Keys

The majority of modern vehicles require a transponder keys to operate. This gives security and protection against theft. These keys are programmed by a locksmith or an authorized dealer to function with your car's system and specific model. They can be costly to replace in the event of loss, so you should have spares in your car. You can purchase key fobs that can be replaced in online stores, as well as many brick-and mortar auto shops. But how can you tell that the new one you purchased is authentic? Can you tell whether it was programmed for another car or if it is able to be programmed to work with your car?

If you want to program an entirely new key the first step is to ensure that your car is running. Insert the key you want to reprogramme into your ignition, but do not turn it. There are only a couple of seconds before the car's system resets the commands and exits programming mode. For this reason, it is essential to be quick and not pause between steps. To avoid this happening, shut off the engine. Turn the key from "on" to "off" to test the system. You should hear a sound signalling that the procedure was successful. The door locks will go through a cycle.

Some newer vehicles use rolling keys to stop thieves from using stolen keys to open the car. The feature is still vulnerable to a technique called replay attack. It allows thieves to record and later duplicate the signal generated by the vehicle key fob to open the car. To stop this, manufacturers added the security feature known as the CAN bus protocols to stop hacking.

Transponder chips

Car keys that feature transponder chips need special reprogramming to work. While any hardware store can cut a new key for you, the main problem is to make it work in conjunction with your particular car. The key must be programmed to match the exact identification code on your vehicle, or else it won't start.

Transponder chips are a standard feature in modern cars and are designed to stop car theft. The chip is a microcircuit that transmits a radio frequency signals when the key is put in the ignition. The car then scans for the signal and starts the engine in case it matches the original one that was programmed into the vehicle. The car also shuts down if a frequency is invalid. This makes it much more difficult for thieves who are not experienced to hot wire a vehicle and start it.

The key and the chip are connected by the circuit board which includes an induction coil. When the key is put in the ignition the magnetic field is created around the transponder. This generates a signal that is absorbed by the coil, which transmits it to the key's identification number. The key's identification code is sent back to the car and the engine is started if the identification number matches.
