How do I disable the security system? It won't let my car start. When I put key in ignition the security light just flashes & stop gas from getting to engine. I've reset which mode the system is in but it's still doing it. I've changed it from locked mode to passive mode & to unlocked mode but the security light continues to flash. What can I do to disable it?

It sounds like you need to do a hard system reboot. Remove the negative battery cable and touch it to the positive cable for 5 minutes. This will discharge any memory capacitors. Reconnect the battery.

This guide can help as well.
