What is a transponder key and why do they cost so much?

A transponder key has a micro-chip about the size of a grain of rice embedded into the head of the key.  When the transponder key is turned in the ignition, the antenna ring around the ignition lock sends a radio signal to the transponder.  The transponder converts the radio signal into electricity and generates a radio signal that contains its unique digital signature.  This information is captured by the antenna surrounding the ignition lock and relay to the vehicles immobilzer.   If the immobilizer recognizes the digital signature of the key, it allows the vehicle to start.  If it receives a digital signature which has not been stored in the immobilizer, or no signal at all, it does not allow the vehicle to start.

The higher cost of a transponder key is due mainly to two reasons.  Number one, the key is more expensive to produce.  Secondly, the equipment used to program the key is very expensive.  Furthermore, yearly software updates are required in order to service the newest makes and models.
