I have purchased an uncut RX300 key off of ebay & had it cut for about $25.00. I programmed it myself & it works great. I don't know how they did it, but it was a new, uncut key, but the remote area didn't look brand new. Maybe it was. But it is a Lexus branded remote. I think I paid $80.00 for the key. If you would like the e-mail address of they guy I got it from, I can send it to you....he might have another or be able to get another.
