Keys

Most modern cars require a transponder key to operate. This gives security and protection against theft. These keys are programmed by a locksmith or authorized dealer to function with your car's systems and specific model. It is expensive to replace them if they become lost, so it's better to have spares available. You can locate key fobs to replace them in online stores, as well as numerous brick-and-mortar auto shops. How do you ensure that the new one you have bought is genuine? Can you tell if it has been programmed to work with another 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 want to reprogramme into the ignition, but do not turn it. You have just a few minutes before the system will reset all commands and then exits the programming mode. For this reason, it is important to move fast and not be able to wait between steps. Stop the engine to prevent this. You can check the car's system by turning the key to the "on" position, then back to the "off" position. The door locks should cycle, and you'll hear a chime signalling that the process was successful.

Certain vehicles of recent years use rolling keys to stop thieves from using stolen keys to start the vehicle. This feature is still vulnerable to a method known as replay attack, which allows thieves to record the signal of the key fob of the car and then replicate it to unlock the car. To stop this, manufacturers have introduced a security feature called the CAN bus protocol to prevent attacks on hacking.

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 main issue is how to integrate it with your specific car. The key you reprogrammed needs to match the exact identification number of your car otherwise it won't even start the engine.

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

A circuit board that has an induction coil that connects the key to the chip. When the key is put in the ignition the magnetic field is created around the transponder. This creates a signal which is taken up by the coil before being sent to the key's identification. The key's identification number is then transmitted back to the car and the engine will start when the identification number matches.
