they have those brake locks... that go off of a key... you can put it on ur clutch and they couldn't start your car...

you can rewire your starter to something other than the key (what i did) to some sort of hidden button, so you would need the key and the button to start... but it will not hotwire from the ignition area

or you can just get a very very loud ass sensitive alarm that way it will wake u up, or something that.

Viper 791XV has a vibrating/beeping alert that will go off when any of the alarm sensors go off.... that's a good call there
