Up until the turn of the 21st century, most cars used basic key systems. The keys themselves were metal and had grooves that were connected to the internal parts of the ignition cylinder. As technology advanced, more and more car makers began to mix physical and electronic protocols to avoid theft. These key systems are called transponder keys or chip keys, and they're designed to make it more difficult for thieves to get into the vehicle.
The key chips contain an unique serial number that transmits a message to the receiver in your car. When the signal is received it is compared to a code stored in the car's computer. If the codes match, then your car will start. If the codes don't match, then your vehicle won't start at all. This is why it is important to keep an extra car key particularly if your system is based on transponders.
You'll need special equipment to be able to program keys. You'll also require the blank key that matches your specific model and make. You can purchase them from a locksmith or a car dealership, but it's important to get the right ones. If you try to use a key that is from another brand, it will not work.

The energy is absorbed by the chip, which then transmits the radio frequency signal, which includes an identification code that is matched up to the unique serial number in the car's computer system. This helps prevent unauthorised attempts to start the car because only a valid key can do so.
This type of technology is thought to be more secure than a traditional car key, as it makes it harder for a thief "hot wire" the vehicle and start it. It's not foolproof, and thieves have found ways to trick and defeat the system. So even cars with transponder keys aren't safe from theft.
