Most cars had basic key systems up until the turn of the 21st century. The keys themselves were metal and featured grooves that matched the internal components of the ignition cylinder. As technology improved, more and more car makers began to mix electronic and physical protocols in order to prevent theft. These key systems, also known as transponder keys or chips keys, are designed to make it more difficult for thieves to start the vehicle.

The key chips have an unique serial number that sends a message to the receiver in your car. The signal is then compared to a code in the computer of the car when it is received. If the codes match, your car will start. If the codes don't match, your car will not even start. This is one of the primary reasons you should keep a spare key for your vehicle, particularly when you use an electronic transponder.

You'll need special equipment to be able to program keys. You'll need to buy a blank key that matches the car's model and make.

The newest models also allow remote management and configuration and are cloud-based.

Modern automobiles are equipped with keyless entry systems. The system works by sending radio signals which are picked up using an specialized keyfob. The signals are compared to the code stored in the computer of the car key programming and if everything is in order the car will be able to unlock.

The energy is absorbed by the chip and it transmits the radio frequency signal, which includes an identification code that matches with the unique digital serial number that is stored in the car's computer system. This prevents unauthorised attempts to start the car, as only correct keys will be able.

This technology is believed to be more secure than conventional car keys because it makes it much harder for a thief to "hot wire" the vehicle and start it.
