I had a huge problem finding a spare key blank for my 2005 Aveo LT. Local Chevrolet Dealer wanted like $40 bucks for one. Eventually, I ordered online a 5-pack of Blanks # DW48R for about $12. Took it to a hardware store and they cut the key and it worked fine. Charged me $3 to cut my blank. My key does not have a chip in it.
