Aqara EL-D03D-B is a Bluetooth smart door lock in black designed for residential or small-office doors. It runs on a 7.4 V Li‑Ion battery and has compact dimensions (152.5 × 62.3 × 60.6 mm).

## Long description

The Smart Aqara EL-D03D-B (U200 Lite) is a Bluetooth smart door lock in black designed for residential and small-office doors. It fits over existing cylinders that have an Emergency Function and provides keyless access management with multiple unlocking options, Matter over Thread connectivity for ecosystem integration, and a rechargeable Li‑ion battery for long runtimes. Its compact dimensions make it suitable for standard door preparations without complex installation.
Advantages
The lock supports Matter over Thread for seamless integration with major smart home ecosystems while preserving full functionality. Multiple unlocking methods are available — Bluetooth, NFC sticker card, remote and voice unlocking — giving flexible access options. Quiet, Standard and Fast modes let you choose quieter nighttime operation or quicker daytime response. Auto-lock on close uses a built-in gyroscope to secure the door automatically, and a pull-spring feature retracts the latch on unlock to allow hands-free entry. The unit is powered by a rechargeable 2000 mAh Li‑ion battery with a low-battery alert to avoid unexpected lockouts, and installation requires no major modifications when the existing cylinder includes an Emergency Function.
Suitable for
Residential front and interior doors
Small office doors with standard cylinder preparations
Homes where quiet nighttime unlocking is preferred
Situations requiring hands-free or hygiene-focused entry

How to use
Install the Smart Aqara EL-D03D-B over the existing door lock cylinder that has an Emergency Function following the included installation instructions; no complex door modifications are required. Pair the lock with a smartphone or hub via Bluetooth and, if desired, integrate it into a Matter-supported ecosystem using a Thread Border Router. Choose the preferred unlocking methods in the companion app (Bluetooth, NFC sticker card, remote or voice). Use Quiet, Standard or Fast mode settings to adjust unlocking behavior; the gyroscope-enabled auto-lock engages when the door is closed. Recharge the built-in battery before it reaches a critically low level, guided by the low-battery alert in the app.
Usage recommendations
For reliable operation, confirm your door cylinder supports Emergency Function before installation, keep the companion app and firmware up to date, and recharge the battery when the low-battery alert appears. Use Quiet Mode at night for reduced noise and enable Matter over Thread when a compatible Thread Border Router is available to integrate the lock into your smart home ecosystem.
