Keys
Almost all modern cars require some kind of transponder fob or transponder keys to work, which provides security and protection against theft. These keys must be programmed to the specific car and its systems by a licensed locksmith or dealer. It's costly to replace them if they're lost, so it's a good idea to have spares in your possession. You will also find replacement key fobs in various online stores and in a variety of brick-and-mortar automotive shops. How do you ensure that the new one you purchased is authentic? Do you know if the unit has been programmed to work with another vehicle or if yours can be programmed differently?
If you are planning to program a new key the first step is to ensure that your car is operating. Insert the key that you'd like to reprogramme into the ignition, but do not turn it. You have just a few minutes before the system resets all commands and exits the programming mode. This is why it is crucial to be quick and not wait between steps. Shut off the engine to avoid this. You can check the car's system by turning the key to the "on" position and back to the "off" position. There should be a chime signalling that the procedure was successful. The door locks will go through a cycle.
Certain newer vehicles utilize rolling keys to keep thieves from using stolen keys to open the car. The feature is still vulnerable to a technique called a replay attack. It allows thieves to record and then reproduce the signal received from the car key fob to unlock the car. To counter this, manufacturers have added a security feature called CAN bus protocol to thwart hacking attempts.

The key has to be programmed to match the exact identification number on your vehicle, or else it will not start.
Transponder chips are a common feature in modern cars and are designed to stop car theft. The chip is a microcircuit that emits a radio frequency signal when the ignition key is placed. The car can detect the signal and begins the engine only if it matches the original 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 that has an induction coil connects the chip to the key. When the key is placed in the ignition the magnetic field is created around the transponder. This generates a signal that is received by the coil and then transmitted to the key identification number. The key's identification number is transmitted back to the car and the engine will start if the identification number matches.
