That's the way to do it.
Programming instructions are pinned in the IS200 section of the forum. Any issues, PM me.
I have a pre-cut key spare (internal electronics is the only bit ya need), think is a two button, but I have used it as a master! PM me if interested, I'll have to find it!
I think I also have a flip-out style blank case, though with holes for three button internals. If anyone is interested, I'll check them out and post a thread.
I beleive this is the conclusive test for all IS200 (others Lexus too, I think.)
phew, yeah its a master just checked on my lunch break lol
Yeah would be very interested in the pre-cut key and the flip out ones, cause i like those styles, the flip out one would i need the same things as with the standard ones?
