Since you were not able to reply to the info request I sent. I cannot be as accurate and thorough as I would like. I hope what I can provide does help.
A weak or bad battery can mimic a theft system issue and prevent the car from starting. Once the battery is charged if the car will still not start and the theft light is flashing fast then you need to pull codes to see if the PATS transceiver is faulty.
