Vehicles from the 1990s or older, which often have a carbureted engine, a manual transmission, and a single ignition coil and distributor, can be hot-wired from the engine bay. Using standard lock picking to start a vehicle is now usually ineffective, since most cars now use immobilisers or transponder key verification. Conversely, most types of motorcycles are often easier to hot-wire, especially scooters and older naked bikes, which lack advanced security features beyond mechanical locks and conventional ignition switch.
