Choose the Entry Method First
Keypad access is useful when several people need entry without carrying a key. The Schlage Encode Plus Smart WiFi Deadbolt Lock supports up to 100 access codes, while the Yale WiFi Smart Lock Deadbolt offers unlimited codes that you can share, schedule, or revoke through its app.
Biometric entry reduces the need to remember a code. Yale uses a fingerprint reader, while the eufy Security Video Smart Lock FamiLock S3 Max uses palm vein recognition and stores that data locally on the lock. That makes the eufy model especially distinctive for households wanting a physical, app-free entry option.
Pro Tip: Choose the entry method that every regular household member can use confidently, then keep the backup method accessible to the person responsible for maintenance.
Match the Lock to the Door Routine
Remote control matters if you manage deliveries, visitors, cleaners, or short-term guests. Schlage lets you manage access codes, view lock history, receive notifications, and control the lock from anywhere through its app and built-in WiFi. Yale also connects directly to WiFi without a hub or bridge and supports real-time alerts.
The eufy model adds a 2K HD camera, a video doorbell with a 150-degree head-to-toe view, visitor alerts, and a rear lock video screen. That combination suits a front entrance where you want to see visitors or packages as well as control the deadbolt.
| Device type | Distinctive feature | Best fit |
|---|---|---|
| Keypad deadbolt | Up to 100 codes | Apple Home households |
| Video smart lock | 2K camera and screen | Visitor monitoring |
| Fingerprint deadbolt | Unlimited scheduled codes | Rentals and families |
If you are unsure whether a lock replaces your existing hardware cleanly, review what a strike plate does. Door alignment and a properly seated deadbolt affect everyday operation more than an impressive feature list.
Check Power, Connectivity, and Compatibility
All three products are designed for connected access, but their ecosystems differ. Schlage works with Apple HomeKit, Apple home keys, Alexa, and Google Assistant. Yale supports 2.4 and 5 GHz WiFi, Apple Home, and the Yale Access app in the US and Canada.
eufy supports Matter connections with Apple Home, Google Home, Alexa, and SmartThings, though camera streams are not supported through Matter. Full camera features require the eufy app, and the lock is compatible with HomeBase 3 rather than HomeBase 2.
Before You Mount It: Do not assume every smart-home platform carries every feature. Confirm whether you need the lock app for camera streams, guest management, or alerts before choosing a shared household setup.
Battery planning also differs. The eufy lock has a rechargeable battery rated for up to four months of full functionality, plus four AAA batteries for an additional month of essential functionality. Yale provides low-power alerts, and Schlage requires no hardwiring during installation.
Expert Examined
From Dana Whitfield
I keep seeing households choose a lock for its app before checking who will actually use the keypad or fingerprint reader. The better approach is to decide the daily entry habit first, then verify door fit, WiFi coverage, and the backup power plan.

Certification gives you a useful durability reference, but it does not replace correct installation. Schlage carries the highest residential security, durability, and finish rating from BHMA industry experts. The eufy lock is BHMA Grade 1, while Yale is BHMA Grade 2 and designed for temperatures from -22°F to 140°F.
Remote history and alerts help you keep track of access, but you should still know how to restore access if a phone, battery, or network becomes unavailable. Keep the physical backup method in a secure place, and use the advice in how to reset a smart lock before an emergency occurs.
For broader account protection, the guidance on whether smart locks can be hacked is worth reading. Use strong account credentials, limit shared permissions, and remove temporary access when it is no longer needed.
Which Lock Fits Your Household
I would point Apple Home households toward the Schlage Encode Plus Smart WiFi Deadbolt Lock, particularly if tapping an iPhone or Apple Watch is more convenient than entering a code. Its built-in WiFi, lock history, customizable notifications, alarm, and capacity for 100 access codes also suit a busy primary entrance.
I would put the eufy Security Video Smart Lock FamiLock S3 Max on a front door where visitor visibility is as important as entry control. Its palm vein reader, rear screen, 2K camera, wide viewing angle, local storage, and backup AAA battery set make it the most feature-rich choice for families monitoring arrivals and packages.
For rentals, extended families, or anyone sharing access frequently, I would choose the Yale WiFi Smart Lock Deadbolt. Fingerprint access, unlimited scheduled codes, Auto-Unlock, DoorSense, and direct WiFi control fit changing guest permissions without requiring a hub.
The Bottom Line
The mistake many buyers make is treating all smart locks as interchangeable. Entry method, camera needs, household platform, door compatibility, and backup power determine whether a model feels simple or frustrating after installation.
If you do one thing first, identify who needs access and how they will enter on an ordinary day. Then verify the door measurements, WiFi requirements, and emergency power method before choosing the feature set.
FAQs
Fingerprint and palm vein access reduce code sharing and remembering, while a keypad works well for guests, children, service providers, and rentals. Choose the method that matches the people using the door most often, and confirm that a backup entry method is available. The Schlage and Yale models provide built-in or direct WiFi connectivity for remote control. The eufy lock supports Matter and the eufy ecosystem, with full camera features requiring the eufy app and HomeBase 3 compatibility rather than HomeBase 2. Check that the door closes fully and that the deadbolt aligns smoothly with the strike plate. Verify door thickness and backset requirements, then follow the manufacturer instructions before relying on remote access or Auto-Lock. BHMA grading indicates performance categories such as security, durability, and finish under an industry standard. It helps compare hardware construction, but it does not guarantee correct installation, network security, or a suitable fit for every door. Battery alerts give you time to replace or recharge the power source. Keep the stated backup method available, such as a physical key or emergency batteries, and avoid waiting until the lock stops responding before maintaining it.Should I choose a fingerprint, palm vein, or keypad smart lock?
