When you insert a transponder key into the ignition, it transmits an electrical signal that is picked up by a hidden antenna circling the barrel of the ignition. This antenna is programmed to read the specific frequency of the chip within the key. The car's onboard computer will then detect that the key is valid and allow fuel to flow, turn the starter or begin it.
