How to Program a Car Key

Up until the turn of the 21st century, the majority of cars had basic key systems. The keys were made of metal and featured grooves that correspond with the internal parts in the ignition cylinder. As technology advanced, more and more automobile makers began to combine electronic and physical protocols to stop 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 inside the keys have a unique serial number, which transmits a signal to the receiver in your car. The signal is compared to the car's computer when it is received. If the codes match, then your car will begin to start. If the codes aren't compatible, your car will not even start. This is one of the main reasons to keep a spare key for your vehicle, particularly in the case of an electronic transponder.

If you want to learn how to program a key, you'll need certain equipment. You'll need to buy a blank key that is compatible with the car's model and make.

When the time has passed, you can remove the key and see if the security light on your dashboard was gone. If not then you'll have to do it again for another time.

Transponder Keys

Transponder keys are also referred to as chip key. They have a microchip embedded inside the head of the keys.

This energy is absorbed by the chip, which then transmits an audio frequency signal that contains an identification code that corresponds up to the unique digital serial number in the car's computer system. This stops unauthorized attempts to begin the car, as only right keys can be used.

This technology is believed to be more secure than conventional car keys because it makes it difficult for thieves to "hot wire" a vehicle and start it. However, it's not foolproof and thieves have discovered ways to evade and defeat the system - which means that even cars equipped with transponder keys aren't protected from theft.
