Keys

Almost all modern cars require some kind of transponder fob or transponder keys to work, which provides security and anti-theft protection. The keys must be programmed to the specific car and its systems by an authorized dealer or locksmith. They are costly to replace in the event of loss, so you should have spares in your car. You can locate key fobs that can be replaced in online stores as well as many brick-and mortar auto shops. How can you ensure that the one you bought is genuine? Can you tell whether it was programmed for another car or if it can be reprogrammed to fit your vehicle?

To program a new car key you must first ensure that your vehicle is operating. Insert the key you wish to program into the ignition, but do not turn it. You will only have a couple of seconds before the car's system resets commands and then exits programming mode. It is important that you be quick and don't be patient between each step. Shut off the engine to stop this. You can test the car's security system by turning the key to the "on" position and then back to the "off" position. There should be a chime to indicate that the process was successful. The door locks will be able to cycle.

Some newer cars use a rolling key technology, which stops thieves from using a stolen car's key to open it. This feature is still vulnerable to a technique dubbed replay attack. It allows thieves to record and then reproduce the signal received from the car key fob to unlock the car. To stop this, manufacturers have added a security feature called CAN bus protocol to stop attacks on hacking.

Certain manufacturers have a unique encryption on their keys, which cannot be decoded by an ordinary program. You should only try this method if you have experience is with electronic devices. It is a good idea to consult your car's owner manual or search for the manufacturer online, as these steps vary by car model.

Transponder chips

Car keys with transponder chips require special reprogramming to work. While any hardware store can cut keys for you, the real challenge is making it function with your specific car. The key has to be programmed to match the exact identification code on your car, otherwise it will not start.

Transponder chips, which are used to protect cars from theft, are a common feature of modern cars. The chip is a microcircuit that transmits a radio frequency signal when the key is placed in the ignition. The car can detect the signal and starts the engine only if it matches the one programmed into the vehicle. The vehicle is also programmed to stop if it detects an invalid frequency. This makes it more difficult for thieves with no experience to connect a vehicle to a hot wire and then start it.

The key and the chip are linked by the circuit board which includes an induction coil. When the key is placed in the ignition it creates a magnetic field around the transponder. This produces a signal which is absorbed by the coil, which transmits it to the key's identification number. The key's ID number is transmitted back to the vehicle, and if it matches the engine will begin to run.
