How do you program a key?

Before the turn of the 21st century, most cars used basic key systems. The keys were made of metal and incorporated grooves to match the internal components of the ignition cylinder. As technology advanced the number of car makers began to combine electronic and physical protocols to stop theft. Key systems, also known as transponder keys or chips keys are designed to make it more difficult for thieves to open the vehicle.

The key chips inside the keys have a unique serial number that sends signals to the receiver in your car. The signal is compared with a code in the car's computer when it is received. If the codes are identical then your car will begin. If not, it won't start at all. This is the reason you should keep a spare car key, especially if your system is transponder-based.

Key fobs are equipped with electronic chips that transmit radio signals with the car's receiver. The computer in the car then compares the key's code to the one in its database. If the codes match, the car will start. If not, the vehicle will not start or fail to start.
