Honda/Acura/Toyota have used similar systems for years; this is one of the reasons why cloning a key costs less flagged hours than making a new one for an owner that lost all of them : when you lose all of them you need to get the actual computer out and pair it with the ecm directly, when you clone them there is a ritual that can be done with the other keys+ the new one.
