The front-door upgrade that started this category
“I have a biometric door knob on my front door and I love it.” That firsthand experience is the reason smart entry leads this page: fingerprint access for speed, a keypad for shared codes, a physical key for backup, and app control for convenient unlocking.
Important: the exact model is not named yet, so the link below compares four-way biometric models rather than pretending one specific lock was tested.
