As time passed and technology improved, more and more automobile manufacturers began to combine electronic and physical protocols to protect against theft. These key systems are called transponder keys or chip keys and they're designed to make it difficult for thieves to start the vehicle.

The key chips that are in the keys have a unique serial number, which transmits a signal to the receiver inside of your car key programming. When the signal is received it is compared to the code that is stored in the car's computer. If the codes are compatible, then your car will begin to start. If the codes don't match, your car won't even start. This is why it is important to keep an extra car key, particularly if your system is based on transponders.

The energy is absorbed by the chip and it transmits a radio frequency signal with an identification code that corresponds up to the unique serial number in the car's computer system. This helps prevent unauthorised attempts to start the car since only the right key will be able to start the car.

This technology is thought to be more secure than a traditional car key since it makes it harder for a thief "hot wire" the vehicle to start it. But it's not foolproof, and thieves have found ways to trick and thwart the system so that even vehicles with transponder keys are not safe from theft.
