As time passed and technology improved as it did, automobile manufacturers began blending electronic and physical protocols to stop theft. These key systems, also known as transponder keys or chips keys, are designed to make it more difficult for thieves to open a vehicle.

The key chips have an unique serial number that sends a message to the receiver in your car. When the signal is received, it compares it to the code that is stored in the car's computer. If the codes are compatible, then your car will start. If the codes don't match, then your car won't even start. This is why you should keep an extra car key, especially if your system is transponder-based.

If you want to learn how to program a key, you'll need some specific equipment. You'll also need a blank key for your particular model and make. You can purchase them from the locksmith shop or at a car dealership, but it's important to get the right ones. If you try to use a key that is from an alternative model, it will not work.

To begin the process, insert the new key into the ignition and turn it to the "on" position. It is necessary to leave the new key in this position for around 10 minutes and 30 seconds.

The majority of modern cars are equipped with the keyless entry system. To enable this feature it emits radio signals that are picked up by a specific key fob. The signals are compared to the code stored in the car's computer and, if all is well the car key programing will be able to unlock. If the signals don't match and the car does not start. If your key fob has not been already programmed, it is possible to follow a few steps to programme it.

The chip absorbs this energy, and then transmits a radiofrequency signal that includes an identification code. The code is matched to the unique digital serial numbers that are stored in the car's computers. This will prevent any unauthorized attempts to start the car, as only the correct key can do so.

This technology is believed to be more secure than conventional car keys because it makes it difficult for thieves to "hot wire" a vehicle and start it.
