Keys

Modern cars require a transponder keys to operate. This is a security feature and protection against theft. These keys must be programmed to your particular car and its systems by a licensed dealer or locksmith. It is expensive to replace them if they become lost, so it's a good idea to have spares in your possession. You can locate key fobs that can be replaced in online stores and many brick-and mortar auto shops. But how can you tell that the new one you have bought is authentic? Do you know if the unit has been programmed to work with a different vehicle, or if it can be reprogrammed?

If you want to program a new key first, you need to ensure that your car is running. Insert the key you want to program into the ignition, but do not turn it. There are only a few seconds before the system will reset all commands and then exits the programming mode. For this reason, it is crucial to be quick and not be able to wait between steps. Turn off the engine to prevent this. You can check the car's security 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 has been successful.

Certain cars with more modern technology have rolling key technology that keeps thieves from using stolen cars' key to start it. This feature is still vulnerable to a technique known as replay attacks, which allows thieves to record the signal of the key fob key programmer of the car, then reproduce it to open the car. To prevent this, manufacturers introduced a security feature known as the CAN bus protocols to stop hackers from gaining access to the vehicle.

Transponder chips

Transponder chip car keys require special reprogramming in order to function.

The key needs to be programmed to match the exact identification number on your vehicle, or else it won't start.

Transponder chips, used to protect cars from theft are a standard feature of modern cars. The chip is a microcircuit that transmits a radio-frequency signal when the ignition key is inserted. The car then detects the signal and begins the engine if it matches the original frequency that was programmed into the vehicle. The vehicle is also programmed to shut down if it detects an invalid frequency. This makes it more difficult for thieves with no experience to hot-wire a vehicle and then turn it on.

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

There are several ways to program a transponder, but all of them require the use of a specific tool. You can buy these tools online or at most locksmiths for cars. They are not cheap, but they're vital for programming the chip into your car.
