To understand why a replacement key expenses more and takes longer than a traditional secret, one need to look at how automotive security has evolved.
Early vehicles used mechanical cuts. If the essential fit the ignition cylinder, the car began. Today, essentially all automobiles produced after 1995 use an immobiliser system. Inside the plastic real estate of the essential or fob is a small microchip called a transponder. When the key is inserted into the ignition or brought near to the start button, the car's engine control unit (ECU) sends out a radio signal to the transponder. If the chip responds with the correct encrypted code, the immobiliser disengages, enabling the engine to start.
