How do you program a key?

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 of the ignition cylinder. As time passed and technology improved as it did, car manufacturers began blending electronic and physical protocols to prevent theft. These key systems are referred to as transponder keys or chip keys, and they're designed to make it more difficult for thieves to open the vehicle.

The key chips in the keys have a unique serial number, which transmits an electronic signal to the receiver inside your car keys reprogramming. The signal is compared with an identifier in the computer of the car when it is received. If the codes match, then the car will start. If the codes aren't compatible, your car won't even start. This is the reason you should keep a spare car key, especially if the system is transponder-based.

If you're looking to learn how to program keys, you'll require certain equipment. You'll need an uncut key that matches the car's model and make.

This will prevent any unauthorized attempts to start the car since only the right key will be able to do so.

The technology is believed to be more secure than the traditional car key since it makes it difficult for a thief "hot wire" the vehicle and then start it.

The key fobs have electronic chips that transmit radio signals with the car's receiver. The car's computer then compares this code on the key to the one in its database. If the codes match the car will be able to start. If the codes don't match then the car will not start or remain dead.
