How do you program a key?

Most cars had basic key systems prior to the turn of the 21st century. Keys were made of metal and had grooves to correspond with the internal parts of the ignition cylinder. As technology improved, more and more car makers began to combine physical and electronic protocols to avoid theft. These key systems are known as transponder keys or chip keys, and they're designed to make it harder for thieves to start the vehicle.

The key chips come with a unique serial code that transmits a message 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, then your car will begin to start. If the codes aren't compatible, your car won't even start. This is the reason you should keep a spare car key, particularly if your system is transponder-based.

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

Modern cars are equipped with keyless entry systems. The system works by emitting radio signals that are received by a special keyfob. The signals are compared to the code that is stored in the computer of the car and, if all is in order the car will be able to unlock. The car will not start when the signals aren't identical. There are a variety of steps you can take to program your new key fob if it's not programmed yet.

The chip absorbs this energy, and then sends a radio frequency signal that contains an identification code. The code is matched to the unique serial numbers that are stored in the computer of the car. This will prevent any an unauthorized attempt to start the car because only a valid key can perform the task.

This technology is believed to be more secure than traditional car keys because it makes it much more difficult for thieves to "hot wire" an automobile and get it started. But it's not foolproof and thieves have found ways to trick and defy the system - so that even vehicles with transponder keys are not protected from theft.
