Where is the deterrent module for the Pass Key system located on a 1998 Seville? Starts and then shuts itself off. Already checked the resistance of the key pellet and ok. Next step is to check the deterrent module; however, unable to locate. Please advise. Thanks.

i think its in the radio
My mistake. I am talking about the Pass Key system deterrent module. The car starts; however, shuts off immediately.
that im not sure about
Your PK3 system is part of the the starter motor control circuit. Since your starter will spin the engine, you do not have a PASS KEY problem. Perhaps fuel pressure or fuel pump or who knows?
A clue or two might be stored in your Onboard Diagnostic system and displaying any stored trouble codes will help us help you. Here is how to display your trouble codes:

i always thought that if the car went into theft mode it would start but then shut off real fast

Pull your codes as mentioned on post #5.
The radio has nothing to do with the theft deterrent module.
If your car is a '98 Seville you cannot test the resistor as there is none, what you have is a chip (digital) embedded in the key handle (PassKeyIII).
There is a coil around the ignition cylinder that excite the chip and read the password. There is a module (reader) converting the coil analog signal to a digital signal. This signal is sent to the DIM and the DIM is the one deciding if the key is good or bad and communicating it to IPC to unlock/lock the injectors.
You can not tell anything unless you pull your codes.
