Not sure who told you to cut any wires but it isn't true. That system uses a version of PassKey with a coil that sends out a signal that in turn reads the transponder in the key which is used in the Powertrain Control Module and the Body Control Module to enable the fuel system and allows the engine to run. Without the proper activation that the keys internal code causes the system to generate, the system will remain armed and the car will not run. Cutting the signal wire or any other of the wires from the switch will only make the system lock out everything including the proper keys. There are modules sold the purport to bypass the system to allow things like remote starters to operate but most are more expensive than having the keys made and they generally fail after a short time. (One of the few "good" modules sold runs about $250.00)
The best solution to this issue would be to use the VIN number to get a new key cut to match the ignition cylinder. From that key you can have other keys cut, then either use a key programmer or the GM 30 minute relearn method to make the new keys work in the system.
When performing the 30-minute relearn procedure, all previously learned keys will be erased from the TDM memory. Additional keys may be learned after performing the relearn procedure.
1. With a master vehicle key, turn ON the ignition, with the engine OFF.
2. Observe the security indicator. After approximately 10 minutes, the telltale will turn OFF.
3. Turn OFF the ignition, and wait 5 seconds.
4. Repeat steps 1-3 two more times for a total of 3 cycles or 30 minutes.
After this step you need to turn the key to OFF, then use the key to start the engine.
The vehicle learns the key transponder information and/or passwords on the ignition switch transition from OFF to RUN.
5. With a master vehicle key, start the vehicle. The vehicle has now learned the key transponder information and/or the ECM has now learned the fuel continue password.
After you have a single working key you can add additional keys (up to 10) using the following method
1. With a previously learned master key, turn ON the ignition, with the engine OFF.
2. Turn OFF the ignition and remove the key.
3. Within 10 seconds insert the new key to be learned. Turn ON the ignition with the engine
OFF. The vehicle has now learned the new key.
