I recently acquired an 04 9-5 ARC, with no original key available. I have a Cut key from esaab, and 2 locally acquired transmitters[1 new aftermarket. 1 used]
The new one has an uncut key blank that may have a chip in it[?], the blank is like the cut key from esaab. The used one has a different, thinner profile key.
I don't know if I can add photos yet. Apparently not after several attempts.
