Question about 1994 Oldsmobile Cutlass Supreme
How do I get the code or reset it if I don't have it and the previous does not either?
Please be more specific as to whether it is a factory or aftermarket unit. Either way, please provide make and model, Not a biggie, I answer this question a lot.

The ignition lock cylinder case, including the Passlock?"¢ sensor
The ignition switch
The body control module (BCM)
The security indicator on the instrument cluster
The powertrain control module (PCM)
Body Control Module (BCM)
The body control module (BCM) contains the logic of the Theft Deterrent System. The BCM provides the battery positive voltage to operate the Pass lock" sensor. The BCM also measures the voltage of the security sensor signal circuit. The voltage measured will indicate whether the Pass lock sensor has been activated and whether the resistance value from the sensor is a valid value or the tamper value. If voltage measured is in the valid range, the BCM compares this voltage, voltage code, to a previously learned voltage code. If the voltage codes match, the BCM sends a class 2 message containing a password to the powertrain control module (PCM). If the voltage codes do not match, or the voltage is in the tamper range, or there is a circuit fault, the BCM will not send the correct password to the PCM, and the vehicle will not start.
there is nothing you can do , if your vehicle won't start you need to take it to the dealer or a ASE certified repair shop. Messing with the anti-theft system may render your vehicle useless .

If the theft light is on there is a problem and a code set. You can try to do reset . Turn the key on , don't try an start the car . Let key on for 10 min. till the light goes out, if it goes out turn ignition off an wait a couple of min. then start the car
