Keys

Nearly all modern vehicles require some kind of transponder key or fob key programming in order to work, which provides security and protection against theft. The keys must be programmed to the specific vehicle and its systems by an authorized dealer or locksmith. It is expensive to replace them if they become lost, so it's best to keep extras on hand. You can also find replacement key fobs at various online stores and in many brick-and-mortar auto shops. But how do you know that the new one you have bought is genuine? Do you know whether it was programmed to work with another vehicle or if it is able to be programmed to work with your car?

You have only a few seconds before the system resets all commands and exits the programming mode. Therefore, it is essential to move quickly and not wait between steps. Stop the engine to stop this. Change the key from "on" to "off" to test the system. There should be a chime signalling that the procedure was successful. The door locks will cycle.

Some newer vehicles use rolling key technology to prevent thieves from using stolen keys to open the car. This feature is still susceptible to a technique dubbed replay attack. It allows thieves to record and reproduce the signal received from the vehicle key fob to open the car.

A key that has been reprogrammed will need to be matched with the exact identification number of the vehicle otherwise it won't even start the engine.

Transponder chips, used to stop theft of cars are a standard feature of modern automobiles. The chip is a small microcircuit that emits a radio frequency signal when the ignition key is inserted. The car detects the signal and begins the engine only if the signal matches the original one that was programmed into the vehicle. The car is also programmed so that it will stop if it detects an invalid frequency. This makes it more difficult for thieves with no experience to hot-wire a vehicle and then start it.

A circuit board that has an induction coil that connects the chip to the key. When the key is placed in the ignition it creates a magnetic field created around the transponder. This creates a signal that gets amplified by the coil which sends it to the key's identification number. The key's identification number is returned to the car and the engine will start if the identification number matches.
