Keys

Most modern vehicles require some kind of transponder key or fob in order to work, which provides security and anti-theft protection. The keys must be programmed to your specific car and its systems by a licensed dealer or locksmith. It's costly to replace them if they're lost, so it's better to have spares available. You can also find replacement keys fobs on various websites and in a variety of brick-and-mortar automotive shops. But how do you know that the new one you have bought is genuine? Can you tell whether the unit is programmed to work with another vehicle or if yours can be reprogrammed?

If you are planning to program an entirely new key first, you need to ensure that your car is operating. Insert the key you wish to reprogram into the ignition without turning it. You have just a few minutes before the system resets all commands and exits the programming mode. It is important that you move quickly and do not be patient between each step. To prevent this from happening, turn off the engine. You can test the car's system by turning the key to the "on" position and back to the "off" position. The door locks should be able to cycle, and you will hear a sound that indicates that the process was successful.

Certain newer vehicles have rolling key technology that keeps thieves from using a stolen vehicle's key to open it. This feature is still vulnerable to a technique known as a replay attack that allows thieves to record the signal from the key fob on the vehicle and then replicate it to open the car. To counter this, manufacturers have introduced a security feature called CAN bus protocol to stop hacking attempts.

A key that has been reprogrammed will need to match the exact identification number of your car otherwise it won't even start the engine.

Transponder chips, used to prevent car theft, are a common feature of modern automobiles. The chip is a small microcircuit that emits 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 one that was programmed into the vehicle. The car also shuts down if the frequency is invalid. This makes it more difficult for thieves with no experience to hot-wire a vehicle and then turn it on.

A circuit board with an induction coil that connects the chip to the key. When the key is inserted into the ignition it creates an electromagnetic field around the transponder. This creates a signal that is taken up by the coil, which then transmits it to key's identification number. The key's identification number is returned to the car, and the engine starts if the identification number matches.
