Pushing buttons doesn't scream vandalism like inserting glue into a lock does.

As a less vandalism like attack, consider when your drunk neighbours attempts to enter your apartment instead of their own. The security "feature" of a lock out is just an easily triggerable denial of service attack.

I like doing it to corporate security folks after they try to dictate it in authentication systems. They usually seem to understand after it's done to them.

Oh, I like that approach. I will have to remember this "argument" against lock out.
