Reprogramming Car Keys
Car keys with transponders are believed to make cars more secure and are more difficult for thieves to duplicate. However, keys may need to be reset when it becomes damaged or lost.
You can change the programming of your key fobs at home, however you must be aware of the correct procedure. For the best results, you'll need the following items:
Keys
Almost all modern cars require a transponder key or fob in order to operate, providing security and protection against theft. These keys must be programmed to the specific vehicle and its features by a licensed locksmith or dealer. They are expensive to replace if 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. How can you be sure that the key you purchased is genuine? Do you know whether it has been programmed for another car or if it can be programmed to work with your car?
If you want to program an entirely new key the first step is to ensure that your vehicle is operating. Insert the key you wish to reprogramme into your ignition, but do not turn it. There are only a few seconds before the car's system resets the commands and leaves programming mode. For this reason, it is crucial to move quickly and not wait between steps. To prevent this from happening, shut off the engine. Turn the key from "on" to "off" to test the system. You should hear a chime signalling that the procedure was successful. The door locks will be able to cycle.
Certain newer vehicles have rolling key technology, which stops thieves from using a stolen vehicle's key to start it. The feature is still vulnerable to a technique called a replay attack. It allows thieves to record and later reproduce the signal from the key fob of the vehicle to unlock the car. To stop this, manufacturers have added a security feature 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, that cannot be decoded with an ordinary program. These types of vehicles will need to be programmed by a professional, so you should only attempt this process with someone who has experience with electronics. Refer to the manual for your car or go to the website of the manufacturer to learn how to program it. The steps are different depending on the type of vehicle.
Transponder chips
Car keys that feature transponder chips require a special reconfiguration to work. Any hardware store can make you a new car key but the real challenge is in implementing it to your car. The key needs to be programmed to match the exact identification code on your vehicle, or else it won't start.
Transponder chips, used to protect cars from theft, 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 can detect the signal, and starts the engine only if the signal matches the original one that was programmed into the vehicle. The car is also programmed so that it will stop when it detects an incompatible frequency. This makes it difficult for thieves who aren't experienced to connect a vehicle to a hot wire and then turn it on.
A circuit board with an induction coil that connects the chip to the key. When the key is inserted into the ignition, it creates a magnetic field around the transponder. This produces a signal which is absorbed by the coil, which then transmits it to key's identification number. automotive key programming is sent back to the car, and the engine starts when the identification number is in line with.
There are a variety of ways to program a transponder, but each requires a special tool. These tools can be bought on the internet or at most auto locksmiths. They're not cheap, but they are essential for programming the chip in your car.
You can also use a reprogrammable transponder key that was previously programmed for a different vehicle. In this case, you'll need to make sure that the key is not damaged or the transponder has been altered in any way. To accomplish this, you'll need scanners or a computer with an USB port to scan the chip and determine its identity.
Reprogramming an transponder's key is simple, however it requires an expertly designed software and scan tool. If you're just beginning it is recommended to seek out the help of an auto locksmith. Also, avoid buying second-hand keys as they're probably already programmed and won't be compatible with your car.

For a long time, owners of cars who required a replacement for their key fob had no other option than to go to a dealer to get their key connected to the vehicle. This is because, in order to make modern keys work, they need to be "paired". This required expensive and complex equipment that was available only to dealers.
