Product notes
MatterCatalog lists as certified lock pick with fingerprint/Home Key options. Not independently page-fetched this pass beyond catalog.
Merged the duplicate CSA import record `aqara-aqara-smart-lock-u400` (+1 source).
How it differs from the type answer
- Same class of deltas as U200: biometrics/Home Key beyond type matrix.
- Confirm exact Matter version and platform matrix on Aqara product page before High confidence.
