Steering lock

Modern vehicles are fitted with a steering lock which is an anti-theft device. It is fitted to the steering column usually below the steering wheel. The lock is combined with the ignition switch and engaged and disengaged either by a mechanical ignition key or electronically from the vehicles electronic control unit. These locks were introduced on General Motor products in 1969 and on Ford, Chrysler, and AMC products in 1970.

In the United States, steering columns are governed by several federal regulatory requirements, notably FMVSS 108, 114 and 208.
