I had a gentlemen call me to inquire about a remote start for his olds. I told him that there was a way to get around the anti theft without an actual bypass module. He said he'd get back to me. When he called me back- i dunno who he called but he was told that since he had a resistor in the key, (on the shank)- that his anti theft was "unarmed" by that resistor pushing something apart within the tumbler. Is this true?

I've done quite a few remote starts on newer vehicles, but I have not come across the actual chip in the key shank yet, so I'm seeking some advice. I've read about finding the resistor value, and soldering in a new resistor inline. With that being said, how similar to the passlock is this system? In other words, with the OEM key close to the ignition, and if the car was started with a blank......would it start?

Thanks all!!
