I'm seeing a lot of people that have locks on their cars boxes or people who have had their cards stolen. I wasn't planning on putting a lock on my box and if I did, I feel like someone could just pick the lock anyway. Are you putting a lock on yours? Mine will be in a foyer just outside of the main reception area so I feel like there will be a lot of people around most of the time so it might deter people from stealing..not sure what to do.
