Keys with Transponder Chips

Since the mid-1990s, the transponder chip has been a vital component of most automobiles. Its name is derived from "transmitter and responder". This technology was created as a response to the rising rate of car theft. The car transponder transmits an encrypted signal. When the key is inserted in the ignition and the antenna rings around, it detects the signal. If the signal matches the password, then the engine will start. This is a big deal because most thieves simply hot wire the vehicle to start it and then take off.
Transponder chips function on the same basis as microchips in computers and cell phones. car key cut do not require constant power. They emit a low frequency electromagnetic signal that can be identified by special detectors on the ignition cylinder as well as the key head.

Keys with Electronics
Modern keys come with transponders or chips that pair to the vehicle when the key is put into the ignition.
