We purchased it to repair and sell. The thing has kinda grown on me but I already have a nice car 99 Audi Quattro. I would like to know what you mean by "key number car". Also I would like to add that we have both of the stickers that go under the rear glass still brand new on the paper backing. As well as 2 key blanks and also has the remote w/ the key still but doesnt work I think it just needs a new battery even though it tested ok on a volt meter.
