How to Program a Key

Before the turn of the 21st century the majority of cars utilized basic key systems. The keys themselves were metal with grooves that corresponded to the internal parts of the ignition cylinder. However, as time progressed and technology improved as it did, automobile manufacturers began to combine physical and electronic protocols to stop theft. These key systems are known as transponder keys or chip keys, and they're designed to make it harder for thieves to start the vehicle.

The key chips contain a unique serial code that sends a message to the receiver in your car. When the signal is received it is compared to the code that is stored in the car's computer. If the codes are identical then your car will start. If not, it will not start at all. This is why it is important to keep a spare car key, especially if the system is transponder-based.

This stops any attempts by anyone else to start the car, as only proper keys will be able to do so.

The technology is believed to be more secure than traditional keys for cars because it makes it much difficult for thieves to "hot wire" a vehicle and get it started. But it's not foolproof, and thieves have discovered ways to deceive and defy the system - which means that even cars equipped that have transponder keys aren't safe from theft.
