Thanks! ..especially for the quick reply.

Very old thread, but hopefully someone will chime in. SO basic a question, but I gotta ask. Realizing these (straight edge, center cut) keys have chips in them and along with the fobs they need to be programmed to work for our vehicle. But, do the "cuts" in the keys for a particular vehicle need to match? I would assume they MUST match...?? My situation: I have an '18 Silverado, have an original key and fob, misplaced the 2nd set so I needed replacements. ...went on Ebay and purchased a new "OEM GM" key and fob (from separate sellers). The fob showed up, in a new UNopened GM package, all good there. The key however (from what appears to be a reputable seller), listed as a "New OEM GM key blank..." was in a GM package (albeit opened, taped shut) ...already has a CUT pattern in it. I'm already in the process of returning it, since it's listed as a "BLANK", and if it's cut (which it is), ...it's not "blank" in my opinion. I would think a cut key is good for only one lock cylinder, so a new cut key is useless to me, unless it matches my truck, ...yet what's puzzle me is I see multiple sellers selling what they are calling "blanks", yet the keys have cuts. Thanks in advance for any info, Kevin GM# 84540865 (Fob) GM#23209422 (key)
