Reprogramming Car Keys
Transponders in car keys are believed to make vehicles safer and are less likely to be duplicated by thieves. However, a key might require reprogramming if it becomes damaged or lost.
You can reprogram key fobs yourself however, you must be aware of the correct procedure. You should have these items to ensure the best results:

Keys
Modern cars require a transponder key in order to operate. This gives security and protection against theft. These keys are programmed by a locksmith or authorized dealer to work with the car's systems and specific model. They are expensive to replace in the event of loss, so 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 do you ensure that the new one you purchased is genuine? Do you know whether it was programmed for a different vehicle or if it could be reprogrammed for yours?
To program a new car key you must first verify that your vehicle is running. Insert the key you'd like to program into the ignition, but do not turn it. There are only a couple of seconds before the car's system resets commands and exits programming mode. It is essential to be quick and don't delay between each step. Turn off the engine to prevent this. You can test the car's security system by turning the key to the "on" position, then back to the "off" position. The door locks should cycle and you'll hear a sound that indicates that the process was successful.
Some newer cars use a rolling key technology that prevents thieves from using a stolen vehicle's key to start it. The feature is still vulnerable to a technique known as a replay attack. It allows thieves to record and later duplicate the signal generated by the car key fob to open the car. To prevent this, manufacturers have introduced an additional security feature known as the CAN bus protocol to thwart attacks on hacking.
Certain manufacturers also have special encryption on their key fobs, that cannot be decoded with an easy program. These types of vehicles require programming by a professional, so you should only attempt this process if you have experience working with electronic devices. It is a good idea to read the owner's manual for your car or search for the manufacturer online, as these steps vary by vehicle type.
Transponder chips
Car keys with transponder chips require a specific reprogramming to work. While any hardware store can cut keys for you, the biggest issue is how to integrate it in conjunction with your particular car. The key needs to be programmed to match the exact identification code on your car, otherwise it won't start.
Transponder chips are a standard feature of modern automobiles and are designed to stop car theft. The chip is a microcircuit that transmits a radio frequency signal when the key is put in the ignition. The car is able to detect the signal and starts the engine only if the signal is in line with the original that was programmed into the vehicle. The vehicle is also programmed to stop when it detects an incompatible frequency. This makes it much harder for novice car thieves to hot wire a vehicle and start it.
A circuit board equipped with an induction coil that connects the key to the chip. When the key is put in the ignition, a magnetic field is created around the transponder. This creates a signal that is absorbed by the coil, which transmits it to the key's identification number. The ID number of the key is sent back to the vehicle and if it is in line with the engine will start.
There are many methods to program a key transponder, however each requires an instrument that is specifically designed for. These tools are available on the internet or at most auto locksmiths. They are not cheap, but they are crucial for programming the chip to your car.
You may also use a reprogrammable transponder key that has been previously programmed for another vehicle. In this scenario, make sure that the key isn't damaged or the transponder is not altered in any way. You can read the chip with a scanner, or a computer that has a USB connector.
Reprogramming a transponder is a simple procedure, but it requires special software. It also requires a scanner tool. If you're new to the process, it's best to seek the assistance of an auto locksmith. Also, avoid buying second-hand keys as they're probably already 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 other choice than to visit a dealer to get their key linked to their vehicle.
