As time passed and technology advanced as it did, automobile manufacturers began to combine electronic and physical protocols to prevent theft. These key systems are called transponder keys or chip keys, and they're designed to make it harder for thieves to start the vehicle.

The key chips contain an unique serial number that sends a message to the receiver inside your car. When the signal is received it is compared to the code that is stored in the car's computer. If the codes are similar then your car will begin. If not, it won't start at all.

The energy is absorbed by the chip and it 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 prevents unauthorised attempts to start the car key cutting and programming, as only the correct key can do so.

The technology is believed to be more secure than the traditional car key, as it makes it harder for a criminal to "hot wire" the vehicle to start it. It's not foolproof and thieves have found ways of tricking and defeating the system. So even cars with transponder keys aren't safe from theft.
