VIRGINIA POSTREL WRITES:

If you go to Lowe’s to get a key copied, you have a choice. For $1.24, you can get a standard brass key. For $2.97, you can choose from a half-dozen colorful patterns — flowers, American flags, tie-dyes, flames.

The more expensive key will not open the door any better. The difference is purely aesthetic.
