Aqara U200 Adjustable Cylinder

The Aqara AL-D04E is a modular, adjustable locking cylinder specially designed to upgrade or complement your Aqara smart lock (e.g. the U200). Engineered for flexibility and security, the AL-D04E easily adapts to a wide range of European door thicknesses while providing robust protection with anti-tamper features.

• Adjustable Length (Modular Design)
  The cylinder can be precisely sized to your door: the external side can extend between 32 mm and 67 mm; the internal side between 30 mm and 65 mm. This gives you a total adjustable length range of approximately 62 mm to 132 mm, allowing combinations like 30/32, 35/35, 40/40, etc.
• High Security & Durability
  Built from durable metal alloys with robust internal components, the AL-D04E includes features like drill resistance, tamper protection, and an emergency / hazard unlocking function.
• Broad Compatibility
  While intended as an accessory for Aqara smart locks, this cylinder is compatible with many Euro profile lock systems, making it usable even in mixed smart/home retrofit setups.
• Easy Installation
  The modular design simplifies installation. No need for custom cutting or extra machining — adjust and mount. The package typically includes extension spacers, reinforcing rods, mounting screws, keys, and tooling for installation.
• Safety & Emergency Unlock
  The cylinder supports emergency or hazard unlocking: even if a key is inserted on one side, you can still turn the lock from the other side in emergencies.
• Aesthetic Finish
  A brushed silver finish offers a clean, modern look suited to a variety of door styles and hardware.
