How to disconnect anti theft system without getting a new key

i just couldn't tell them that not knowing if it is their vehicle or not...all that info is public info and easy to find.

I see what your saying. Guess i should have considered the fact that i may have just helped a thief. Next time i will be more cautious. Guess i have too much faith in humanity

Well,i do to,but i don't know about folks anymore.i use to stop and help people broke down UNTIL>girl standing on the side of the road in Charlotte broke down,man stops cause hood is up and she is crying,boyfriend comes out of woods and shoots man in the head,takes all money,car,and girlfriend drives off following him in broke down car.they forgot about the DOT camera on the Interstate where they were parked? in jail the next day,got it all recorded!
