I wish it only cost $4 to get my car key and house key copied.

The car key would be cheap if I just wanted one without the transponder for the doors, but the house key is still $10+ to copy. That's kind of the upside and the downside to high-security locks.

On a side note, I also pay for Onstar with my truck which, despite the varying opinions on it, is actually kind of nice to have. A buddy of mine needed to get into my truck when I was away, so I called Onstar, gave them my super-secret-squirrel-code, and they unlocked my trucks door over the phone. When I called my buddy back he wanted to know how in the hell I did that.
