Frequently Asked Questions
What is the most secure smart lock?
The Schlage Encode Plus with ANSI Grade 1 certification, AES-128 encryption, and built-in alarm sensor is currently the most secure residential smart lock.
Can smart locks be hacked?
While no lock is unhackable, modern smart locks with S2 (Z-Wave) or AES-128 encryption are extremely difficult to breach. Physical security (Grade 1 rating) is usually more important.
