so I built a 1998 Pontiac Sunfire into a dirt track car and now the anti theft light is on and I cannot get it off I tried to GM stuff with 30 minutes here 10 minutes or 30 minutes here nothing will work so any advice would be awesome also I was wanting to know could I put three buttons on it ignition starter button and a kill switch that's all I'd like to put on there if there is a way that I can get the VAT system off and that would be greatly appreciated

First of all I dont think you have VATS, I believe you have PassLock. VATS uses a resistor key PassLock does not. So have you been using the correct procedure for PassLock?
Passlock – coded lock cylinder
The Passlock anti-theft system requires the presence of a key in the lock cylinder to enable starting. The lock cylinder contains a stationary Hall effect sensor and a rotating magnet. When the key is turned in the lock cylinder, the magnet creates a signal on the Hall effect sensor. The cylinder then sends a coded signal to the instrument panel cluster (IPC) or body control module BCM. If the IPC/BCM receives the expected coded signal, the IPC/BCM will send a message over serial data to inform the PCM that the vehicle may be started.
To perform a relearn on a Passlock system, make sure there is a fully charged battery in the vehicle. The battery will be used for 30 minutes without the alternator available for charging. Connect a battery charger to the battery to ensure power is available while programming.
Both the IPC/BCM and PCM must be working and communicating with each other.
1. Turn ignition on.
2. Attempt to start the engine, and then release the key to the “ON” position.
3. Observe the “SECURITY” indicator light. After 10 minutes the “SECURITY” indicator light will turn off.
4. Turn ignition to the “OFF” position, and wait 10 seconds.
5. Attempt to start the engine, and then release the key to the “ON” position.
6. Observe the “SECURITY” indicator light. After 10 minutes the “SECURITY” indicator light will turn off.
7. Turn ignition to the “OFF” position, and wait 10 seconds.
8. Attempt to start the engine, and then release the key to the “ON” position.
9. Observe the “SECURITY” indicator light. After 10 minutes the “SECURITY” indicator light will turn off.
10. Turn ignition to the “OFF” position, and wait 10 seconds.
11. Vehicle has now learned the new password. Start the engine.
12. With a scan tool, clear any trouble codes.
NOTE: For most cars, one 10-minute cycle will be enough for the vehicle to learn the new password. Perform all 3 cycles if the car will not start after 1 cycle. Most trucks will require all
3 cycles for learning the password.

Why aren't you replacing the key cylinder?
