Hot wiring techniques refer to methods used to start a vehicle's engine without a key. This practice is often associated with car theft, where individuals bypass the ignition system to gain access to the vehicle. The process typically involves manipulating the wires connected to the ignition system, allowing the engine to start without the original key. While hot wiring is commonly depicted in movies and television, it is illegal and unethical. Modern vehicles are equipped with advanced security systems, making hot wiring increasingly difficult. Techniques that worked on older models may not be effective on newer cars, which often include electronic immobilizers and other anti-theft features.
