1. Use the valet key. If you have a valet key, you can use it to unlock the car and disable the anti-theft system. The valet key is usually smaller than the regular key and does not have a remote control.
2. Enter the PIN code. If you know the PIN code for your car, you can use it to disable the anti-theft system. The PIN code is a four-digit number that is programmed into the car's computer. You can find the PIN code in your car's owner's manual.
3. Use a scan tool. If you have a scan tool, you can use it to connect to the car's computer and disable the anti-theft system. Scan tools are available at most auto parts stores.
4. Bypass the anti-theft system. If you are unable to use any of the above methods, you may be able to bypass the anti-theft system by disconnecting the battery. However, this is not recommended as it may cause other problems with the car.
If you have tried all of the above methods and the car still will not start, you should take it to a qualified mechanic.
