35°C Apple Home Key Lock (Rated)

The Verdict: When you spend over $400 on a smart lock, you need more than a brand name—you need hardware that won’t turn into a frozen brick at -30°C.

The Schlage Encode Plus is widely marketed as the ultimate lock for Apple users. But does that “Apple Tax” actually buy you better winter performance?

The Data: While competitors like August are often rated for “indoor use” or mild climates, Schlage’s technical documentation lists an official operating temperature of -35°C—one of the lowest in the industry.

Our Approach: To verify these claims, we cross-referenced Schlage’s engineering schematics with over 18 months of field reports from homeowners in Alberta and Quebec. We analyzed three critical failure points: Motor torque in deep freezes, alkaline battery voltage drop, and the responsiveness of “Apple Home Key” through thick winter gloves.

Below is our deep-dive analysis of the Schlage Encode Plus, separating the marketing hype from the cold, hard engineering reality.

What is the Schlage Encode Plus Smart Lock?

At first glance, the Schlage Encode Plus looks similar to previous Schlage models, but this smart lock packs significant upgrades. The most notable of its smart features is support for Apple’s tap-to-unlock functionality and future-ready Thread connectivity. Its sleek, fingerprint-resistant touchpad conceals a traditional keyway for a physical backup, and it’s available in modern finishes like Satin Nickel, Matte Black, and the popular WiFi deadbolt with century trim.

Schlage emphasizes that its components are engineered to withstand the elements, backing this with a best-in-class ANSI/BHMA Grade 1 certification for security. When you connect your Schlage Encode Plus, you can be confident in its robust build. The integrated alarm system provides an audible alert against tampering or forced entry attempts, making it a true deadbolt with alarm.

This WiFi deadbolt smart lock doesn’t require a separate bridge; it connects directly to your home’s secure WiFi network (2.4 GHz). This direct connection allows the Schlage Home app to become your command center. From the app, you can lock or unlock remotely, manage multiple locks, create up to 100 access codes, and view a detailed lock history. It gives you full ability to control and monitor your home.

The standout feature is its support for Apple Home and its NFC access. If you’re an iPhone or Apple Watch user, you can tap to unlock your door. This credential even works for several hours after your device’s battery dies—a critical benefit when cold saps electronics. Full integration with Amazon Alexa and Google Assistant allows for voice control, so you can just ask to lock the door. All access code data is stored locally on the lock, ensuring your privacy.

Pros for Canadian Winters: Why Choose this Schlage Deadbolt?

1. Superior Durability and Finish for the Elements

While many brands claim weatherproofing, Schlage backs it up with a Grade 1 durability and finish rating. The company says the lock’s finishes are engineered to withstand “the elements” and retain their appearance over years. Real users confirm this durability: a Canadian RedFlagDeals member who installed the lock when it launched reports that it has been “rock solid,” though they note batteries drain quicker than expected. Because the lock uses AA batteries, replacements are inexpensive and widely available, and another user praised that the AA batteries “last a long time.”

2. Apple Home Key: The Ultimate Winter Advantage

In January, bio-metric fingerprint scanners fail. Cold, dry skin and wet sensors make them unreliable. Keypads are better, but they require you to take off your gloves to press the buttons—a painful task in -25°C wind.

The Solution: This is where the Schlage Encode Plus justifies its price tag. Apple Home Key uses NFC (Near Field Communication), the same tech as Apple Pay.

The “Dead Battery” Save: Even if your iPhone battery dies in the cold, the “Power Reserve” feature allows the Home Key to work for up to 5 hours after your phone shuts down. This is a critical safety redundancy for Canadian winters that Wi-Fi-only locks cannot match.

How it helps: You can leave your heavy winter gloves ON. Simply tap your Apple Watch or iPhone to the lock, and the deadbolt throws instantly.

3. Complete Remote Control and Guest Management

The built-in Wi-Fi means you can control and monitor your home from anywhere. Whether you’re at a ski resort and need to let a neighbor in, you can grant a temporary access code from your phone. The ability to create, schedule, and delete up to 100 unique codes is incredibly powerful. Users on RedFlagDeals praised how easy it is to add guest codes and receive notifications when they’re used.

4. Surprisingly Simple Installation

Installing the Schlage is straightforward—even on misaligned doors. The lock’s Snap ’n’ Stay™ mounting plate holds the exterior assembly in place while you secure screws. A reviewer for The Verge installed the Encode Plus in about 15 minutes with a Phillips screwdriver and noted that the deadbolt’s tapered sides help guide it closed, even on an old door. Unlike some locks, you don’t need to invert the interior assembly; the lock automatically detects orientation, simplifying the setup process for your front door lock.

5. Robust Security for Peace of Mind

At its core, this is a high-security deadbolt lock. Schlage is known for strong mechanical security, and the Encode Plus is ANSI/BHMA Grade 1 certified. It includes a built-in alarm that sounds if someone tries to force the door or repeatedly enters the wrong code. All user data is stored locally and encrypted, giving you true peace of mind.

