Overview
The silver U300 is the lighter-finish twin of the black model — same Matter and Home Key platform for doors that need a lever lock and brighter hardware. Measure frame clearance carefully; the exterior unit is wider than some older knobs.

Product details
The Aqara U300 silver finish matches chrome and stainless door furniture while keeping the same Matter and Home Key feature set as the black model. Unlock with Home Key, handle fingerprint (up to 50), keypad, NFC, Bluetooth or keys. IPX4 weather resistance and cold-weather operation suit sheltered outdoor entries. Check exterior unit width against your door frame and trim — some narrow frames need extra clearance. Pair with an Aqara hub where you want deeper automations.
