As time went on and technology improved, more and more automobile manufacturers began to combine physical and electronic protocols to protect against theft. These key systems are referred to as transponder keys or chip keys, and are designed to make it harder for thieves to start the vehicle.
The key chips that are in the keys have a specific serial number that transmits a signal to the receiver in your car. The signal is then compared to the car's computer when it is received. If the codes are compatible, then your car will start. If the codes don't match, your vehicle won't start at all.

The chip absorbs this energy, and then transmits a radio frequency signal that contains an identification code. This code matches the unique digital serial numbers of the car's computers. This prevents any attempts by anyone else to start the car as only the right keys can be used.
This 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 then 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 immune to theft.