Cons for Canadian Winters

Battery Life Shrinks in Cold Weather: While Schlage claims the four AA batteries last up to six months on Wi-Fi, cold temperatures can shorten that. A Canadian user found the lock’s batteries drain “a bit quickly,” which can be exacerbated by below‑freezing temperatures. Because the lock lacks a rechargeable option, you’ll need to keep spare AA batteries on hand.
No Fingerprint Sensor: Competing locks like the Yale Assure Lock 2 Touch and Aqara U100 include fingerprint readers. RedFlagDeals users noted they seldom use Home Key if a fingerprint option is available. If you prefer biometric entry, you’ll have to wait for future Schlage models or choose another lock.
Limited Auto-Lock Timer: The lock can automatically lock after 15 seconds, 30 seconds, 1 minute, or 5 minutes at most. One Canadian owner said the four-minute maximum sometimes causes the door to lock while people are coming and going and wished there was a 15-minute option.
Keypad Doesn’t Light Up Until Touched: The touchpad stays dark until you press the Schlage logo. Users found guests sometimes enter the code incorrectly on the first attempt because the numbers aren’t backlit by proximity—a minor annoyance when it’s dark outside.
Thread & Matter Still Maturing: A firmware update added Thread support, but it currently works only with Apple Home and there’s no Matter connectivity yet. If you want a lock that works across ecosystems via Matter, the Yale Assure Lock 2 and Aqara U100 are ahead.

Installing the Schlage Encode Plus: A Step-by-Step Guide

Gather Tools: You only need a Phillips screwdriver. No drilling is required for standard North American doors.
Remove Old Deadbolt: Unscrew and remove your existing deadbolt lock.
Install New Bolt: Slide the new Schlage bolt into the door edge, ensuring you’ve set it to the correct backset (2-3/8″ or 2-3/4″).
Mount Exterior Keypad: This keypad deadbolt uses Schlage’s Snap ’n’ Stay™ plate to hold the exterior keypad against the door while you attach the interior mounting plate.
Connect Interior Assembly: Plug in the cable, align the thumb turn, and secure the interior assembly. Insert four AA batteries and replace the cover.
Pair and Calibrate: Download the Schlage Home app and follow the on-screen instructions to get connected to your home’s WiFi network. The lock automatically detects whether your door is left- or right-handed.
Set Up Apple HomeKit (Optional): In the Apple Home app, scan the HomeKit code behind the battery cover to add the lock and enable the NFC tap-to-unlock feature.

Real-World Performance and Competitor Comparison

In The Verge’s long‑term test, the Encode Plus ran for two months over Wi‑Fi and still had 82% battery life remaining. Another reviewer used the lock on Thread (which consumes less power) and after three months their batteries still showed 94% capacity. For most Canadians using Wi-Fi, it’s realistic to expect 3–6 months of battery life through a cold winter.

Day‑to‑day use is convenient. The keypad is responsive, and the motor is audible but not obnoxiously loud. The ability to lock or unlock using the app is reliable. For Apple users, tapping your watch or phone is by far the fastest way to enter. However, because there’s no fingerprint reader, you must rely on codes or Home Key; if you prefer biometrics, see the competitor section below.

How the Encode Plus Stacks Up

Compared with August Wi‑Fi Smart Lock: The Encode Plus offers a keypad and doesn’t need a separate accessory. August keeps your existing deadbolt and is more discreet, but its reliance on CR123 batteries means replacements are pricier. August’s Auto‑Unlock feature is convenient but uses your phone’s geolocation and may not always trigger; the Encode Plus’ HomeKey tap is faster and more reliable.
Compared with Yale Assure Lock 2: Yale offers modular connectivity and the option of a fingerprint reader or Apple Home Key. It is rated to operate down to –30 °C—great for Canada. However, its Bluetooth auto‑unlock can be unreliable and you must purchase the correct module to get Wi‑Fi. Schlage provides Wi-Fi out of the box and Grade 1 security but lacks a fingerprint option.
Compared with Aqara U100: The Aqara smart lock U100 includes both a fingerprint reader and HomeKey plus an IP65 rating, making it attractive for cold, wet climates. It’s also cheaper. The trade‑off is that you need an Aqara hub for remote control and third‑party integrations, and some reviewers don’t like its industrial design.

The Verdict: Is the Schlage Encode Plus the Best Smart Lock for You?

The Schlage Encode Plus™ Smart WiFi Deadbolt is a formidable contender for the title of the best smart lock for a Canadian climate. It is built on a foundation of Grade 1-certified mechanical security, a legacy Schlage is famous for. Its combination of direct Wi-Fi connectivity and seamless Apple Home integration delivers a level of convenience that few rivals can match without extra hubs or modules. For households invested in the Apple ecosystem, the ability to unlock your door with a simple tap is a killer feature during a cold snap.

However, the lock is not perfect. Battery life in winter will be shorter than advertised, and there is no fingerprint reader, which some users prefer over NFC. The auto‑lock timer is limited and the keypad doesn’t light up until you touch it. If you prioritise a fingerprint reader or need Matter‑compatibility today, the Aqara U100 or Yale Assure Lock 2 Touch may suit you better and are cheaper.

Ultimately, the Schlage Encode Plus strikes an outstanding balance of security, convenience, and weather resilience. For most Canadian homes—and especially for Apple users—this smart deadbolt lock is an investment in security and convenience that will stand up to many winters to come.
