Up until the turn of the 21st century the majority of cars utilized basic key systems. The keys were made of metal and featured grooves that correspond to the internal parts in the ignition cylinder. However, as time progressed and technology improved, more and more automobile manufacturers began blending physical and electronic protocols to prevent theft. These key systems are known as transponder keys or chip keys, and they're designed to make it more difficult for thieves to get into the vehicle.

The key chips have a unique serial code which transmits a signal to the receiver in your car. When the signal is received it is compared to a code stored in the car's computer. If the codes are identical, your car will begin to start. If the codes don't match, your vehicle won't start at all. This is one of the main reasons to keep a spare key for your vehicle, especially if you have a transponder-based system.

If you're looking to learn how to program keys, you'll need some special equipment. You'll need a blank key that is compatible with the car's model and make.

Modern cars come with keyless entry systems. The system works by emitting radio signals that are picked up using a special keyfob. The signals are compared to the code that is stored in the car's computer and, if all is in order, the car will unlock. If the signals do not match, the car will not start. If your key fob isn't already programmed, you may follow several steps to program it.

The chip absorbs this energy and then transmits a radio frequency signal which contains an identification number. This code matches the unique digital serial numbers in the computer of the car. This stops unauthorized attempts to begin the car as only the proper keys will be able to do so.

This technology is believed to be more secure than traditional keys for cars because it makes it harder for a thief to "hot wire" an automobile and get it started.
