The verdict

Why it scored a 77

At $139.99, the Aqara Smart Lock U100 is the cheapest route to Apple Home Key, letting an iPhone or Apple Watch tap to unlock even with a dead phone. Features scores 82 for that plus fingerprint, keypad, NFC, and a physical key, and Value sits at 82. Reliability is 83 across 2,500 ratings. The real caveat is the hub: remote access and Alexa or Google control require an Aqara Zigbee hub sold separately for roughly $50, which pushes the true price toward $185 for non-Apple households. Warranty drags at 55 with one year. It is for an Apple Home household that wants Home Key without flagship prices.

Who it's for

Should you buy the Aqara Smart Lock U100?

The Aqara Smart Lock U100 is the deadbolt for Apple households that want to tap an iPhone or Apple Watch to unlock the door. At $139.99 it scores 77, and Apple Home Key support is the reason to buy it; it is the only lock in this category that offers it. Fingerprint, keypad and key round it out. The problem is that remote access and Alexa or Google control need an Aqara Zigbee hub, which pushes the true cost toward $185. If you are not on Apple Home, the Ultraloq U-Bolt Pro WiFi (86) does more for less.

What stands out

Where it earns its score

  • Apple Home Key. Tap an iPhone or Apple Watch on the lock, and it works even with a dead phone thanks to Express Mode power reserve.
  • Plenty of other ways in. Fingerprint reader for 50 prints, keypad, app codes, NFC and a physical key.
  • Reliability is the top factor at 83. The built-in gyroscope handles auto-lock, and there is USB-C emergency power on the outside if the batteries die.
  • Good battery life. Four AA batteries run up to eight months.
Before you buy

What to know first

  • The hub is not in the box. Remote access, Alexa and Google need an Aqara Zigbee hub at roughly $50. Ultraloq and Schlage have Wi-Fi built in.
  • Warranty is the weakest factor. One year from Aqara scores 55, against lifetime mechanical coverage on Ultraloq and Schlage.
  • Quality is 72. The hardware is fine but not in the Schlage class, and Aqara's app is more complex than most.
Bottom line

Our verdict

The Aqara Smart Lock U100 scores 77, Fair Buy, and it is the pick for anyone committed to Apple Home who wants Home Key at a reasonable price. Everyone else should buy the Ultraloq U-Bolt Pro WiFi (86, $129.99), which has built-in Wi-Fi, ANSI Grade 1 hardware and a lifetime mechanical warranty for less money than the Aqara plus its hub.

FAQ

Questions buyers ask

Does the Aqara U100 need a hub?

For Apple Home Key, fingerprint and keypad, no. For remote unlocking, Alexa or Google control, yes: it needs an Aqara Zigbee hub sold separately for about $50.

Does Apple Home Key work if my iPhone battery is dead?

Yes. Express Mode uses the iPhone's power reserve so the U100 can still read the key for several hours after the phone shuts down.

Is the Aqara Smart Lock U100 worth it without Apple devices?

Not really. Its main advantage is Home Key. Android or mixed households get more from the Ultraloq U-Bolt Pro WiFi, which scores 86 and needs no hub.
