These key systems are also referred to as transponder keys or chips keys are designed to make it difficult for thieves to start an automobile.

The key chips inside the keys have a unique serial number that transmits a signal to the receiver in your car. When the signal is received, it compares it to a code stored in the car's computer. If the codes match, then the programmable car keys will start. If the codes aren't compatible, your car will not even start. This is why it is important to keep a spare car key, especially if your system is based on transponders.

This is to prevent unauthorized attempts to begin the car, as only right keys can be used.

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.
