As time passed and technology advanced as it did, automobile manufacturers began blending physical and electronic protocols to prevent theft. These key systems are also referred to as transponder keys or chips keys are designed to make it difficult for thieves to start a vehicle.
The key chips inside the keys have a specific serial number that transmits an electronic signal to the receiver inside your car. The signal is compared to a code in the computer of the car when it is received. If the codes match, then your car will begin to start. If the codes don't match, then your car will not even start. This is one of the primary reasons you should keep a spare key on your vehicle, especially if you have an electronic transponder.
You'll need special equipment to be able to program keys. You'll also need to purchase the blank key for your particular model and make.

The chip absorbs this energy, and then transmits a radio frequency signal that includes an identification code. The code is matched to the unique serial numbers of the computer of the car. This prevents unauthorized attempts to start the car because only a valid key will be able to do so.
This technology is believed to be more secure than conventional car keys because it makes it much harder for a thief to "hot wire" the vehicle and get it started.
