Cody Brocious estimates there are 4 million Onity HT locks worldwide
If, during your next hotel stay, you're met with a lock on your door like that pictured above, it's time for a conversation with management. This is an Onity HT series lock. Cody Brocious claims that the company has sold 10 million of its various locks to hoteliers, accounting for half of all locks worldwide, and appearing in one in three hotels. Described by Onity as its "flagship product," the HT series lock is its big seller: Brocious reckons there are 4 million HT series locks out there. Why does this matter? It matters because on July 24, Brocious took to the stage at the Black Hat conference in Las Vegas to demonstrate how to unlock one in a matter of milliseconds using gear you and I can buy off the shelf from Radioshack for under 50 bucks.
