Is the security light flashing when you try and start it? If so, let's try a hard reboot to the system by removing the negative battery cable and holding it against to positive battery terminal for 1 minute, this should discharge the capacitors and let the system relearn. If this doesn't work, it sounds like the TIPM is out but to be sure you can get a CAN scanner from Amazon for about $30.00. here is a video to show you how:

I have also included the TIPM replacement instructions which are easy because it self initializes. Check out the diagrams (below). Please let us know what happens.
