Is there anyway to by-pass or disable the security system ? We have tried numerous times to reset it but the light will not go off , car won't stay running
Thanks

Re: Security system Sign In

You can bypass the sensor portion only of the system but the rest of the system is incorporated right into the operating system and cannot be bypassed.
This will only work if you are getting a flashing security light when trying to start it.


Here's what you have to do

Look for the black wire and the yellow wire from the passlock sensor in the column, cut the wires and you can solder in a 2.2 K ohm resistor connecting them together and then attempt to start the car. It will stall don't turn the ignition off. Leave the ignition on for ten minutes or until the theft light goes out.Turn the key off for ten seconds then attempt to start the car. If it now runs you have been successful.If it doesn't you either made a mistake or there are other problems besides the ignition lock cylinder.

Yes, you need a dealer level scan tool to access the system and see what code has been set.
