Keys

The majority of modern vehicles require a transponder keys to operate. This provides security and protection against theft.

You can purchase key fobs that can be replaced in online stores as well as many brick-and mortar auto shops. But how can you tell that the new key fob you bought is authentic? Can you tell whether the unit is programmed to work with another vehicle or if it could be programmed again?

To program a new car key, you must first verify that your vehicle is running. Insert the key you wish to reprogram into the ignition without turning it. You have just a few minutes before the system resets all commands and leaves the programming mode. This is why it is essential to move fast and not pause between steps. Turn off the engine to prevent this. Change the key from "on" to "off" to test the system. The door locks should be able to cycle, and you'll hear a chime to indicate that the procedure was successful.

Certain newer vehicles have rolling key technology that keeps thieves from using stolen cars' key to open it. This technology is still vulnerable to a technique dubbed replay attacks that allows thieves to record the signal received from the vehicle's key fob, then reproduce it to open the car. To prevent this, manufacturers have added a security feature called the CAN bus protocol to prevent hacking attempts.

These types of cars will need to be programmed by a professional, so you should only attempt this procedure if you have experience working with electronics.

Transponder chips

Car keys with transponder chips require a special reprogramming to work. While any hardware store can cut a new key for you, the real challenge is making it function to work with the specific car you own. The key must be programmed to match the exact identification number on your car, otherwise it won't be able to start.

Transponder chips, which are used to stop theft of cars are a standard feature of modern automobiles. The chip is a small microcircuit that transmits a radio-frequency signal when the ignition key is placed. The car is able to detect the signal, and starts the engine only if it matches the original that was programmed in the vehicle. The car also shuts down if the frequency is invalid. This makes it harder for thieves who aren't experienced to connect a vehicle to a hot wire and then turn it on.

The chip and the key are connected by a circuit board that includes an induction coil. When the key is placed in the ignition the magnetic field is generated around the transponder. This generates a signal, which is received by the coil and then transmitted to the key's identification number. The key's ID number is then sent back to the vehicle, and if it is in line with the engine will begin to run.
