hello magcitrate_41, I’m John it sounds like the vehicle went into anti-thief mode. one thing you could try is to disconnect the battery terminals both of them. Take the terminals and tap them together to completely drain and conductive energy from all the control modules. The ideal here is to reset the system completely. After reconnecting the battery put the key in the Ignition and turn to the on position. Let sit for a minute and start the vehicle.
Also you can try this link that will help you reset the PCM.
