Basically the title. I confirmed with management that the system for these hotel style door locks are no longer in use and they likely even moved doors from their original location in the process of remodeling the building into apartments. I’m just trying to prevent myself from getting locked out and avoid using my regular key if I can. I’ve tried reading it with an NFC reader and it didn’t work so I imagine it was to be RFID?

Any tips on where to start? I am an experienced software engineer, but I haven’t done any hacking before. I can buy tools to do the job if necessary

Edit: Added pictures for the cynics. It is my apartment
