Which Aqara U-series locks use Matter over Thread and which use Zigbee, what each needs per platform, and where Home Key and UWB fit.

Each cell is a sourced record; requirements and limits per device are listed below the article. "Unknown" means no source we accept states it either way.
What you need
- U200, U300, U400: a Thread border router for the platform you use; no Aqara hub needed for Matter.
- U100: an Aqara Zigbee 3.0 hub for remote unlock and automations, and a Matter-capable Aqara hub for Matter platforms.
- Home Key on any U-series lock: Apple Home with a home hub for sharing and remote use; U400 hands-free needs a Thread-enabled Apple home hub.
The U-series splits into two technical families, and the split decides everything else. The U200, U300 and U400 are Matter over Thread locks that work with any Matter platform through a Thread border router. The U100 and U50 are Zigbee locks that pair with Apple Home directly but depend on Aqara hubs for the other platforms.
The five models
| Model | Model numbers (US) | Radios (Aqara spec) | Matter | Home Key | Form |
|---|---|---|---|---|---|
| U400 | DL-D17D, DL-D15D; kits with Hub M100: DL-D06D, DL-D16D | Thread, UWB (per product page) | Certified 16 Dec 2025 (Matter 1.4) | Yes, plus UWB hands-free | Deadbolt replacement, rechargeable Li-ion |
| U300 | DL-D02D | Thread, Bluetooth, NFC | Certified 4 Jun 2024 | Yes (Aqara Home Key list) | Lever-style, 4× AA |
| U200 | EL-D02D, EL-D02E | Thread, Bluetooth 5.1, NFC | Certified 1 Jul 2024 | Yes (Aqara Home Key list) | Retrofit on existing deadbolt, separate keypad |
| U100 | — | Zigbee (per product page) | Only through a Matter-capable Aqara hub | Yes | Deadbolt replacement, AA |
| U50 | DL-D05D | Zigbee, Bluetooth 5.0, NFC | Not documented | Listed by Aqara | Deadbolt replacement, 4× AA |
Do not collapse the U200 and the U200 Lite. The CSA lists a separate “Smart Lock U200 Lite” (product ID 0x2807) alongside the U200 (0x2802). This page covers the U200 only.
By platform
- Apple Home. All five work. The Thread models join through Matter, and Home Key is Aqara’s addition on top; the Zigbee models pair through HomeKit. The U400 adds UWB hands-free unlock, which Aqara says needs a Thread-enabled Apple home hub such as a HomePod mini or Apple TV 4K. Details: Apple Home Key smart locks.
- Google Home, Alexa, SmartThings. On the U200, U300 and U400 these come through Matter and need a border router on that platform’s side. On the U100 they come through Aqara’s Matter bridge, so you need the hubs. For the U50 we found no Aqara statement on bridging, so we record those platforms as Unknown.
- Samsung Wallet. Aqara says the U400 supports Samsung Wallet’s Digital Home Key when connected through SmartThings.
- Home Assistant. The U200, U300 and U400 join the Matter integration directly. The U100 is reachable through an Aqara hub’s Matter bridge. Keypad code management over Matter is the open question; see Matter smart locks in Home Assistant.
Regional versions
The model numbers above come from Aqara’s US pages. Aqara sells the U200 on its EU store as well. We have not verified EU or UK model numbers or feature differences, so this page does not claim any. Confirm the model number on the box against the market you buy in.
Limits Aqara itself states
- U400: “a Thread-enabled Matter Controller of this ecosystem is required” for each Matter platform.
- U100: door status and logging were listed as “available soon” on the product page when we checked.
- U400: Aqara calls it “Aliro enabled” and says UWB unlock “will extend” to other ecosystems. That is a plan, not a current certification; see Aliro explained.
Known limitations
- Aqara Smart Lock U400: UWB hands-free unlock works with select iPhone and Apple Watch models and requires a Thread-enabled Apple home hub (HomePod mini or Apple TV 4K, per Aqara).
- Aqara Smart Lock U400: Aqara states a Thread-enabled Matter controller of the chosen ecosystem is required.
- Aqara Smart Lock U300: Platform support comes from Matter certification; Aqara does not publish a per-platform feature list for this model.
- Aqara Smart Lock U300: Keypad PIN management over Matter depends on the lock exposing Matter user-management features; check the Get lock info action before relying on it.
- Aqara Smart Lock U200: Platform support comes from Matter certification; Aqara does not publish a per-platform feature list for this model.
- Aqara Smart Lock U200: Keypad PIN management over Matter depends on the lock exposing Matter user-management features; check the Get lock info action before relying on it.
- Aqara Smart Lock U100: An Apple home hub is required for remote unlock and HomeKit automations (per Aqara).
- Aqara Smart Lock U100: Aqara: built on Zigbee; Matter support requires a Matter-supported Aqara hub plus a Matter controller.
- Aqara Smart Lock U100: Aqara lists door status and logging as "available soon" on the product page.
- Aqara Smart Lock U50: Aqara lists Apple Home and Home Key support; it does not state hub requirements for the U50 on the pages we checked.
- Aqara Smart Lock U50: The U50 spec sheet lists Zigbee, Bluetooth 5.0 and NFC. We found no Aqara statement on which hubs bridge it to this platform, so this cell stays Unknown.
