You specifically want UWB approach unlocking and have compatible phones and Thread/Matter infrastructure.
Fingerprint, keypad, and Home Key solve the problem and an Aqara hub can cover desired remote features.
The door is not a compatible single-cylinder deadbolt or household fallback access is unclear.
The U400 earns its price when compatible household phones can use approach-based UWB unlocking and the home already has the right controller infrastructure.
The U100 is the pragmatic choice when fingerprint, keypad, Home Key, and a physical-key fallback cover daily use.
Measure the deadbolt, door thickness, backset, and clearance; confirm the exact regional version and required hubs before checkout.
Spend more when the upgrade adds a dependable entry method your household will use, while preserving key, keypad, or emergency access.
Spend less when fingerprint or keypad access solves the problem and UWB, Home Key, or advanced automation would add unused complexity.

No. It is better when UWB approach unlocking and Matter over Thread are useful in your home. The U100 covers common fingerprint, keypad, and Home Key routines for less.
It depends on the lock and feature. The U100 relies on an Aqara hub for remote and broader integrations; the U400 needs compatible Matter/Thread controller infrastructure for ecosystem features.
