Aqara Smart Lock J200 is a retrofit model developed for the Japanese market. It mounts over the existing thumb-turn rather than replacing the entire mortise, so the actual lock shape and dimensions must be checked before installation.
Matter over Thread
J200 supports native Matter over Thread. A compatible Thread-enabled Matter Controller is required for the chosen ecosystem. Remote-control and sharing capabilities depend on the actual platform and controller infrastructure.
Apple Home Key and keypad
Aqara Japan states that Apple Home Key requires a keypad configuration; the lock-only J200 does not provide Home Key. Fingerprint, PIN and compatible IC/NFC card access are also keypad functions and should not be assigned to lock-only variants.
Retrofit installation
J200 is designed to mount over a compatible existing thumb-turn using the specified mounting mechanism without drilling in suitable installations. Aqara publishes an adjustment range for thumb-turn thickness of approximately 2–22 mm, but the Japanese compatibility guide should still be checked before specification.
