02 regal questions about keys

My daughter bent the ignition key somehow pretty bad its got the chip in it.Can wal mart duplicate these? if not where can i get another one at and are they pricey?. Any help appreciated.

The '02 Regal has the Passkey II. Either the dealership or Internet stores like Ebay. The resistor value of the pellet on the key has to be matched. I'll check to see if we have a link or we should have old threads. Just do a search.
