2. Attempt to start the engine, then release the key to ON, vehicle will not start.
3. Observe the SECURITY telltale light, after approximately 10 minutes the telltale will turn OFF.

That is the reset & programming........

You have either broken a wire, disconnected something or caused a short to the BCM

You will need use of Dealer Scan Tool to test the PassLock Circuit & Modules, as there is no way for anyone to tell what has been done to the System without testing DATA via Dealer Scan Tool
