People often ask us about “chip” or transponder keys. The term transponder refers to an RFID tag similar to those used for security in stores. The tags is moulded into the plastic head of a car key. The RFID tag receives and transmits electronic codes. In cars these codes can be fixed, encrypted or rolling depending upon the make, model and year of the vehicle.
When a transponder key is turned in the ignition the vehicle sends an electric pulse to the key. This pulse is strong enough to momentarily power the transponder. The transponder responds by transmitting a digital signal back to an antenna in the car’s ignition. If the digital code sent from the key matches one stored in the car’s immobilizer the car will start. If not, the car may crank over, but will not continue to run.
All cars sold in Canada after September 2007 must be equipped with transponder keys and a factory-installed immobilizer.
