[QUOTE=Tx Firefighter]Exactly, Blue Beard is right. The key is softer than the lock tumblers for a reason. The key is meant to wear so the lock won't.
If someone had new keys cut and they still come out like the old key did, it's because the new key is an exact copy
of the old worn out one..

But I didn't have my new key cut from my old worn out one -
I had it cut from my spare, which admittedly wasn't unused, but nearly so. :p
