Quick verdict: pay for the way you want to enter

The Yale YRD510-MT1 makes sense when you want to enter a code, keep a physical backup key and control the lock in an existing Matter smart home. We would put it first for a Google Home household that does not need fingerprint or phone-as-key entry.

The U400 earns its higher price when its extra ways in matter to your household. It adds a fingerprint reader, compatible digital-wallet access and UWB hands-free unlocking with supported Apple hardware. Those features can be useful every day, but check each resident’s device before buying for hands-free access.

This comparison covers the US Yale Smart Lock with Matter, YRD510-MT1, and the US Aqara Smart Lock U400. Yale Assure Lock 2, Assure Lock 2 Plus and the older Nest x Yale are different products. Their features do not carry over just because the name says Yale.

What is different at the front door?

Yale gives you a physical push-button keypad and a mechanical key cylinder. That is an appealing combination if entering a short code is already easy enough. App control adds convenience, but you do not need to make a phone your everyday key.

The U400 gives residents more choices. Someone can use a fingerprint, another person can use a PIN, and a compatible Apple user can tap a phone or watch or use hands-free approach unlocking. Both locks retain a physical key for backup.

The U400’s clearest advantage is entry convenience. It does not follow that a fingerprint reader or a longer feature list makes it more resistant to forced entry. Door condition, strike installation and sensible account security still matter. We have not security-tested either lock.

If fingerprint entry is the only upgrade you want, compare the U400 with our fingerprint smart lock shortlist before paying for features you may not use.

How does Yale work with Google Home and Yale Access now?

Yale positions this model around Google Home, with Matter support for other compatible platforms. Its current app workflow is more flexible than older reviews suggest.

In its August 4, 2026 Yale Access update, Yale says the app guides Bluetooth pairing and Matter setup, shows the lock’s Matter connections and retains access to settings and activity even when the lock is connected through Matter.

Where you manage access still changes. Without Matter, entry codes and guest access are managed in Yale Access. With Matter connections, those access-control functions are managed through the Matter controller apps. That means your choice of Google Home, Apple Home, Alexa or SmartThings affects the experience.

Do not buy on the assumption that every platform exposes identical guest schedules, alerts or door-status features. Check the specific function you need in the chosen app. A cleaner who needs a recurring weekday code is a different requirement from a family member who needs permanent access.

Yale also includes DoorSense, which can distinguish whether the door itself is open or closed when correctly installed and calibrated. Feature exposure depends on the app. A screen saying the bolt is locked is not, by itself, proof that the door is closed.

Is the U400 better for Apple users?

Yes, if you want Home Key or compatible hands-free entry. The Yale YRD510 supports Apple Home through Matter, but it does not include Apple Home Key, a fingerprint reader or UWB hands-free unlocking.

On the U400, tap-to-unlock means presenting a compatible iPhone or Apple Watch to the lock. UWB hands-free entry can recognize an authorized approach while the device stays in your pocket. These are separate capabilities with different requirements. Tap-to-unlock supports a broader set of Apple devices; check the current pairing guide for your exact phone or watch rather than using the hands-free list as a tap-access list.

Aqara’s current U400 pairing guide lists iPhone 11 or later for hands-free UWB, excluding iPhone SE, iPhone 16e and iPhone 17e. Its Apple Watch list starts at Series 6 and excludes Apple Watch SE. The guide specifies iOS 18.6 or later and watchOS 11.5 or later; keep the lock and supporting home equipment updated too.

You also need an appropriate Thread-enabled Apple home hub. Examples include HomePod mini, HomePod (2nd generation), Apple TV 4K (2nd generation) or Apple TV 4K (3rd generation, Wi-Fi + Ethernet). The third-generation Wi-Fi-only Apple TV does not provide the equivalent Thread hardware.

The practical check is household-wide: if only one person has a compatible device, everybody else still needs a useful way in. The U400’s fingerprints and PINs help cover that gap. Our Aqara U400 review goes deeper into its setup and daily-use tradeoffs.

What about Samsung and other Android phones?

A Google Home household can choose Yale without paying for Apple-specific entry features. The U400 remains relevant to Android households for fingerprint and PIN entry, plus supported smart-home integration.

The U400 also supports Samsung Wallet NFC tap-to-unlock on compatible Samsung hardware, with the required SmartThings connection and supported gateway. Aqara says Galaxy Watch is not supported. However, Aqara’s latest official Samsung update says the Samsung UWB hands-free rollout is delayed, without a revised launch date. NFC tap access should not be confused with hands-free approach unlocking.

If Samsung hands-free entry is the reason you are considering the U400, we would wait for confirmed availability rather than buy around a promised future release. For other Android devices, verify the supported app and entry method instead of assuming the Matter logo supplies a phone key.

