How do you program a key?

Before the turn of the 21st century most cars used basic key systems. The keys themselves were metal and had grooves that corresponded to the internal parts of the ignition cylinder. However, as time progressed and technology improved and improved, automobile manufacturers began blending electronic and physical protocols to prevent theft. These key systems are called transponder keys or chip keys and are designed to make it more difficult for thieves to start the vehicle.

The key chips inside the keys have a unique serial number that sends an electronic signal to the receiver in your car. When the signal is received it compares it with a code stored in the car's computer. If the codes match, then your car will start. If the codes aren't compatible, your vehicle won't start at all. This is one of the main reasons you should keep a spare key in your vehicle, particularly if you have transponder-based systems.

You'll require specialized equipment to learn how to program keys. You'll also need the blank key that matches your specific make and model.

This will prevent any unauthorised attempts to start the car, because only a valid key will be able to do so.

The technology is believed to be more secure than traditional car keys because it makes it much more difficult for thieves to "hot wire" a vehicle and start it. However, it's not foolproof and thieves have discovered ways to trick and defy the system - so that even cars with transponder keys aren't safe from theft.
