Keys

Nearly all modern vehicles require a transponder fob or transponder keys to operate, ensuring security and anti-theft protection. The keys are programmed by a locksmith or an authorized dealer to function with your car's system and the specific model. They are expensive to replace in the event of loss, so you should have spares in your car. You can find replacement key reprogramming fobs in online stores, as well as many brick-and mortar auto shops. How can you be sure that the key you purchased is authentic? Can you tell if it has been programmed for a different vehicle or if it can be reprogrammed to fit your vehicle?

To program a new car key, you must first verify that your car is running. Insert the key you wish to reprogram into the ignition without turning it. You will only have a few seconds before the car's system resets commands and exits programming mode. It is important that you move quickly and don't wait between each step. Shut 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 process has been successful.

Certain newer vehicles utilize rolling key technology to prevent thieves from using stolen keys to start the car. This feature is still vulnerable to a technique known as replay attack that allows thieves to record the signal received from the key fob of the car and reproduce it later to open the car. To prevent this, manufacturers introduced security features known as the CAN bus protocols to stop hacking.

Some manufacturers also use special encryption on their key fobs that cannot be decoded with an ordinary program. You should only try this process if your experiences are with electronics.

Transponder chips

Transponder chip car keys require a special reprogramming to function. While any hardware store can cut a new key for you, the real problem is to make it work in conjunction with your particular car. The key you reprogrammed needs to match the specific identification number of the vehicle otherwise it won't even start the engine.

Transponder chips are a standard feature in modern cars and are designed to prevent car theft. The chip is a small microcircuit that transmits a radio-frequency signal when the ignition key is placed. The car then scans for the signal and begins the engine if it is in line with the original one that was programmed into the vehicle. The vehicle is also programmed to stop if it detects an invalid frequency. This makes it much more difficult for novice car thieves to connect a vehicle with hot wires and then start it.

The chip and the key are linked by the circuit board which includes an induction coil. When the key is placed in the ignition, it creates an electromagnetic field around the transponder. This produces a signal which gets absorbed by the coil, which then transmits it to key's identification number. The key's identification number is then sent back to the car and the engine will start when the identification number matches.
