An Onity website also shows Sheraton, Hyatt, Holiday Inn, Fairmont, Radisson and other well-known hotels from Paris to Perth as also having its locks. The lock scandal began as a hacker exercise.

Onity locks have a DC power port under the keycard lock, so Brocious plugged his Arduino microcontroller into that port and was able to read the 32-bit key stored in the lock’s memory location.

At the time, Onity, a division of UTC, characterized the methods used by the hacker as "unreliable" and "complex to implement," but said that it was working to develop a firmware upgrade for the ...
