You can also find replacement keys fobs on various websites and in many brick-and-mortar auto shops. How can you know that the one you purchased is genuine?

Transponder chips Car keys with transponder chips require a special programming to function. While any hardware store can cut a new key for you, the main problem is to make it work in conjunction with your particular car. The key you reprogrammed needs to match the specific identification number of your vehicle otherwise it won't even start the engine. Transponder chips are a common feature in modern cars and are designed to stop car theft. The chip is a microcircuit which transmits a radio frequency signal when the key is put into 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 in the vehicle. The car also shuts down if a frequency is not valid. This makes it difficult for thieves who aren't experienced to hot-wire a vehicle and then start it. The key and the chip are connected by an electronic circuit board that contains an induction coil. When the key is put in the ignition it creates a magnetic field created around the transponder. This generates a signal that gets absorbed by the coil, which sends it to the key's identification number. 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 ways to program a transponder, but all of them require an instrument that is specifically designed for. These tools can be bought online or from most automotive locksmiths. They're not cheap, but they're vital for programming the chip to your car. You may also use a reprogrammable key that was previously programmed for an alternative 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 by using a scanner or a computer with an USB connector. Reprogramming an transponder is a simple process, but requires specific software. It also requires an scanner tool. It is best to consult an auto locksmith for assistance if you're a novice. You should also avoid buying secondhand keys, as they're probably already programmed and will not work with your car.
