Your security light is on for one are two reasons. You should check your wire terminals in the connectors at your body control module which is mounted under the dash on the drivers side. You should unplug the three connectors at the body control module and inspect the terminals in the connector to see if they may be open more than they should be. You can do this by comparing all the terminals together and be sure they all look the same. If you find no problem with the terminals is the body control module connectors then the next step is to replace the ignition switch. If the terminals are good then replacing the ignition switch will fix your security problem. You installed a passlock bypass kit to bypass your passlock sensor which is located on your ignition lock cylinder. The problem is in your ignition switch. If you follow this procedure you will fix your security problem. I am glad I was able to help you today.
