Keys
The majority of modern vehicles require a transponder keys to operate. This provides security and protection against theft.

They are expensive to replace in the event of loss, so you should have spares in your car. You can purchase key fobs to replace them in online stores, as well as numerous brick-and-mortar auto shops. How do you ensure that the new key fob you bought is genuine? Can you tell whether it was programmed to work with another vehicle or if it can be reprogrammed to fit your vehicle?
If you want to program an entirely new key the first step is to ensure that your vehicle is on and running. Insert the key that you wish to reprogramme into the ignition, but do not turn it. You only have a couple of seconds before the car's system reverts the commands and leaves programming mode. Therefore, it is essential to move quickly and not pause between steps. To avoid this happening, turn off the engine. Turn the key from "on" to "off" to test the system. The door locks should be able to cycle, and you'll hear a chime signalling that the procedure was successful.
Certain newer vehicles utilize rolling keys to keep thieves from using stolen keys to start the car. The feature is still vulnerable to a technique dubbed replay attack. It allows thieves to record and then reproduce the signal from the vehicle key fob to unlock the car. To stop this, manufacturers introduced the security feature known as the CAN bus protocols to prevent hackers from gaining access to the vehicle.
Certain manufacturers also have special encryption on their key fobs which are not decoded by an easy program. It is best to only attempt this process if your experience is in electronics.

Transponder chips
Car keys that feature transponder chips require a special reconfiguration to work. While any hardware store can cut a new key for you, the main problem is to make it work with your specific car. A reprogrammed key will need to match the exact identification number of your vehicle or else it won't be able to start the engine.
Transponder chips, which are used to prevent car theft are a standard feature of modern automobiles. The chip is a microcircuit which transmits a radio-frequency signal when the ignition key is inserted. The car then detects the signal and begins the engine if it matches the original frequency that was programmed into the vehicle. The car is also programmed so that it will stop if it detects an invalid frequency. This makes it difficult for thieves with no experience to hot-wire a vehicle and then turn it on.
A circuit board equipped with an induction coil connects the key to the chip. When the key is inserted into the ignition, it creates an electromagnetic field around the transponder. This creates a signal that gets amplified by the coil which sends it to the key's identification number. The key's identification number is sent back to the car and the engine is started when the identification number matches.
There are several ways to program a key transponder, however each requires the use of a specific tool. You can purchase these tools online or at most locksmiths in the automotive industry. They are not cheap, but they're crucial for programming the chip into your vehicle.
You can also use a reprogrammable transponder key that was previously programmed for another vehicle. In this case, make sure that the key has not been damaged or the transponder isn't altered in any way. You can read the chip using a scanner, or a computer that has the USB connector.
Reprogramming the transponder is a straightforward process, but requires special software. It also requires the use of a scanner. If you're just beginning it is recommended to seek the assistance of an auto locksmith. Avoid buying used keys because they may already be programmed, and they won't work with your vehicle.
