Looking for any information on this proprietary pcb. Also any info on how a board like this board works (other than it being a receiver) would be very helpful. I'm just trying to understand it's operation so I can find the fault, seems there is a high failure rate and security issues years ago. A local hotel reached out to me and asked if I would have a look - curiosity & always wanting to learn more got the best of me. There is an issue with door able to unlock but remains that way after activation.
