Schlage Encode Plus vs Yale Assure Lock 2: Smart Lock Face-Off
Last updated September 2026
Quick answer: The Schlage Encode Plus wins on raw security, with an ANSI Grade 1 deadbolt, a built-in 90dB alarm, and Apple Home Key support. The Yale Assure Lock 2 wins on flexibility, letting you choose WiFi, Z-Wave, Zigbee, or Matter connectivity and swap the module later. Choose Schlage if break-in resistance is your top concern; choose Yale if you want a lock that adapts to whatever smart home platform you use next.

The Verdict: Which Should You Buy?
If you live in an area with elevated break-in risk, rent out a property you cannot monitor closely, or simply want the toughest deadbolt money can buy, the Schlage Encode Plus is the safer pick. Its ANSI Grade 1 rating is the highest residential security certification that exists, and the hardened steel bolt and reinforced strike plate are built to resist the kind of brute-force attacks a Grade 2 lock cannot.
Check the Schlage Encode Plus price on Amazon if security-first hardware matters more to you than connectivity options.
If you are not sure which smart home ecosystem you will settle on, or you already have a mix of Z-Wave and Zigbee devices from a system like SmartThings or Ring Alarm, the Yale Assure Lock 2 is the more future-proof choice. Its swappable module means you are never locked into one wireless standard, and with Matter support already available, it will keep working with whatever hub or voice assistant your household adopts next.

Security: ANSI Grade 1 vs Grade 2
The single biggest difference between these two locks is their ANSI/BHMA security grade. ANSI Grade 1 is the highest residential rating available and requires the deadbolt to withstand more force, more strikes, and more lock-picking attempts than Grade 2 hardware. The Schlage Encode Plus is one of the few smart locks on the market that carries this rating, thanks to a hardened steel bolt, a reinforced strike plate, and a pick-resistant cylinder.
The Yale Assure Lock 2 carries a Grade 2 rating, which is still solid, mainstream residential security and is what most smart locks (including many competitors) ship with. For the vast majority of homes, Grade 2 hardware is more than adequate. The Grade 1 difference matters most if you live in a higher-crime area, own a rental property with a history of forced entry, or simply want the strongest lock available regardless of price.
Schlage also builds in a physical layer of protection that Yale does not offer: a 90dB built-in alarm that can detect and alert you to tampering or forced-entry attempts at the door itself, independent of any connected security system.
Connectivity: Fixed WiFi vs Modular Everything
The Encode Plus keeps things simple with built-in WiFi, meaning it connects directly to your router with no hub or bridge required. That is convenient out of the box, but it also means you are committed to WiFi as your only wireless option.
The Assure Lock 2 takes the opposite approach. At purchase, you choose a WiFi, Z-Wave, Zigbee, or Matter module, and Yale sells replacement modules if you want to switch protocols later without buying a new lock. This matters more than it sounds: a Z-Wave module lets the lock talk directly to a hub like SmartThings or Ring Alarm without WiFi congestion, while a Matter module future-proofs the lock against the industry’s shift toward a single smart home standard. If you have read our guide to the Matter protocol and what it means for home security, you already know why that flexibility is worth paying for.
Unlock Methods and Access Codes
Both locks offer touchscreen keypads, smartphone app control, and a physical key as a backup, but they diverge on the extras. The Schlage Encode Plus supports Apple Home Key, which lets you unlock the door by tapping an iPhone or Apple Watch against the keypad, and it still works via Express Mode even if your phone battery is dead. That is a genuinely useful feature for anyone already deep into the Apple ecosystem, and it pairs well with the setup described in our HomeKit security system guide.
The Yale Assure Lock 2 does not offer Apple Home Key, but it wins on sheer code capacity: 250 unique entry codes compared to Schlage’s 100. That difference matters for larger households, short-term rental hosts, or anyone managing frequent dog walkers, cleaners, or contractors who each need their own temporary code.
Neither lock includes a fingerprint sensor. If biometric unlocking is a priority for you, our best fingerprint door locks guide covers dedicated options like the Eufy Smart Lock Touch that neither Schlage nor Yale currently match.
Installation, Battery Life, and Daily Use
Both locks install in 10-15 minutes with a screwdriver and no wiring, and both run on four AA batteries. Yale edges out Schlage slightly on battery life (8-12 months versus 6+ months), though real-world results depend heavily on how often the lock is used and whether WiFi or a lower-power protocol like Z-Wave is handling connectivity.
Day to day, the Assure Lock 2’s One-Touch Locking (tap any key to lock) and 30-second auto-relock are convenient for households that forget to double-check the door. The Encode Plus counters with its own auto-lock and a fingerprint-resistant touchscreen that reduces the risk of an intruder reading smudge patterns to guess your code.
Whichever lock you choose, make sure the rest of your smart home network is locked down too. A smart lock is only as secure as the WiFi it connects to, so it is worth reading our guide on how to secure your smart home WiFi network before installation day.
Price and Value
The Yale Assure Lock 2 has a wider price range, from about $159 for the base WiFi module up to $259 for Matter or Z-Wave configurations, giving you room to pick the connectivity tier that fits your budget. The Schlage Encode Plus sits at a fixed price point around $279, which reflects its Grade 1 hardware and built-in alarm.
If budget is the deciding factor and you do not need the absolute highest security rating, the Yale Assure Lock 2 in its base WiFi configuration delivers most of the smart lock experience for less money. If you are comparing total cost of ownership against a full alarm system, our guide on how much a home security system costs puts a smart lock’s price in perspective against monitored alternatives.
Common Compatibility and Installation Issues
Before you buy either lock, check the physical dimensions of your door. Both the Schlage Encode Plus and Yale Assure Lock 2 are designed to fit standard door prep with a 2-1/8 inch crossbore and a backset of either 2-3/8 or 2-3/4 inches, which covers the vast majority of North American residential doors. If your door uses a narrower European-style backset, neither lock will fit without additional hardware, so measure first.
A second common issue is door alignment. Both locks rely on a motor to retract and extend the deadbolt, and a door that has settled or shifted over time can bind the mechanism, causing the motor to strain or the lock to report a jammed state through the app. If your existing manual deadbolt already feels stiff or requires you to lift the door handle to align the bolt, address that alignment problem before installing either smart lock, since neither the Encode Plus nor the Assure Lock 2 will operate reliably on a misaligned door.
Wireless interference is worth planning around too. The Encode Plus depends entirely on WiFi, so a router placed far from the front door, or a mesh network with a weak signal at the entryway, can cause missed remote commands and delayed notifications. The Assure Lock 2 sidesteps this risk if you choose the Z-Wave or Zigbee module, since those protocols route through a nearby hub rather than competing for WiFi bandwidth with every other device in the house.
Warranty and Long-Term Support
Schlage backs the Encode Plus with a lifetime limited mechanical and finish warranty plus a three-year electronics warranty, reflecting the company’s more than a century of experience manufacturing physical door hardware. That is a meaningful guarantee if you are paying a premium for Grade 1 security and expect the lock to outlast several phone upgrades and smart home overhauls.
Yale’s warranty terms are typically shorter on electronics, which is a reasonable trade-off given the lower upfront cost and the ability to replace just the connectivity module rather than the entire lock body if a wireless standard becomes obsolete. In practice, this means the Assure Lock 2 can be cheaper to keep current over a five-to-ten-year horizon, since you are not discarding a working deadbolt just to gain a new radio.

