    Welcome to Motor Vehicle Maintenance & Repair! Quite literally, you're going to need to send it back to whomever you bought it from and get it re-coded or get a refund. There should be some sort of warranty on it from them. Also, we'd ask in the future if you could please use punctuation & capitalization, as this is very hard to read as it is. Aug 8, 2022 at 17:10

    Note that I edited your question as best I could to try to make it intelligible but there are still very important details missing. Please EDIT the question and fill in those items.
