The Aqara Smart Lock U200 Lite is a retrofit smart lock kit for compatible existing door hardware. It adds keyless access without drilling or replacing the whole lock, using app control, NFC sticker card support and auto-locking for everyday convenience.
Matter over Thread support helps it integrate with modern smart home platforms through a suitable Thread Border Router. The rechargeable battery design and simple retrofit installation make it a practical upgrade for homes that want smart access without a full lock replacement.
