If your original ECU is still available, the cloning option is ideal: fast, plug-and-play, retains mileage and key pairing.
On a tight budget and able to handle programming later, a virgin unit (blank) is a solid choice.
Avoid a locked unit—this is tied to its original vehicle and likely won’t work on yours.
