Community Reviews
The Aqara U400 is a smart lock aimed at Apple households and Matter over Thread setups, with fast hands free unlocking, keypad access, backup keys, and broad support for HomeKit, Google Home, Alexa, and Home Assistant. The Costco bundle stands out for including the M100 hub and two batteries, and the hub alone is valued at about $30. The lock is also praised for reliable auto lock and easy installation without changing existing locks. The main hesitation is price, since similar bundles are close to Amazon and some prefer cheaper AA battery models or older Schlage locks.
Common Questions (5)
Yes. The U400 supports Apple Home and UWB, so an iPhone can unlock it as you approach without needing to use the fingerprint reader most of the time. It also keeps a physical key as backup.
The Costco bundle includes the U400 lock, the M100 hub, and two batteries. The hub is a meaningful part of the value because it retails for about $30 on its own.
Yes. It works with Android and Google Home, and it can also be used in multi-lock setups. The lock is also described as Matter over Thread, so it can integrate without cloud connectivity.
The Apple Store version is described as a more premium-finish variant with more metal and a more upscale exterior. The core lock mechanism and functionality are described as essentially the same, while the Costco/Amazon version uses more plastic on the outside.
No. It is described as Matter over Thread, which works as an open standard and does not require cloud connectivity. That allows it to work with ecosystems like HomeKit, Google, Alexa, and Home Assistant.

I was originally planning to replace my Eufy smart lock with the Aqara U100, but once I saw the U400 with UWB support, I decided to go that route instead. I first ordered the U400 from Amazon for $269, but it's still unopened and I'll be returning it once the Costco order arrives.
The Costco bundle was just too good to pass up since it includes two batteries and the M100 hub. I already have an M3 hub that I picked up from Facebook Marketplace, so the M100 is really just a bonus for me.
I've also seen some confusion about whether this version is the same as the one Apple sells. My understanding is that the Apple Store version is more of a premium-finish variant, with more metal and a more upscale exterior design, while the internal lock mechanism and core functionality are essentially the same.
Someone please correct me if I'm wrong, but I believe the main difference is that the Apple version looks and feels more premium, while the Amazon/Costco version uses a bit more plastic in the exterior construction.
