An Oak City Locksport member figured out a way to decode the 5422/23D Key Box. This new decode method was released at CackalackyCon and Layer8. Note that if *too* much pressure is used that the buttons *can* break.
Boxes like these are typically on doors for real estate agents, or mounted on buldings for facilities/maintenance teams, FCAP or telco rooms, etc. The problem is that if you can easily decode these, your high security keys or cards are now exposed.
