The most reliable way to bypass an ignition switch to start a car is to install a push button start system. This system can be installed with relative ease, allowing the car to be started with the push of a button, instead of with an ignition switch. Installing a push button start system requires additional wiring, but the necessary components can be purchased online and most of the installation can be done with basic mechanical tools. Once the system is installed, it can be connected to the car's existing engine wiring and the system will be ready to use. Additionally, the push button start system should come with instructions and support from the manufacturer, allowing for easier installation and troubleshooting.
