did you tap the white and blue wires at bcm under sterring column

if you are comfortable tearing your vehicle apart go to bulldog security.com look up your vehicle it will show you the bcm it is the 3rd picture down it has 3 plugs white, brown ,blue you can get the door locks the colors are white and blue in the blue plug but most shops use a bypass module that controls everything including your factory security it connects to the dianostic plug bottom left of your dash right above your feet this connection should be at leat 6-7 inches before plug connecting to the purple with white wire as far as tearing apart the dash comes out then panel above your feet comes out then you will see a metal protection plate has 4 nuts holding it on then it will be easy to see bcm or look for the connection to the purple with white wire let me know it might be as simply as reprogramming module

also look for small green and blue wires out of the remote start giong to a liitle black box it should be green to green which is lock and blue to blue for unlock
