Well its promising that the key with remote is for that car. I might give Toyota a call and price a key for my VIN, then that would tell me if it has the keyless entry already in it (which I am certain it does now, being a later model and the Sports Ascent). Ive emailed a few locksmith's and they quoted around $240 for a immobiliser reset and master key - although it might be a bit more if he was just pricing the normal key without the remote, so thats the route I'll take if I can confirm from Toyota that the correct key is the one with the remote keyless in the head. $3800, the car is not worth much more than that! If it ever came to that, I'd buy the complete set of locks, immobiliser etc from a wreck and swap it all over :)