What equipment do both locks need?

For connected Matter-over-Thread use, plan for a compatible Matter controller and Thread border router. One supported device can perform both roles. An ordinary Wi-Fi router does not automatically cover either one.

Neither of these locks has built-in Wi-Fi. Remote control relies on your chosen platform’s supporting hardware and internet connection. Local entry methods and remote app access are separate things: a stored PIN or physical key does not need the same cloud path as unlocking from another city.

For the U400’s Apple entry features, use Aqara’s documented Apple setup. For Aqara Home remote features or automations, check the current compatible Aqara hub requirements separately. Basic Matter control in one app does not guarantee access to every manufacturer setting in that app.

Before buying, identify the exact hub already in your home, confirm that it supplies Thread for the platform you intend to use, and check coverage near the door. Our Matter smart lock guide covers the broader choices.

Is the U400 worth the extra $80?

At the manufacturer prices checked for this comparison, Yale was $189.99 and the U400 was $269.99. That is an $80 difference for the locks alone. Both official stores showed available variants, but stock and offers can change.

With compatible hub equipment already owned, the decision is mainly whether fingerprints and supported phone/watch entry are worth that premium. For a busy front door, we think that can be a reasonable upgrade. For a side door used occasionally, Yale’s keypad may cover the job just as well.

Starting from scratch changes the arithmetic. Add the price of any required hub and installation help to the actual lock offer. Do not assume an Amazon listing includes a hub or spare battery because a different U400 bundle does. Check the selected package, finish and included parts.

Yale uses four AA alkaline batteries and advertises up to 12 months in Matter operation. Aqara uses a removable rechargeable pack and advertises up to six months. These are different manufacturer estimates under different conditions, so they do not establish that Yale lasts exactly twice as long in your home.

Choose the maintenance routine you prefer: replacing AAs or charging a removable pack. The U400 also provides exterior USB-C emergency power. That powers the lock electronics; it does not remove the need for an authorized entry method. Keep the mechanical backup key somewhere accessible outside the locked home.

If minimizing the total spend is the priority, our smart locks under $200 guide includes options with different connectivity requirements.

Will either fit your existing door?

Both are replacement deadbolts, rather than interior-only retrofit devices. Check door thickness, bore size, backset and interior clearance against the exact model’s installation guide. Also check that the existing bolt moves freely without having to lift or push the door.

Yale lists compatibility with doors 1⅜ to 2¼ inches thick, a 2⅜- or 2¾-inch backset, and 2⅛- or 1½-inch face bores. Use Yale’s installation information for the complete measurements and conditions. Check the U400 separately against Aqara’s specifications and installation guide; a fit claim for one lock does not establish a fit for the other.

Resolve a binding bolt before adding a motorized lock. If you rent or have restrictions on exterior hardware, get the necessary permission before replacing the deadbolt.

Which one should you buy?

Choose Yale YRD510-MT1 if you want push-button codes, a backup key and Matter control, especially in an existing Google Home setup. Its lower price makes sense when those functions are enough.

Choose Aqara U400 if a fingerprint reader or compatible Apple Home Key and hands-free entry will get regular use. It is the more versatile entry system here, provided your household’s devices and supporting hardware qualify.

Pause before buying either if you want remote control with no extra supporting hub and have only an ordinary Wi-Fi router. Work out the complete setup first. The best choice is the one that covers the ways your household actually enters, without buying equipment for features you cannot use.

Frequently asked questions

Does Yale Smart Lock with Matter support Apple Home Key?

No. Yale YRD510-MT1 can work with Apple Home through Matter, but it does not have Home Key tap entry or UWB hands-free unlocking. Other Yale models have different features, so check the exact product name.

Can both work in Google Home?

Both offer Matter-over-Thread integration with a compatible setup. That does not mean every lock feature appears in Google Home. Verify the guest-code, notification and automation functions you need before choosing.

Does either need Wi-Fi inside the lock?

Neither has built-in Wi-Fi. Their Matter connection uses Thread with supporting hardware. Remote access depends on the chosen smart-home platform; local PINs and physical keys serve a different purpose.

Can I still use Yale Access after adding Matter?

Yale’s August 2026 update says settings, activity and Matter-connection management remain available in Yale Access. When the lock is connected to Matter, entry codes and guest access are managed through Matter controller apps. Update the app and follow current setup guidance.

Is U400 hands-free unlocking ready for Samsung phones?

Aqara’s latest official update says Samsung UWB hands-free unlocking is delayed. Supported Samsung Wallet NFC tap entry is available. Do not treat those as the same feature or assume a release date for hands-free support.
