Aside from normal security precautions like locked, card-readable doors and optional safety deposit boxes, most hotels in Taipei do not employ special security practices. The doors to the individual rooms are locked, and there are normally small safes either in the rooms or at the cashier's desk in the lobby.
However, there are no impediments to non-guests walking the halls of the guest floors. Hotels with underground parking normally have elevators to the upper guest floors, so a person can drive into the underground parking, leave a vehicle, and access the guestrooms without passing the lobby.
