Passlock II SECURITY light and truck won't start!

[SunlitComet]

does it keep running afterwards while driving? when certain requirements are met the remote starter system is supposed to disengage form the vehicle leaving the ignition switch to handle it from then on. that is happening correct/ if the light is on constantly without flashing a fault in the passlock system has been found and a DTC is present. a shop with the right scanner can extract the code for you so the problem can be diagnosed. i would say you passlock bypass for the alarm system is interfering with a passlock component. thinking specifically that perhaps it opened the sensor signal circuit from the passlock module to passlock sensor.

Glad my truck doesn't have a chip key. Good ol' 97. Do what I did on my camaro and bypass the entire system. I got pissed off one day and just completely removed the Passkey system from the car. Best mod I ever did to that car.

fizz, you do know that it is the passlock system that is installed on the tahoe right?
