Lockly’s Secure Pro combines a random number generator with an app. It comes with a keypad that generates numbers in random order every time you need to enter your passcode. Each input on the keypad is actually three numbers, so even if someone watches along as you tap the code in, they likely wouldn’t be able to guess what you’ve entered. Apart from the keypad, there is also a fingerprint scanner and a way to unlock through either the mobile app or through voice assistant command. In case you can't open it with anything, there is a regular key as well.
