Finally found a place to cut the legacy key. unfortunately it is too late for the switchblade as I already hacked the valet key and expoxied it in. results aren't spectacular so looking to get another switchblade shell.
Xluben, I'd def be interested in a couple shells as well, let me know if you need any help with this deal. The switchblades are very nice quality as well.
This is a reliable source for the correct 11/12 legacy key for us 11/12 wrx/sti guys. Ebay is not reliable as I now have been sent the 10 legacy key advertised as the 11 twice. This place is a bit pricey but you will get the correct key pretty quickly.
