Yale Linus 2

The market for smart door locks is manageable, but offers a decent selection. None of the devices tested need to hide. Switchbot offers a reasonably priced entry-level product, while Yale offers a functional extension to its comprehensive in-house security system. Why the Tedee is almost twice as expensive is beyond us. Nuki offers the best overall package.

The Linus, named after the inventor of the locking cylinder, is made entirely of metal. It looks high-quality and robust, but also bulky. When you turn it, it grips hard and also sounds a little louder. WLAN is built in for remote access, and Yale supplies an NFC tag for quick opening by placing your mobile on the door.
