If the security light is on, the vehicle is shut down by the system. There are many things that can cause it. As a result, I recommend taking it to a dealer. They are the only ones that have the proper test equipment to check it.

Why won't the car start? The lights are not coming on automatically like they are suppose to. I changed all the sensors because the car is not receiving fire somewhere for the car to start.

What sensors have been replaced? Are you getting power to the coil? Is the security light staying on or flashing when you try to start it?
