Schlage AD-300 stops working after random buttons pressed on keypad
I have a customer who has several Schlage AD-300 locks installed which have keypads. They have found that when someone presses a bunch of numbers on any of those locks' keypads, seemingly in random order, the lock will stop working. It cannot be unlocked with a badge, hand entry code, or even remotely from the access control system.
The lock then has to be reset, before it will start working again.
Does anyone know why this would happen? Are there admin codes out in the wild that can do this? Should there be a way to prevent this from happening. Is there a way to restore the lock remotely, without someone having to go to the lock each time to manually reset it?
The way the customer originally explained the issue, I thought it was a one-time occurrence with just two locks. After a little back-and-forth, I found out that this has been going on for years and can affect any of their AD-300 locks which have keypads.
