Comment I Had Something Similar (Score 1) 126
I had something similar happen to me. My fiance's condo, which she owned, was located in an HOA controlled building and they decided to replace all of the exterior locks with HID cards. They also instituted a policy that limited any homeowner to 2 cards. This policy was extremely inconvenient for how my fiance lived her life; it meant she could not provide a spare set of keys to a friend, for example.
I am not a lawyer, but a rudimentary Google search did not reveal whether a homeowner has a legal right to more than 2 keys to their property. I think this is really a new area and the laws have not been considered for it. It's easy to imagine any number of situations where electronic controls could limit a homeowner from accessing their property in ways physical locks do not.
In our case, we simply sold the unit when we married and left it as someone else's problem to deal with. I would guess that the HOA has changed their policy since - expanding it to include exemptions for delivery agents, real estate agents, cleaners, etc., likely to the point of uselessness.
