When the signal is received it is compared to the code that is stored in the car's computer. If the codes are identical the car will begin to start. If the codes aren't compatible, your vehicle won't start at all. This is why it is important to keep a spare car key, particularly if your system is based on transponders.

The energy is absorbed by the chip and sends back a radio frequency signal with an identification code that is matched with the unique serial number of the car's computer system. This prevents unauthorized attempts to begin the car since only proper keys will be able to do so.

The technology is believed to be more secure than a traditional car key, as it makes it more difficult for a criminal to "hot wire" the vehicle and then start it.
