How do you program the key

Before the turn of the 21st century most cars used basic key systems. Keys themselves were metal with grooves that matched the internal parts of the ignition cylinder. As time passed and technology advanced and improved, automobile manufacturers began blending electronic and physical protocols to stop theft. Key systems like these, also known as transponder keys or chips keys are designed to make it harder for thieves to start an automobile.

The key chips come with a unique serial code that transmits a message to the receiver inside your car. The signal is compared to an identifier in the computer of the car when it is received. If the codes are similar then your car will begin to start. If not, it won't start at all. This is one of the main reasons why you should always keep a spare key in your car key programmed, especially in the case of transponder-based systems.

Transponder Keys

Transponder keys, also known as chip keys, have an embedded microchip in the head of the key. When the key is inserted into the ignition lock barrel and turned to the ON position, the antenna ring sends an electromagnetic energy blast through the transponder chip. This energy is absorbed by the chip, which then transmits the radio frequency signal, which includes an identification code that corresponds up to the unique serial number of the car's computer system. This prevents an unauthorized attempt to start the car as only the correct key can start the car.

This type of technology is thought to be more secure than a traditional car key, as it makes it harder for thieves to "hot wire" the vehicle and start it.
