Skyline Gate Lock
The lock was changed to limit the number of key holders to those that have to do business in CNF. Too many people were leaving the gate open, and the residences nearby got pissed and complained to local govt agencies about neighborhood disturbances by those using the CNF. I say tough shit for the residences, as everyone has a right to visit the CNF. But they won. It's a case of a few idiots screwing it up for everyone.
