Starts via SmartKey, starts & runs, but when door is opened, car shuts down/off.

Is this by design, or "feature"?


I've searched here and there, and it seems that this is the "way" it is.

Are all remote starters designed the same way so that once started remotely, they shut down when the car door is opened?

IS there a way to circumvent it, or reason why I wouldn't want to? (theft?)

Is this 'process' described in the owners manual?
