What does the first car keys look like?

The first car key was invented by Charles Kettering in 1910. It was a simple switch that was used to start and stop the engine. It was located on the dashboard of the car and was operated by a key that was inserted into the switch. The first car keys were not very sophisticated and were easily stolen. As cars became more secure, car keys became more sophisticated and were equipped with anti-theft devices. Today, car keys are typically equipped with a transponder chip that communicates with the car's immobilizer to prevent the car from being started without the proper key.
