The keys were made of metal and incorporated grooves to correspond to the internal parts in the ignition cylinder. However, as time progressed and technology improved, more and more automobile manufacturers began to combine electronic and physical protocols to prevent theft. These key systems are referred to as transponder keys or chip keys and are designed to make it more difficult for thieves to get into the vehicle.

The key chips have an unique serial number that sends a message to the receiver inside your car. When the signal is received, it compares it to an existing code in the car key programmer's computer. If the codes match the car will begin to begin to start. If the codes don't match, your car won't even start. This is one of the primary reasons to keep a spare key in your vehicle, particularly if you have transponder-based systems.

Most modern cars come equipped with an entry system that is keyless. The system works by emitting radio signals which are picked up using a special keyfob. The signals are then compared to the code that is stored in the car's computer and, if all is in order the car will be able to unlock. If the signals don't match, the car will not start. There are a variety of steps you can take to program your new key fob, if it's not programmed yet.

This energy is absorbed by the chip and sends back a radio frequency signal with an identification code that is matched up to the unique digital serial number that is stored in the car's computer system. This stops unauthorized attempts to begin the car since only right keys can be used.

It is believed that this technology will be more secure than traditional keys for cars because it makes it more difficult for thieves to "hot wire" the vehicle and get it started. But it's not foolproof and thieves have found ways to trick and defy the system - which means that even cars equipped that have transponder keys aren't protected from theft.
