how do i disconnect the security system so i can start my car

Hello, do you know if you have an add-on aftermarket alarm, or if this is a "factory equipped" system? If it's factory you can't defeat it. If it's aftermarket, disconnect it. The thing is, you'll have to have testing performed with a factory system to now why it's not starting. With aftermarket, it's an entirely useless system for the most part, so just get rid of it.
