Key programming is done with dedicated software. I bought it because it seemed convenient, but I can't use it all, so I'm selling it. The original price was about 4000 yen. Only the main unit and cord are for sale, so it's for those who know about it. There are no noticeable scratches or stains, but it's a used item, so please do not contact me if you are sensitive to this. I have many other items for sale, so if you purchase them at the same time, I will give you a small discount.
