Keys

Most modern vehicles require some kind of transponder key or fob to work, which provides security and protection against theft. The keys must be programmed to your specific car and its systems by a certified locksmith or dealer. It's costly to replace them if they are lost, so it's a good idea to keep extras on hand.

There are just a few minutes before the system will reset all commands and leaves the programming mode. It is crucial to move quickly and don't wait between each step. To prevent this from happening, turn off the engine. Change the key from "on" to "off" to test the system. The door locks should cycle, and you'll hear a sound that indicates that the process was successful.

Some newer cars use a rolling key technology that prevents thieves from using a stolen car's key to open it. This technology is still vulnerable to a technique known as replay attacks that allows thieves to record the signal from the vehicle's key fob and reproduce it later to open the car. To combat this, manufacturers added the security feature known as the CAN bus protocols to ward off hackers from gaining access to the vehicle.

This makes it harder for thieves with no experience to hot-wire a vehicle and then start it.

The key and the chip are connected by an electronic circuit board that contains an induction coil. When the key is inserted into the ignition it creates an electric field around the transponder. This generates a signal that is absorbed by the coil and sent to the key's identification number. The ID number of the key is sent back to the vehicle and if it matches the engine will start.
