Keys themselves were metal and featured grooves that were connected to the internal components of the ignition cylinder. As time passed and technology advanced as it did, automobile manufacturers began blending physical and electronic protocols to protect against theft. Key systems, also known as transponder keys or chips keys, are designed to make it harder for thieves to steal a vehicle.

The key chips inside the keys have a unique serial number that transmits an electronic signal to the receiver in your car. The signal is compared to the car's computer when it is received. If the codes match, then the car will start. If the codes don't match, your vehicle won't start at all. This is the reason you should keep an extra car key reprogramming particularly if your system is transponder-based.

Transponder Keys

This helps prevent an unauthorized attempt to start the car, because only a valid key can do so.

This type of technology is thought to be more secure than a conventional car key because it makes it difficult for thieves to "hot wire" the vehicle and then start it.
