Listen to what i say
Hi i work as an installer for best buy and if you listen to what they say then all will make sense. you have what is called an imobilzer built into your key, it is a chip that is built into the key so that when you put it in the ignition it allows the vehilce to start. this way someone could not get in and stick a screw driver in the ignition and start the vehicle. now with that said to let the vehicle start there needs to be a key in the ignition, the bypass module is a unit that mounts under the dash and you put an extra key in it with a chip in it, this way it tricks your car into thinking that there is a key in the ignition. that is why you need a bypass unit, the factory alarm if you have one is dealt with with a wire off of the viper 160xv brain. hope
