As technology improved, more and more car makers began to combine electronic and physical protocols in order 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 an automobile.

The key chips that are in the keys have a specific serial number, which transmits a signal to the receiver inside your car. When the signal is received it compares it with a code stored in the car's computer. If the codes are identical then your car will begin to start. If not, it will not start at all. This is why it is important to keep a spare car key, especially if the system is transponder-based.

You'll require special equipment to be able to program keys. You'll also require a blank key for your particular model and make. You can purchase them from a locksmith or a car dealership, but it's essential to get the right ones. If you use a key for another model, it will not work.

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 in the car's computer system. This stops any attempts by anyone else to start the car, as only correct keys will be able.

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