The key you reprogrammed needs to be compatible with the specific identification number of the vehicle otherwise it won't even start the engine.

Transponder chips are a common feature in modern cars and are designed to prevent car theft. The chip is a microcircuit which emits a radio frequency signal when the key is placed into the ignition. The car detects the signal, and starts the engine only if it matches the original that was programmed in the vehicle. The car also shuts down if the frequency is invalid. This makes it more difficult for novice car thefts to hot-wire a vehicle and then start it.

The chip and the key are connected via an electronic circuit board that contains an induction coil. When the key is put in the ignition it creates a magnetic field generated around the transponder. This creates a signal that gets taken up by the coil, which sends it to the key's identification number. The key's identification code is returned to the car, and the engine starts if the identification number matches.
