No community reviews yet.
A full replacement supplies its own bolt and keyway. A retrofit keeps the existing cylinder and key. Check the documented bore sizes against your door.
The manual recommends enlarging a 38 mm bore to 54 mm on a solid door.
Published protocol support is a manufacturer statement, not a tested interoperability or security result. A required controller sold separately is not included.
Battery-life figures are manufacturer estimates under stated usage assumptions, not measured results for your door.
The manufacturer estimates up to six months per charge; UWB is disabled automatically below 8% battery.
Silver is the same package in another colour. Bundles with a Hub M100, a second battery, doorbell or camera hubs are separate offers with different model codes. A Thread-enabled Matter controller is required for ecosystem use and is not in this box. Price and stock are not recorded.

| Questions to check before buying | This is the shipping U400 (DL-D06E), not the CES 2026 announcement; door thickness is not published, so fit must be checked with Aqara support before purchase. Matter, Thread, UWB and Home Key support are manufacturer statements that depend on a separately sold controller; they are not tested interoperability or security results. |
