I bought one of these. Had the local hardware store cut it to match one of my keys. Followed the programming instructions in the owner's manual with my two other keys. Works like a charm. Keep it on the keychain that I keep the key to the wife's VW on. Works great for me. Would highly recommend. Oh, my car's an 07 focus. Even with the remote removed from the assembly, the car will still start - so it has a PATS chip in in.
