Abstract
A locking system for vehicles is disclosed. After the engine is turned off, the vehicle in accordance with this invention checks whether it is in a garage with limited space. If it is, it leaves the doors unlocked. If it determines that it is not in a garage with limited space, it checks if the car key is inside the car after the driver exited the car. If it is, it sets off an alarm for the driver to retrieve the key. If the car key is not inside the car, it further checks if the key is in close proximity. When it no longer detects the key in its close proximity outside the car, it automatically locks the doors.
