When this occurs, the induction cylinder inside the car picks up the signal and sends the radio frequency signal to the anti-theft system. If the code matches then the engine will start. If not the code is found, the engine will shut down and stop turning on. This is an additional layer of protection against theft. Despite how advanced these cars are, thieves have discovered ways to steal vehicles equipped with transponder technology. A common method is to force the ignition switch to the “on” position using an angled screwdriver. Another is hot-wiring the vehicle, and bypassing the ignition system altogether. Automobile manufacturers have responded to this by introducing advanced features, such as transponder keys fobs and key fobs, which make it more difficult for thieves break into and steal cars.

When you put the key in the ignition, the coil emits an electric field that powers up the transponder chip by inducing electrical currents in it.

Modern cars are increasingly using them since they offer more convenience and security over traditional keys made of metal. Smart keys are similar to the traditional transponder key, however they come with a chip that communicates a code with the onboard computers of the car. Whenever the key fob gets close enough to the vehicle, the car recognizes the signal and opens the doors, and/or starts the engine. The key fob can also determine if it's in the trunk or cabin and will notify you with an alert if it is. Some newer models of Toyota automobiles have advanced features that use smart keys.
