Keys

Most modern vehicles require a transponder key or fob in order to operate, ensuring security and protection against theft. These keys are programmed by a locksmith or authorized dealer to function with your car's systems and the specific model.

But how do you know that the key fob you bought is authentic? Do you know if the unit has been programmed to work with a different vehicle or if yours can be programmed differently?

To program a new car keys, first make sure that your car is running. Insert the key you wish to reprogram into the ignition without turning it. There are only a few seconds before the system resets all commands and leaves the programming mode. For this reason, it is crucial to be quick and not pause between steps. To prevent this from happening, shut off the engine. Turn the key from "on" to "off" to test the system. The door locks should be able to cycle, and you will hear a sound that indicates that the process was successful.

Some newer cars use a rolling key technology that keeps thieves from using stolen cars' key to open it. This feature is still susceptible to a technique known as replay attack. It allows thieves to record and duplicate the signal generated by the car key fob to unlock the car. To prevent this, manufacturers have added security features known as the CAN bus protocols to ward off hacking.

The chip is a microcircuit which transmits a radio frequency signals when the key is placed into the ignition. The car detects the signal and starts the engine only if the signal is in line with the original one that was programmed into the vehicle. The car also shuts down if a frequency is invalid. This makes it much harder for novice car thieves to wire a vehicle and start it.

A circuit board equipped with an induction coil that connects the key to the chip. When the key is put in the ignition, a magnetic field is generated around the transponder. This generates a signal, which is received by the coil before being sent to the key identification number. The ID number of the key is transmitted back to the vehicle and if it is in line with the engine will begin to run.
