I have a ignition kill in my car. I installed a viper alarm system and added on power door locks and an ignition kill. Once I arm the alarm it kills the power to the starter. So even if you were to have the key it would be useless without disarming the alarm system by remote. Hot wiring is also useless. As far as the door locks go, everything is hidden. There is no switches for them in the car. You wouldn't even know the car had door locks until I hit the unlock button on the remote. Ill tell you what had me ordering my alarm system right away... My buddy had an old lock pick set laying around so we decided to try it on my car out of curiosity. That was enough for me... Its scary how easy it is to break into and start these older cars! Next little piece of security I would like to get is a GPS tracker. That way I can go take care of business myself if someone has the balls to steal it. I don't care what the car is insured for... It's got my time, blood, sweat, tears, and memories in it. I will be taking it back no matter what cause after all it is my property...
