How do you program a key

Before the turn of the 21st century, the majority of cars had 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, car manufacturers began blending electronic and physical protocols to protect against theft. These key systems are called transponder key programming keys or chip keys, and are designed to make it harder for thieves to open the vehicle.

The key chips contain an unique serial number that sends a message to the receiver inside your car. When the signal is received it compares it with an existing code in the car's computer. If the codes are compatible, then your car will start. If not, it won't start at all. This is the reason you should keep an extra car key especially if your system is transponder-based.

You'll need special equipment to be able to program keys. You'll need to buy a blank key that is compatible with the model and make of your car.
