Reprogramming Car Keys

Transponder keys are said to be more secure for cars and are more difficult to copy by thieves. Keys may need to be programmed again in the event of damage or lost.
You can change the programming of your key fobs at home, however you should be aware of the proper procedure. For the best results, you'll need the following items:
Keys
Modern cars require a transponder keys to operate. This is a security feature and protection against theft. These keys must be programmed to your particular car and its systems by a certified locksmith or dealer. They are expensive to replace if they are lost therefore, you should keep extras handy. You can purchase key fobs to replace them in online stores, as well as many brick-and mortar auto shops. But how do you know that the new key fob you bought is genuine? Are you able to tell whether it has been programmed for another car or if it is able to be reprogrammed for yours?
To program a new car key, you must first verify that your car is running. Insert the key you wish to program into the ignition without turning it. There are just a few minutes before the system will reset all commands and leaves the programming mode. It is crucial to move quickly and do not be patient between each step. Shut off the engine to stop this. Turn the key from "on" to "off" to test the system. There should be a chime signalling that the procedure was successful. The door locks will go through a cycle.
Certain cars with more modern technology have rolling key system, which stops thieves from using stolen cars' key to open it. This feature is still vulnerable to a technique known as replay attack, which allows thieves to record the signal received from the key fob of the car and reproduce it later to open the car. To combat this, manufacturers introduced the security feature known as the CAN bus protocols to ward off hackers from gaining access to the vehicle.
Certain manufacturers employ a specific encryption on their keys, which cannot be decoded by an ordinary program. These kinds of cars will need to be programmed by a professional, and you should only attempt this process only if you've worked with electronics. Refer to the manual for your car or go to the manufacturer's website to find out how to program it. The steps will vary according to the type of vehicle.
Transponder chips
Car keys with transponder chips require a special reprogramming to work. Any hardware store can give you a new car key, however the real challenge lies in making it work with your vehicle. A reprogrammed key will need to be matched with the exact identification number of your car otherwise it won't even start the engine.
Transponder chips, used to stop theft of cars, are a common feature of modern automobiles. The chip is a small microcircuit which transmits a radio-frequency signal when the ignition key is put in. The car is able to detect the signal, and starts the engine only if the signal matches the original one that was programmed in the vehicle. The car is also programmed so that it will stop when it detects an incorrect frequency. This makes it more difficult for thieves who aren't experienced to connect a vehicle to a hot wire and then turn it on.
A circuit board that has an induction coil that connects the key to the chip. When the key is placed in the ignition it creates a magnetic field generated around the transponder. This generates a signal, which is absorbed by the coil and then transmitted to the key's identification. The ID number of the key is sent back to the vehicle and if it matches, the engine will begin to run.
There are a variety of methods to program a key transponder, however all require an instrument that is specifically designed for. These tools are available through the internet or from many automotive locksmiths. These tools aren't cheap but are essential for programming the chip in your car.
You can also use an resettable key that was programmed for a different vehicle. In this case you'll need to make sure that the key is not damaged or that the transponder has been altered in any way. The chip can be read with a scanner, or a computer equipped with an USB connector.
