Aqara U50 vs. U100: Is Fingerprint Entry Worth the Upgrade?

Buy the Aqara U100 if people in your household will regularly use its fingerprint reader. Buy the U50 if Apple home key and keypad codes already cover the way everyone enters. Both offer Apple tap entry, so paying more for U100 is not necessary just to unlock with an iPhone or Apple Watch.

The current bundles make the decision closer than the standalone prices suggest. Aqara lists U50 at $149.99 and U100 at $189.99, a $40 difference. With an M100 hub included, the displayed prices are $152.99 and $186.99: a $34 upgrade. The U100 bundle is actually $3 cheaper than its lock-only listing.

These are US prices checked November 7, 2026, not guaranteed checkout totals. This comparison covers the U50 and U100 replacement deadbolts, not the retrofit U200 or hands-free U400.

When fingerprints are worth the upgrade

U100 makes the most sense for a mixed household: an iPhone owner can use home key, an Android user can use a fingerprint, and a visitor can use an appropriate PIN. It also gives you a phone-free way in when you step outside without a watch or phone.

The relevant question is how often that extra entry method will be used. If everyone already taps an Apple Watch at the door, the fingerprint reader may sit idle. If someone dislikes entering codes or regularly leaves their phone indoors, it can be the feature that makes the lock convenient.

At the current bundle prices, that choice costs $34 once. It is a modest premium for a frequently used feature, but it does not make U100 a universally better purchase. U50’s lower price and supported rekeying route may matter more to your household.

Set U100 up in Aqara Home to configure fingerprints and its model-specific features, then add the supported Apple integration if wanted. Its user manual warns that Apple-Home-only setup does not provide fingerprint configuration. Aqara says fingerprints are stored locally; we have not measured recognition accuracy or unlocking speed.

Apple home key does not require the U100

Both models support Apple home key. You add the compatible lock to Apple Home and use a supported iPhone or Apple Watch to tap at the reader. A fingerprint sensor is not part of that process. Aqara documents U50’s native Apple support in its U50 introduction.

Tap entry at your door is different from unlocking across town. For remote Apple Home control, plan around an appropriate Apple home hub and the supported connection to the lock. An Aqara hub handles a different route: remote management through Aqara Home.

Apple’s home-hub setup guide explains remote access and automation requirements. Do not assume that buying an M100 replaces a HomePod or Apple TV for every Apple Home feature, or that owning a HomePod supplies Aqara’s remote administration features.

Compare the complete package price

The table shows displayed Aqara US hardware prices. It excludes tax, shipping, installation, locksmith work, replacement batteries and any missing USB power adapter. The bundles include the named lock and one M100 hub; they are not all-inclusive installation packages.

Purchase	U50	U100, Gray
Lock alone	$149.99	$189.99
Lock + separate $29.99 M100	$179.98	$219.98
Advertised lock + M100 bundle	$152.99	$186.99
Required lock subscription, 1 year / 3 years	$0 / $0	$0 / $0

Price sources: U50, U100, M100, U50 + M100 bundle and U100 + M100 bundle. Compare the exact finish, package and current checkout price; discounted bundles can change.

Buying separately currently adds $26.99 to the U50 bundle price or $32.99 to the U100 bundle price. Even if you already own a compatible Aqara hub, check the U100 bundle because its displayed price is lower than the standalone lock. You do not have to install an unnecessary second hub.

Aqara’s smart-lock FAQ says its locks do not require a subscription. There is no mandatory lock-service fee to multiply across three years. The hardware subtotal therefore stays the same before batteries and other ongoing household costs; that is not a promise of zero maintenance spending.

M100 needs USB-A power at 5V/0.5A, and its listed box contains the hub and manual, not a wall adapter. Budget for a suitable powered USB port or adapter in a useful location near the lock. Check the M100 specifications and setup guidance before treating the bundle as ready to plug into a wall outlet.

