Keys

Nearly all modern vehicles require some kind of transponder key or fob to operate, ensuring security and anti-theft protection. The keys must be programmed to your particular vehicle and its systems by an authorized dealer or locksmith. They can be costly to replace if they are lost, so it is recommended to keep spare keys in the car. You can find key fobs that can be replaced in online stores, as well as many brick-and mortar auto shops. How can you know that the one you bought is authentic? Can you tell whether it has been programmed for another car or if it can be reprogrammed for yours?

If you want to program a new key first, you need to ensure that your vehicle is running. Insert the key you want to program into the ignition, but do not turn it. You have only a few seconds before the system resets all commands and exits the programming mode. Therefore, it is important to move fast and not pause between steps. Shut off the engine to prevent this. Turn the key from "on" to "off" to test the system. There should be a chime indicating that the process was successful. The door locks will go through a cycle.

Certain cars with more modern technology have rolling key technology that keeps thieves from using stolen cars' key to open it. The feature is still vulnerable to a technique known as a replay attack. It allows thieves to record and then duplicate the signal generated by the car key fob to open the car. To prevent this, manufacturers have added an additional security feature known as the CAN bus protocol to prevent attacks on hacking.

Some manufacturers use a special encryption on their keys, which cannot be decoded by a simple program. You should only try this method if your previous experiences are with electronics. It is a good idea to refer to the owner's manual of your vehicle or look up the manufacturer online, as these steps vary by car model.

Transponder chips

Transponder chip car keys require a special reprogramming to function. Any hardware store can give you an entirely new car key, but the real challenge is in implementing it to your vehicle. The key needs to be programmed to match the exact identification code on your car, otherwise it will not start.

Transponder chips are a standard feature in modern cars and are designed to stop car theft. The chip is a microcircuit that transmits a radio frequency signal when the key is placed into the ignition. The car detects the signal, and starts the engine only if the signal matches the original one that was programmed into the vehicle. The vehicle is also programmed to shut down when it detects an incompatible frequency. This makes it difficult for thieves with no experience to hot-wire a vehicle and then turn it on.

A circuit board equipped with an induction coil that connects the key to the chip. When the key is put in the ignition it creates a magnetic field created around the transponder. This creates a signal which is received by the coil before being sent to the key's identification number. The ID number of the key is then sent back to the vehicle and if it matches the engine will begin to run.

In this instance, you must make sure that the key has not been damaged or the transponder has not been altered in any way. You can read the chip by using a scanner or a computer with a USB connector.
