How to Program a Car Key

How do you program a key?

Prior to the beginning of the 21st century the majority of cars had basic key systems. Keys were made from metal and featured grooves that match the internal components of the ignition cylinder. As time went on and technology advanced as it did, automobile manufacturers began to combine electronic and physical protocols to prevent theft. These key systems are called transponder keys or chip keys, and they're designed to make it more difficult for thieves to open the vehicle.

The key chips inside the keys have a unique serial number that transmits a signal to the receiver in your car. When the signal is received it is compared to an existing code in the car's computer. If the codes match, your car will begin to start. If not, it won't start at all. This is the reason you should keep a spare car key, particularly if your system is transponder-based.

You'll need special equipment to learn how to program keys. You'll need a blank key that matches the model and make of your car. They can be purchased from an auto dealership or from a locksmith but you must make sure they're the right ones. If you use a key for another model, it won't function.

To begin the process, simply insert the new key into the ignition and switch it to the "on" position. You'll need to keep the key in this position for approximately 10 minutes and 30 seconds.

The signals are compared to the code that is stored in the car's computer and, if all is well the car will start to unlock. The car will not start if the signals are not identical. There are a variety of steps you can follow to program your new key fob if it isn't already programmed.

This energy is absorbed by the chip, which then transmits the radio frequency signal, which includes an identification code that corresponds with the unique digital serial number that is stored in the car's computer system. This will prevent any unauthorised attempts to start the car, because only a valid key will be able to perform the task.

This type of technology is thought to be more secure than a traditional car key because it makes it difficult for a criminal to "hot wire" the vehicle to start it. But it's not foolproof, and thieves have discovered ways to deceive and thwart the system which means that even cars equipped with transponder keys are not protected from theft.