Buy a hub for a specific job

• Local entry: keypad codes, mechanical keys and the lock’s supported local features do not require buying an Aqara hub. U100 adds local fingerprint entry. Nearby Aqara Home setup uses Bluetooth.
• Aqara remote management: add a compatible Aqara hub, such as the M100 supplied in the named bundles, plus suitable home network and internet service.
• Apple Home remote control: use the documented Apple home-hub route. Price only equipment you are missing.
• Matter integration: these are Zigbee/Bluetooth locks bridged through compatible Aqara equipment. They are not native Thread locks. A Thread border router on its own cannot replace that bridge; the destination platform also needs its supported Matter-controller setup.

The U100 specifications and U50 specifications identify the radios. For a fuller breakdown of the remote-access choices, see our U100 hub buying guide. Neither lock becomes a direct-Wi-Fi model because a store listing says “remote control.”

Door fit and backup keys can decide this first

Both replace a single-cylinder deadbolt. Aqara’s documented installation requirements include a 35–55mm wooden door, 60mm or 70mm backset and a 54mm bore. Check the U50 installation specifications and U100 installation requirements before ordering. Do not assume an unusual, metal or multipoint door fits without confirmation.

Measure the interior clearance and check that the bolt moves freely with the door closed. A smart motor does not correct an out-of-alignment strike plate. If you rent, obtain permission for a replacement lock rather than assuming that battery-powered installation is automatically allowed.

U50 has a useful, specific advantage for backup-key planning: its manual documents an SC1 five-pin cylinder that a professional can rekey. That does not mean every existing key fits. Ask a locksmith whether your key and the cylinder are compatible and include the labor in the price comparison.

We did not find equivalent manufacturer-supported U100 rekeying instructions in the sources reviewed. If matching an existing key is essential, confirm the exact option with Aqara before buying U100. Do not infer that capability merely because both locks come with mechanical keys.

Both include four AA batteries and two keys. The USB-C port supplies emergency power; it does not turn the AA batteries into a rechargeable pack or bypass the normal unlocking credentials. Arrange backup access before you need it.

Our buying recommendation

Choose U50 if PINs and Apple tap entry cover everyday use, especially when its documented rekeying route fits your household. Choose U100 if at least one regular user will rely on fingerprints. At today’s $34 bundle gap, we would pay the extra for that daily convenience.

Before checkout, make three decisions: confirm door fit, decide which app needs remote access, and compare the lock-only and complete-kit prices. Those checks are more useful than buying the higher model number by default.

Frequently asked questions

Does the Aqara U50 support Apple home key without fingerprints?

Yes. U50 supports Apple home key as well as keypad and mechanical-key entry. U100 adds a fingerprint reader; it is not required for Apple tap entry. Use compatible Apple devices and follow the model’s setup instructions.

Does a HomePod mean I can skip the Aqara hub?

Possibly, if your goal is the supported Apple Home route rather than Aqara remote management. A HomePod can serve as an Apple home hub, but it does not replace an Aqara bridge for these locks’ Zigbee/Matter integration or supply every Aqara Home feature. Identify the app and function before buying equipment.

Can I keep using my current physical key?

Do not assume so. These locks replace the existing deadbolt. U50 has documented professional rekeying support for its SC1 five-pin cylinder, subject to key compatibility. Confirm U100 options with Aqara and a locksmith. Neither is a retrofit motor that simply leaves your existing exterior cylinder in place.

What happens if the internet or lock batteries fail?

An internet outage can stop remote commands while powered local entry methods remain available. Depleted lock batteries are a separate problem: use the mechanical key or the documented USB-C emergency-power procedure with an authorized entry method. Keep the key accessible outside the locked home.

Is a subscription required after buying either lock?

No mandatory lock subscription is listed for U50 or U100. The purchase budget still needs any required hub or Apple equipment, installation and batteries. Optional third-party services are separate purchases and should not be assumed included.
