Keys
Nearly all modern vehicles require some kind of transponder key or fob to work, which provides security and anti-theft protection. These keys must be programmed to the specific vehicle and its systems by a licensed dealer or locksmith. It is expensive to replace them if they're lost, so it's better to keep extras on hand. You will also find replacement key fobs on various websites and in many brick-and-mortar auto shops. How can you be sure that the one you purchased is authentic? Do you know whether the unit has been programmed to work with another vehicle or if yours can be programmed again?
If you're looking to program an entirely new key the first step is to make sure that your car is on and running. Insert the key you want to reprogramme into the ignition, but do not turn it. There are only a few seconds before the system resets all commands and then exits the programming mode. It is important that you move quickly and do not be patient between each step. To avoid this happening, shut off the engine. Change the key from "on" to "off" to test the system. There should be a chime to indicate that the process was successful. The door locks will cycle.
Certain newer vehicles utilize rolling key technology to prevent thieves from using stolen keys to open the vehicle. This feature is still susceptible to a technique known as a replay attack. It allows thieves to record and duplicate the signal generated by the key fob of the vehicle to open the car.

Some manufacturers use a special encryption on their keys that can't be decoded with a simple program. You should only attempt this method if you have experience is with electronics. Refer to the manual for your car or look up the website of the manufacturer for information on how to program it. The steps are different depending on the type of vehicle.
Transponder chips

The key you reprogrammed needs to match the specific identification number of your vehicle, or it won't start the engine.
Transponder chips, which are used to prevent car theft, are a common feature of modern cars. The chip is a microcircuit which emits a radio frequency signal when the key is put into the ignition. The car is able to detect 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 is also programmed to shut down if it detects an invalid frequency. This makes it much more difficult for car thieves with no experience to wire a vehicle and start it.
The chip and the key are connected via the circuit board which includes an induction coil. When the key is inserted into the ignition, it creates an electromagnetic field around the transponder. This generates a signal that is absorbed by the coil and sent to the key's identification number. The key's identification code is transmitted back to the car and the engine will start when the identification number is in line with.
There are many ways to program a key transponder, but all require an instrument that is specifically designed for. You can buy these tools on the internet or at many locksmiths for cars. They are not cheap, but they're crucial for programming the chip to your car.
You can also use a reprogrammable transponder key that was previously programmed for a different vehicle. In this case, make sure that the key hasn't been damaged or that the transponder isn't altered in any way. You can read the chip by using a scanner or a computer with the USB connector.
Reprogramming a transponder is a simple procedure, but it requires specific software. It also requires an scanner tool. It is recommended to contact an auto locksmith for help in case you're not an expert. Avoid buying used keys as they may already be programmed, and they won't work with your car.
