As technology advanced, more and more car makers began to combine physical and electronic protocols to avoid theft. These key systems are called transponder keys or chip keys and they're designed to make it difficult for thieves to open the vehicle.

The key chips have an unique serial number which transmits a signal to the receiver inside your car. When the signal is received it is compared to a code stored in the car's computer. If the codes match, your car will begin to start. If not, it won't start at all. This is why you should keep an extra car key especially if your system is based on transponders.

You'll need special equipment to be able to program keys. You'll need to buy a blank key that is compatible with your car model and make.

The chip absorbs this energy and then transmits a radiofrequency signal which contains an identification number. The code is matched to the unique serial numbers in the computer of the car. This is to prevent any attempts by anyone else to start the car since only proper keys will be able to do so.

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