How to program the key The majority of cars had basic key systems prior to the turn of 21st century. Keys themselves were metal with grooves that corresponded to the internal components of the ignition cylinder. As technology improved, more and more automobile makers began to mix electronic and physical protocols to stop theft. These key systems are known as transponder keys or chip keys, and are designed to make it harder for thieves to start the vehicle.
