Aqara Adjustable Door Cylinder (For U200 Smart Lock)

Did you purchase the flagship Aqara U200 smart lock, only to discover your existing door cylinder isn't compatible because it lacks the dual-entry emergency function? Save yourself the headache of measuring and hunting for the correct replacement at the hardware store. The Aqara Modular Adjustable Cylinder (AL-D01D) is a genuine first-party accessory engineered to mate perfectly and securely with your new smart lock motor.

Universal, Flexible Sizing

Forget about complex door measurements. The absolute greatest advantage of this cylinder is its fully modular design. You can easily adapt it to fit thin interior doors as well as thick, heavy-duty exterior security doors. The box includes an array of interlocking segments, allowing you to stretch and snap the cylinder together like building blocks.

• Base Dimensions: Without any extensions, both the interior and exterior halves measure 35 mm.
• Massive Extension Capability: The kit includes multiple precision-machined 5 mm spacers. You can extend both the interior and exterior sides by an additional +20 mm each, allowing you to build the exact cylinder format your door requires.

Premium Build and Certified Security (EN 1303)

The core cylinder is incredibly robust and fully complies with the strict security requirements of the European EN 1303 standard for building hardware. It is forged from hardened steel and advanced anti-corrosion alloys, making it highly resilient against wear, tear, and mechanical tampering. To guarantee maximum structural rigidity and prevent the lock from snapping when extended to its maximum length, the kit includes 15 varied-length steel reinforcement bars that slide into the core assembly.

What's In The Box:

• 1× Base Modular Cylinder.
• 8× Extension spacer segments (5 mm width each).
• 15× Steel reinforcement stabilization bars in varying lengths.
• Assembly screws, hex adapter, and physical keys.
• A detailed, illustrated installation manual to guide your custom build.
