1. Locate the Security Module:
- Identify the security module in your vehicle. It's usually located under the driver's side dash, behind the kick panel.
2. Disconnect the Battery:
- Before working on the electrical system, disconnect the negative battery terminal to prevent any electrical accidents.
3. Remove the Security Module:
- Remove the screws or fasteners holding the security module in place. Carefully remove the module from its housing.
4. Identify the Correct Wire:
- Locate the wire responsible for activating the security system. It's usually a small, single-wire plug on the security module.
5. Disconnect the Wire:
- Carefully unplug the wire from the security module. This will effectively disable the factory security system.
6. Test the System:
- Reconnect the battery terminal. Test the security system by locking and unlocking the car using the key fob or the key. If the alarm doesn't activate, the system is disabled.
7. Secure the Security Module:
- Reattach the security module with the screws or fasteners you removed earlier. Make sure it's secure to avoid any potential issues.
8. Reinstall the Kick Panel:
- Replace the kick panel under the driver's side dash. Make sure it's properly secured.
9. Reconnect the Battery:
- Reconnect the negative battery terminal to restore power to the vehicle.
10. Test the Car's Functionality:
- Start the car and ensure that all electrical systems are functioning normally.
Important Notes:
- Disabling the factory security system may compromise your vehicle's security. Consider installing an aftermarket security system if you choose to disable the original one.
- If you're not comfortable working with electrical components, it's always best to consult a professional automotive technician.
- Some vehicles may have different security system setups, so this guide may not apply to all variants of the 1999 Pontiac Grand Am GT.
