Dang expensive keys, POS.
The OEM key for my El Camino had a failure. The ignition key broke. The door key is so worn out no one but me can make it open the door. Ya, gotta hold the key just right and lean to the right tilt your head to the left and stand on one foot to get the door to open. I can do it in a heartbeat, but my wife can't ever use the original keys.
So I had to get some new keys. The replacements cost me a whole $5.49 for the two new keys. I would love to punch the guy that decided a Chevy needed to have two different key to operate the car. I figured I might as well splurge and get a new pair. I am not sure how to figure out how much per mile that cost me, but is is a tiny fraction of a penny per mile.
