Reprogramming Car Keys
Transponders in car keys are thought to keep vehicles more secure and more difficult for thieves to duplicate. However, a key may need to be reprogrammed when it becomes damaged or lost.
You can program key fobs yourself but you must be aware of the correct process. It is essential to have these items to get the most effective results:
Keys
Almost all modern cars require some kind of transponder key or fob in order to operate, providing security and protection against theft. These keys must be programmed to your particular car and its systems by a certified locksmith or dealer. They are costly to replace in the event of loss and it is recommended to keep spare keys in the car. You can also find replacement keys fobs at various online stores and in many brick-and mortar auto shops. How can you be sure that the key you purchased is authentic? Can you tell if the unit has been programmed to work with another vehicle or if yours can be reprogrammed?
If you're looking to program a new key the first step is to ensure that your vehicle is on and running. Insert the key that you wish to reprogramme into the ignition, but do not turn it. You have only a few seconds before the system will reset all commands and leaves the programming mode. It is important that you move quickly and do not be patient between each step. Turn off the engine to prevent this. You can check the system of your car by turning the key to the "on" position and back to the "off" position. There should be a chime to indicate that the process was successful. The door locks will cycle.
Certain cars with more modern technology have rolling key technology, which stops thieves from using a stolen car's key to start it. The feature is still vulnerable to a technique dubbed replay attack. It allows thieves to record and duplicate the signal generated by the vehicle key fob to open the car. To counter this, manufacturers have introduced an additional security feature known as the CAN bus protocol to prevent hacking attempts.
Certain manufacturers also employ special encryption on their key fobs which cannot be decoded by an ordinary program. These kinds of cars require programming by a professional, and you should only try this with someone who has experience with electronic devices. 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 depending on the type of vehicle.
Transponder chips
Car keys with transponder chips require special reprogramming to work. Any hardware store can offer you a new car key, however the real challenge lies in making it work with your vehicle. The key must be programmed to match the exact identification number of your car, otherwise it won't start.
Transponder chips are a typical feature of modern automobiles and are designed to stop car theft. The chip is a small microcircuit that 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 is in line with the one programmed into the vehicle. The car also shuts down if the frequency is not valid. This makes it harder for thieves with no experience to connect a vehicle to a hot wire and then turn it on.
The key and the chip are connected via the circuit board which includes an induction coil. When the key is placed in the ignition the magnetic field is generated around the transponder. This generates a signal that is taken up by the coil and then transmitted to the key's identification. The key's ID number is then sent back to the vehicle and if it matches the engine will begin to run.
There are many methods to program a key transponder, but each requires an instrument that is specifically designed for. These tools can be purchased on the internet or at most auto locksmiths. These tools aren't expensive, but they are essential for programming your car's chip.
You can also use an unreprogrammable key that was programmed for another vehicle. In this case, make sure that the key has not been damaged or the transponder has not been altered in any way. The chip can be read with a scanner, or a computer that has an USB connector.
Reprogramming the transponder is a straightforward procedure, but requires special software. It also requires the use of a scanner. If you're a beginner it is recommended to seek help from an auto locksmith. It is also recommended to avoid purchasing second-hand keys as they are likely already programmed and will not be compatible with your car.
EZ Installer
Prior to recently, car owners who wanted to replace their keys were required to go to a dealer to have it digitally paired to the vehicle. This is because in order for modern keys to function they must be "paired". This required expensive and complex equipment that was only available to dealers.

The EZ Installer eliminates the need for expensive monthly service contracts and software updates. This lets retailers save money while offering their customers the same high quality service as OEM equipment.
