How do you program a key?
Up until the turn of the 21st century most cars used basic key systems. The keys were made of metal and featured grooves that correspond to the internal parts of the ignition cylinder. However, as time progressed and technology advanced and improved, automobile manufacturers began blending physical and electronic protocols to protect against theft. These key systems are known as transponder keys or chip keys and they’re designed to make it more difficult for thieves to open the vehicle.
The key chips that are in the keys have a unique serial number that sends signals to the receiver in your car. When the signal is received, it compares it to the code that is stored in the car’s computer. If the codes match the car will begin to start. If the codes aren’t compatible, your car won’t even start. This is one of the primary reasons you should keep a spare key in your vehicle, particularly in the case of transponder-based systems.

Modern cars come with keyless entry systems. The system works by emitting radio signals that are detected by the keyfob. The signals are compared with the code stored in the car’s computer and, if all is in order the car will be able to unlock. The car won’t start in the event that the signals are not the same. There are several steps you can take to program your new key fob, if it’s not programmed yet.

This stops unauthorised attempts to start the car since only proper keys will be able to do so.
It is believed that this technology will be more secure than conventional car keys because it makes it more difficult for thieves to “hot wire” the vehicle and get it started.
