Transponder chips have drastically decreased the likelihood of theft. When you insert a transponder key into the ignition, it will transmit a signal that is detected by a hidden antenna that is positioned around the barrel of the ignition. This antenna is programmed so that it can read the specific frequency of the chip inside the key.
