Reprogramming Car Keys
Transponders in car keys are thought to keep vehicles safer and are less likely to be duplicated by thieves. However, a key may require reprogramming when it becomes damaged or lost.
You can change the programming of your key fobs at home, but you should be aware of the proper procedure. It is essential to have these items to achieve the best results:
Keys
The majority of modern vehicles require a transponder keys to operate. This gives security and anti-theft protection. The keys are programmed by a locksmith or an authorized dealer to work with the car's systems and the specific model. It's expensive to replace them if they are lost, so it's best to have spares in your possession. You can purchase key fobs that can be replaced in online stores as well as many brick-and mortar auto shops. How can car key programming ensure that the one you bought is genuine? Can you tell if the unit has been programmed to work with another vehicle or if it could be reprogrammed?
If you are planning to program a new key the first step is to ensure that your vehicle is running. Insert the key you want to program into the ignition, but do not turn it. There are only just a few seconds before the car's system reverts the commands and exits programming mode. Therefore, it is essential to be quick and not pause between steps. Stop the engine to prevent this. You can test the system of your car by turning the key to the "on" position, then back to the "off" position. The door locks should cycle, and you will hear a chime signalling that the process was successful.
Some newer cars use a rolling key technology, which stops thieves from using a stolen vehicle's key to open it. This feature is still vulnerable to a technique dubbed replay attack. It allows thieves to record and later duplicate the signal generated by the vehicle key fob to unlock the car. To prevent this, manufacturers have added a security feature called CAN bus protocol to stop attacks on hacking.
Certain manufacturers also employ special encryption on their key fobs which are not decoded by an easy program. It is best to only attempt this process if your experiences are with electronic devices. It is a good idea to refer to your car's owner manual or look up the manufacturer online, as the steps will differ depending on the vehicle type.
Transponder chips
Transponder chip car keys require a specific reprogramming to function. Any hardware store can make you an entirely new car key, but the real challenge is in implementing it to your vehicle. The key needs to be programmed to match the exact identification number on your vehicle, or else it will not start.
Transponder chips, used to prevent car theft, are a common feature of modern automobiles. The chip is a small microcircuit that transmits a radio-frequency signal when the ignition key is placed. The car detects the signal and begins the engine only if it matches the original one that was programmed into the vehicle. The car will also shut down if the frequency is invalid. This makes it harder for thieves who aren't experienced to hot-wire a vehicle and then start it.
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 around the transponder. This creates a signal that gets taken up by the coil, which then transmits it to key's identification number. The key's ID number is transmitted back to the vehicle, and if it is in line with the engine will begin to run.
There are a variety of ways to program a transponder, but all require the use of a specific tool. You can purchase these tools on the internet or at many automotive locksmiths. They're not cheap, but they're vital for programming the chip in your car.
You can also use an resettable key that was programmed for an alternative vehicle. In this scenario you'll need to make sure that the key isn't damaged or that the transponder has been altered in any way. The chip can be read with a scanner, or a computer that has a USB connector.
The process of reprogramming an transponder's key is simple, but it requires an expertly designed software and scan tool. If you're a beginner it is recommended to seek help from an auto locksmith. Avoid buying used keys because they may already be programmed and will not work with your car.
EZ Installer
For a long time, car owners who required a replacement for their key fob had no choice than to visit a dealership to have their key linked to their vehicle. It is because to make modern keys function they must be "paired". This required expensive and complicated equipment that was only available to dealers.

Tools
