This will ensure that there is no damage to the computer system of the vehicle and ensure that the key is working properly. How do you program a key Prior to the beginning of the 21st century most cars used basic key systems. Keys were made from metal and incorporated grooves to correspond to the internal parts in the ignition cylinder. As technology advanced the number of car makers began to combine physical and electronic protocols to stop theft. These key systems are referred to as transponder keys or chip keys and they're designed to make it harder for thieves to start the vehicle. The key chips contain an unique serial number which transmits a signal to the receiver inside your car. The signal is then compared to an identifier in the computer of the car when it is received. If the codes are compatible, then the car will start. If the codes aren't compatible, your car will not even start. This is one of the primary reasons why you should always keep a spare key on your car, especially if you have an electronic transponder. You'll require special equipment to learn how to program keys.

The energy is absorbed by the chip and sends back the radio frequency signal, which includes an identification code that matches with the unique serial number that is stored in the car's computer system. This stops any attempts by anyone else to start the car as only the correct keys will be able. The technology is believed to be more secure than a conventional car key since it makes it difficult for a criminal to "hot wire" the vehicle and start it. It's not foolproof, and thieves have discovered ways of tricking and defeating the system. So even cars equipped with transponder keys aren't protected from theft.
