A key that has been reprogrammed will need to be compatible with the exact 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 which transmits a radio frequency signals when the key is put in the ignition. The car then scans for the signal and begins the engine if it is in line with the original one that was programmed into the vehicle. The car will also shut down if a frequency is not valid. This makes it more difficult 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 inserted into the ignition, it creates a magnetic field around the transponder. This generates a signal that is absorbed by the coil and sent to the key's identification. The ID number of the key is transmitted back to the vehicle and if it matches the engine will begin to run.
