• Easy Installation & Great Compatibility: The lock easily fits over your existing door lock, requiring no complex installation or modifications. Installation is simple as long as your current cylinder has an emergency function, allowing the lock to be mounted directly over the existing cylinder. The U200 Lite is compatible with Euro profile and select Scandi cylinders.

• Expanded Functionality: The Aqara U200 Lite features a pull spring function that automatically retracts the door latch upon unlocking, allowing you to open the door without touching it. This is ideal for situations where your hands are full or when you want improved hygiene. It's especially useful for inward-opening doors or those without traditional handles, simplifying entry. And simply turn the knob approximately 30 to 60 degrees, and the lock will automatically lock or unlock.
