Reprogramming Car Keys
Transponders in car keys are believed to make cars more secure and are less likely to be duplicated by thieves. The key could need to be programmed again in the event of damage or lost.
You can change the programming of your key fobs at home, but you need to know the right process. For the best results you'll need the following items:
Keys
The majority of modern vehicles require a transponder key in order to operate. This gives security and protection against theft. car key programming must be programmed to your particular vehicle and its systems by an authorized dealer or locksmith. They can be costly to replace if lost therefore, you should have spares in your car. You can also find replacement key fobs on various websites and in many brick-and mortar auto shops. But how can you tell that the new one you purchased is authentic? Do you know whether the unit has been programmed to work with a different vehicle, or if it can be programmed again?
If you want to program an entirely new key first, you need to ensure that your car is on and running. Insert the key that you want to reprogramme into your ignition, but don't turn it. There are only a few seconds before the car's system resets commands and leaves programming mode. It is crucial to be quick and don't be patient between each step. Turn off the engine to prevent this. Turn the key from "on" to "off" to test the system. The door locks should cycle, and you will hear a chime signalling that the procedure was successful.
Some newer vehicles use rolling key technology to prevent thieves from using stolen keys to start the vehicle. The feature is still vulnerable to a technique called replay attack. It allows thieves to record and later reproduce the signal from the vehicle key fob to open the car. To combat this, manufacturers have added the security feature known as the CAN bus protocols to ward off hacking.
Some manufacturers also use special encryption on their key fobs which are not decoded by an easy program. You should only attempt this method if your previous experience is with electronics. It is a good idea to refer to the owner's manual for your car or look up the manufacturer online, as the steps differ based on vehicle model.
Transponder chips
Car keys with transponder chips require a special reprogramming to function. While any hardware store can cut keys for you, the biggest problem is to make it work to work with the specific car you own. The key must be programmed to match the exact identification code on your vehicle, or else it won't be able to start.
Transponder chips are a typical feature in modern cars and are designed to prevent car theft. The chip is a small microcircuit that transmits a radio-frequency signal when the ignition key is inserted. The car is able to detect the signal, and starts the engine only if it matches the original that was programmed into the vehicle. The vehicle is also programmed to shut down when it detects an incompatible frequency. This makes it more difficult for thieves who are not experienced to wire a vehicle and start it.
The chip and the key are linked by the circuit board which includes an induction coil. When the key is placed in the ignition, it creates an electric field around the transponder. This creates a signal that is absorbed by the coil, which then transmits it to key's identification number. The key's identification number is sent back to the car and the engine will start when the identification number is in line with.

To do this, you can use scanners or a computer equipped with a USB port to identify the chip and establish its identity.
