Keys

Nearly all modern vehicles require a transponder fob or transponder keys to work, which provides security and protection against theft. These keys must be programmed to the specific vehicle and its features by a licensed locksmith or dealer. It is expensive to replace them if they're lost, so it's best to keep extras on hand. You can purchase key fobs to replace them in online stores and many brick-and mortar auto shops. But how can you tell that the one you purchased is genuine? Can you tell whether the unit is programmed to work with another vehicle or if it could be reprogrammed?

If you are planning to program an entirely 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. There are only a few seconds left before the system resets all commands and leaves the programming mode. It is important that you be quick and don't wait between each step. Stop the engine to prevent this. Turn the key from "on" to "off" to test the system. There should be a chime to indicate that the process was successful. The door locks will cycle.

Certain vehicles of recent years use rolling keys to keep thieves from using stolen keys to start the car. This feature is still vulnerable to a technique dubbed a replay attack that allows thieves to record the signal received from the vehicle's key fob, then reproduce it to unlock the car. To prevent this, manufacturers have added a security feature called the CAN bus protocol to stop hacking attempts.

Certain manufacturers also employ special encryption on their key fobs, which cannot be decoded by an ordinary program. You should only attempt this method if you have experience is with electronic devices. Consult your car's manual or go to the website of the manufacturer to find out how to program it. The steps will vary depending on the model of vehicle.

Transponder chips

Transponder chips, used to prevent car theft are a standard feature of modern automobiles. The chip is a small microcircuit that transmits a radio-frequency signal when the ignition key is placed. The car detects the signal and starts the engine only if the signal matches the original that was programmed in the vehicle. The vehicle is also programmed to stop when it detects an incorrect frequency. This makes it much more difficult for car thieves with no experience to wire a vehicle 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 generated around the transponder. This generates a signal that gets taken up by the coil, which then transmits it to key's identification number. The key's ID number is then sent back to the vehicle and if it matches, the engine will begin to run.
