As long as the battery voltage is good. The PATS light flashing fast means the computer thinks your a thief from a faulty key, transceiver or module issue. Do you get the same results from both keys? If so then the keys are likely not to blame. You will need to see which PATS codes are stored to see if there is a part needing diagnosed or replaced. Then once done you will need a scan tool to reprogram both keys back to the vehicle.
