As technology advanced, more and more automobile manufacturers began to combine physical and electronic protocols in order to prevent theft. Key systems, also known as transponder keys or chips keys are designed to make it difficult for thieves to start a vehicle.

The key chips in the keys have a unique serial number that sends signals to the receiver inside your car. When the signal is received it is compared to a code stored in the car's computer. If the codes match, your car will begin to start. If not, it will not start at all. This is why it is important to keep an extra car key especially if your system is based on transponders.

If you want to learn how to program keys, you'll require some specific equipment. You'll need an uncut key that matches the car's model and make. You can purchase them from the locksmith shop or at a car dealership, but it's crucial to get the right ones. If you use a key for another model, it will not function.

The chip absorbs this energy and then transmits a radiofrequency signal which contains an identification number. This code is in line with the unique digital serial numbers that are stored in the car's computers. This prevents unauthorized attempts to start the car as only the correct key will be able to perform the task.

This technology is thought to be more secure than a conventional car key, as it makes it more difficult for a criminal to "hot wire" the vehicle to start it.

If the codes do not match then the car will not start or will remain dead. The majority of these electronic keys can be programmed and replaced by an expert locksmith or auto dealer with the appropriate equipment.
