Before the turn of the 21st century, most cars used basic key systems. Keys were made of metal and featured grooves that match the internal components in the ignition cylinder. As time went on and technology improved as it did, car manufacturers began blending physical and electronic protocols to prevent theft. These key systems, also known as transponder keys or chips keys are designed to make it harder for thieves to open an automobile.
The key chips contain a unique serial code that transmits a message to the receiver inside your car. When the signal is received it is compared to an existing code in the car's computer. If the codes match, your car will start. If the codes don't match, your vehicle won't start at all. This is one of the primary reasons to keep a spare key in your vehicle, especially in the case of a transponder-based system.

The energy is absorbed by the chip, which then transmits a radio frequency signal with an identification code that matches up to the unique serial number of the car's computer system. This prevents unauthorised attempts to start the car as only the right keys can be used.
This type of technology is thought to be more secure than the traditional car key, as it makes it difficult for a criminal to "hot wire" the vehicle and then start it.
