Keys were made from metal and incorporated grooves to correspond to the internal parts in the ignition cylinder. As time passed and technology advanced as it did, automobile manufacturers began to combine physical and electronic protocols to protect against theft. These key systems are called transponder keys or chip keys and are designed to make it more difficult for thieves to get into the vehicle. The key chips come with a unique serial code that transmits a message to the receiver inside your car. The signal is then compared to the computer of the car when it is received. If the codes match, then your car will begin to start. If not, it will not start at all.

This stops unauthorised attempts to start the car since only proper keys will be able to do so. The technology is believed to be more secure than a traditional car key since it makes it difficult for a thief "hot wire" the vehicle to start it.
