The parking garage in my building is pass controlled and inside the parking garage there is a secured bike parking room with a pass controlled door lock requiring a fob.
your key fob is programmed to open the bike room door only if you have registered with the building management as a bike commuter.
At the moment there are only 3 keys that open that door.
I park my bike in there, I usually leave my helmet, gloves and rain gear in there.
i still lock the bike.
