Keys
Most modern vehicles require a transponder key or fob in order to operate, providing security and protection against theft. The keys are programmed by a locksmith or an authorized dealer to function with your car's system and the specific model. It is expensive to replace them if they're lost, so it's better to have spares in your possession. You can find key fobs that can be replaced in online stores and many brick-and mortar auto shops. But how can you tell that the key fob you bought is authentic? Can you tell if the unit has been programmed to work with a different vehicle, or if it can be programmed again?
If reprogram car key looking to program an entirely new key, the first step is to ensure that your car is running. Insert the key you wish to program into the ignition, but don't turn it. You only have just a few seconds before the car's system reverts the commands and exits programming mode. Therefore, it is crucial to move fast and not wait between steps. Stop the engine to prevent this. You can check the car's system by turning the key to the "on" position and back to the "off" position. The door locks should cycle, and you will hear a chime to indicate that the process was successful.
Certain newer vehicles have rolling key system, which prevents thieves from using a stolen car's key to open it. This technology is still vulnerable to a technique known as replay attacks, which allows thieves to record the signal of the vehicle's key fob and reproduce it later to unlock the car. To stop this, manufacturers added security features known as the CAN bus protocols to stop hackers from gaining access to the vehicle.
Some manufacturers also use special encryption on their key fobs which cannot be decoded by an easy program. It is best to only attempt this method if you have experience is in electronics. Consult your car's manual or look up the manufacturer's website to learn how to program it. The steps will vary according to the type of vehicle.
Transponder chips
Transponder chip car keys require a specific reprogramming to work. While any hardware store can cut a new key for you, the real issue is how to integrate it to work with the specific car you own. The key needs to be programmed to match the exact identification code on your car, or else it will not start.
Transponder chips, used to stop theft of cars, are a common feature of modern cars. The chip is a small microcircuit which transmits a radio-frequency signal when the ignition key is placed. The car then detects the signal and begins the engine in case it matches the original signal that was programmed into the vehicle. The car is also programmed to stop if it detects an invalid frequency. This makes it more difficult for novice car thefts to hot-wire a vehicle and then turn it on.
The key and the chip are connected via the circuit board which includes an induction coil. When the key is placed in the ignition it creates a magnetic field generated around the transponder. This generates a signal that is absorbed by the coil and sent to the key's identification. The ID number of the key is sent back to the vehicle, and if it matches the engine will start.
There are a variety of ways to program a key transponder, but each requires the use of a specific tool. You can purchase these tools online or at most automotive locksmiths. They're not cheap, but they're essential for programming the chip to your vehicle.

In this case, make sure that the key hasn't been damaged or the transponder has not been altered in any way. To check this, you'll need a scanner or a computer with a USB port to read the chip and determine its identity.
Reprogramming a transponder key is quite simple, however it requires an expertly designed software and scan tool. If you're new to the process it is recommended to seek the assistance of an auto locksmith. You should also avoid buying second-hand keys as they're probably already programmed and will not be compatible with your car.
