Aqara has launched a crowdfunding campaign on Kickstarter for its latest product – the Smart Lock U200. This retrofit, keyless home access solution aims to provide flexibility, convenience and security through various modern unlocking methods while retaining compatibility with traditional keys.

Various Unlocking Methods

The U200 lock offers users numerous options for securely accessing their homes:

  • Fingerprint Unlocking: Up to 20 fingerprint profiles can be stored, allowing family members to unlock the door seamlessly with the touch of a finger.
  • PIN Codes: Both one-time and recurring PIN codes can be generated for guests or service providers. This allows easy sharing of access without providing copies of physical keys.
  • Mobile App Control: The lock can be paired with the Aqara Home app to enable remote locking/unlocking and access control.
  • Voice Assistant Integration: Voice commands through Amazon Alexa or Google Assistant can be used to lock/unlock the U200.
  • NFC Cards: Special Aqara NFC cards can be tapped to unlock the door, providing keycard-style access.
  • Physical Keys: For backup or emergency access, traditional physical keys can still be used with the U200 lock.
  • HomeKit Integration: Apple HomeKit users will be able to unlock the door by tapping a compatible iPhone or Apple Watch using the upcoming HomeKey support.

Matter Support

The Smart Lock U200 is one of the first Matter-compatible locks to be launched. Matter is the new industry-standard connectivity protocol that enables smart home devices from different brands to communicate with each other seamlessly.

This means that the U200 will be able to integrate out-of-the-box with Matter-enabled smart home platforms like Alexa, Google Home, SmartThings and HomeKit when support rolls out. Users can expect an optimized and unified experience when controlling the U200 lock across various ecosystems down the road.


The U200 lock is designed to be compatible with most standard doors in Europe and North America. It can replace existing lock mechanisms by attaching directly to Euro profile cylinders (with emergency unlocking function) or deadbolts.

The necessary adapters to fit the U200 onto the cylinder and deadbolt locks are included in the package. Its retrofit nature allows for straightforward installation on the majority of existing doors without extensive modifications.

Both the lock and the wireless keypad are built to withstand extreme weather, rated to operate in temperatures from -18°C to 66°C. They also have IPX5 water resistance certification to endure rain or snow.

Safety and Encryption

Aqara states that the U200 lock has passed stringent security certifications in various countries and features military-grade AES 128-bit encryption. Its data transmission is secured through TLS protocols.

These measures prevent hacking of the lock or interception of sensitive personal data. Users can rest assured that the U200 system offers robust protection against unauthorized access.
