How to Program a Car Key

As time went on and technology improved, more and more car manufacturers began blending physical and electronic protocols to prevent theft. These key systems are referred to as transponder keys or chip keys, and they're designed to make it difficult for thieves to start the vehicle.

The key chips come with an unique serial number that sends a message to the receiver in your car. When the signal is received it compares it with the code that is stored in the car's computer. If the codes match, the car will start. If not, it won't start at all. This is why it is important to keep an extra car key, especially if the system is based on transponders.

If you want to learn how to program keys, you'll require some specific equipment. You'll also require an uncut key that matches your specific make and model.

This prevents any attempts by anyone else to start the car, as only right keys can be used.

The technology is believed to be more secure than traditional keys for cars because it makes it much harder for a thief to "hot wire" an automobile and start it.
