As time went on and technology improved as it did, automobile manufacturers began blending electronic and physical protocols to protect against theft. These key systems also known as transponder keys or chips keys are designed to make it difficult for thieves to steal the vehicle.
The key chips come with an unique serial number that sends a message to the receiver inside your car. The signal is compared to an identifier in the car's computer when it is received. If the codes are similar the car will begin to start. If the codes don't match, your vehicle won't start at all. This is one of the primary reasons why you should always keep a spare key in your vehicle, especially if you have a transponder-based system.

Most modern cars come equipped with the keyless entry system. To enable this feature, the vehicle emits radio signals which are picked up by a particular key fob.

The energy is absorbed by the chip and it transmits an audio frequency signal that contains an identification code that corresponds up to the unique serial number of the car's computer system. This helps prevent unauthorized attempts to start the car, because only a valid key will be able to perform the task.
This type of technology is thought to be more secure than a traditional car key since it makes it difficult for a thief "hot wire" the vehicle and start it.
