A key that has been reprogrammed will need to match the exact identification number of your car otherwise it won't even start the engine.
Transponder chips, which are used to stop theft of cars, are a common feature of modern automobiles. The chip is a microcircuit that emits a radio frequency signal when the ignition key is inserted. The car then scans for the signal and begins the engine in case it matches the original frequency that was programmed into the vehicle. The car is also programmed so that it will shut down when it detects an incorrect frequency. This makes it harder for thieves with no experience to hot-wire a vehicle and then turn it on.
The key and the chip are linked by a circuit board that includes an induction coil. When the key is placed in the ignition, a magnetic field is generated around the transponder. This creates a signal which is taken up by the coil before being sent to the key identification number. The key's ID number is sent back to the vehicle, and if it is in line with the engine will begin to run.
