Blessed Unsaflok, Who Opened the Hotel Rooms

Patron of electronic locks, hotel keycards, and anyone who trusts the badge.

Life

In March 2024 a group of researchers, including Ian Carroll and Lennert Wouters, revealed Unsaflok: a set of weaknesses in Dormakaba's Saflok RFID locks, found in hotels the world over. Starting from a single keycard of the property, even an expired one, two cards could be forged that opened any door. The fix meant updating locks and management systems, hotel by hotel.

Prayer

O Blessed Unsaflok, who opens every room with a single card, let our locks change their key when they must. Amen.

How to celebrate

Celebrated by updating the locks and key systems and, when travelling, throwing the deadbolt anyway.

One card for every door means no door truly closed.
