TSA Keys - 002 and 007

TSA keys demonstrate several lock-related security concepts:
- the ability to copy keys from an image
- insecurity caused by manufacturers installing locks that are keyed alike
- the inability to "patch" physical hardware when vulnerabilities are discovered

Though TSA locks are trivial to pick, having a set of these keys on hand allows you to demonstrate these concepts hands-on.
