Keys

Almost all modern cars require a transponder key or fob to operate, providing security and anti-theft protection. The keys are programmed by a locksmith or an authorized dealer to work with your car's system and the specific model. They are costly to replace in the event of loss and you should have spares in your car. You can purchase replacement key fobs in online stores as well as many brick-and mortar auto shops. How can you be sure that the one you bought is authentic? Do you know if it has been programmed for a different vehicle or if it is able to be reprogrammed to fit your vehicle?

If you are planning to program an entirely new key first, you need to ensure that your car is operating. Insert the key that you wish to reprogramme into your ignition, but don't turn it. You have only a few seconds before the system will reset all commands and exits the programming a car key mode. It is important that you move quickly and don't be patient between each step.

Certain newer vehicles utilize rolling keys to keep thieves from using stolen keys to start the car. This feature is still vulnerable to a technique dubbed replay attacks which allows thieves to record the signal of the key fob on the vehicle and reproduce it later to unlock the car.

Transponder chips

Car keys that feature transponder chips require a special reprogramming to work. Any hardware store can give you a new car key, but the real challenge is in making it work with your car. The key you reprogrammed needs to be matched with the exact identification number of your vehicle, or it won't start the engine.

Transponder chips are a common feature in modern cars and are designed to stop car theft. The chip is a small microcircuit which transmits a radio-frequency signal when the ignition key is put in. The car then detects the signal and starts the engine if it is in line with the original signal that was programmed into the vehicle. The car is also programmed to shut down when it detects an incompatible frequency. This makes it much harder for car thieves with no experience to wire a vehicle and then start it.

A circuit board that has an induction coil connects the chip to the key. When the key is inserted into the ignition it creates an electric field around the transponder. This creates a signal which is taken up by the coil and sent to the key's identification. The key's identification number is transmitted back to the car and the engine is started if the identification number matches.

To accomplish this, you can use scanners or a computer equipped with a USB port to read the chip and determine its identity.