Frequently Asked Questions
Is the Schlage Encode Plus more secure than the Yale Assure Lock 2?
On paper, yes. The Encode Plus carries an ANSI Grade 1 rating, the highest residential security certification, while the Assure Lock 2 carries Grade 2. Grade 2 is still solid protection for most homes, but Grade 1 hardware is built to resist more force and more sophisticated lock-picking attempts.
Can I switch the Yale Assure Lock 2 connectivity type after buying it?
Yes. The Assure Lock 2 uses a modular design, so you can start with WiFi and later swap in a Z-Wave, Zigbee, or Matter module without replacing the entire lock, as long as you purchase the compatible module separately.
Does either lock work without WiFi?
Both can operate on Bluetooth alone for local app control, but you will lose remote locking, unlocking, and push notifications without an internet connection. The Assure Lock 2’s Z-Wave or Zigbee modules can connect through a compatible hub instead of relying on WiFi directly.
Which lock has better battery life?
The Yale Assure Lock 2 is rated for 8-12 months on four AA batteries, compared to 6+ months for the Schlage Encode Plus. Actual battery life on both locks depends on usage frequency and which wireless connection method is active.
Do I need a professional installer for either lock?
No. Both the Schlage Encode Plus and Yale Assure Lock 2 are designed for DIY installation on a standard door, typically taking 10-15 minutes with just a screwdriver, since both replace or retrofit an existing deadbolt.
