How can you know that the key you purchased is genuine? Can you tell whether the unit is programmed to work with another vehicle or if it could be programmed again?

You will only have just a few seconds before the car's system resets commands and leaves programming mode. It is essential to move quickly and do not be patient between each step. To avoid this happening, turn off the engine. You can check the car's system by turning the key to the "on" position and then back to the "off" position.

Certain cars with more modern technology have rolling key technology that keeps thieves from using a stolen car's key to open it. This feature is still susceptible to a technique known as a replay attack. It allows thieves to record and duplicate the signal generated by the key fob of the vehicle to open the car.

Transponder chips
Car keys with transponder chips require a specific reprogramming to work. Any hardware store can offer you an entirely new car key, however the real challenge lies in implementing it to your car. A reprogrammed key will need to be compatible with the specific identification number of your vehicle or else it won't be able to start the engine.
Transponder chips are a standard feature of modern cars and are designed to guard against car theft. The chip is a microcircuit that transmits a radio-frequency signal when the ignition key is placed. The car then scans for the signal and begins the engine in case it matches the original signal that was programmed into the vehicle. The car is also programmed to shut down if it detects an invalid frequency. This makes it more difficult for thieves who are not experienced to hot wire a vehicle and then start it.
A circuit board with an induction coil that connects the key to the chip. When the key is placed in the ignition it creates an electric field around the transponder. This produces a signal which is amplified by the coil which transmits it to the key's identification number. The key's identification number is sent back to the car and the engine will start if the identification number matches.
There are several ways to program a transponder key but they all involve using a special tool. These tools are available on the internet or at most auto locksmiths. These tools aren't cheap but are essential to program your car's chip.
You could also use a reprogrammable transponder key that has been previously programmed for a different 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 an USB connector.
Reprogramming a transponder is a simple procedure, but requires specialized software. It also requires an scanner tool. It is recommended to contact an auto locksmith for assistance in case you're not an expert. It is also recommended to avoid purchasing secondhand keys, as they're likely to be programmed and won't work with your car.
