Where to buy
In need of a digital door lock that provides the highest security feature possible? You might want to look into Yale YDF40, which comes equipped with a deadbolt lock made of hardened steel to prevent physical damage or forced entry. Features-wise, you can choose to unlock the door using a password or your fingerprint via the one-touch Easy Scan technology. Even if you are a new user, there’s a voice-guided system that provides you with a step-by-step walkthrough on how to set up the door lock. The rest of the highlights include an invisible keypad that is only visible with your palm touching the screen and a built-in alarm system that will go off if someone tries to break in or causes physical damage.
