Editor's Pick: Featuring "keyless entry + multiple access methods," this lock integrates fingerprint recognition, password entry, IC card access, and app control, making it suitable for different family members. The fingerprint recognition is very fast—essentially unlocking with just a touch—making it much more convenient when you're carrying packages or groceries home. It supports temporary passwords and remote management, allowing you to grant temporary access to visitors or housekeepers without handing over physical keys. The auto-lock function automatically secures the door after closing, which is especially helpful for those who frequently forget to lock up. Overall installation is relatively simple.
