Yeah, ALWAYS give yourself a back door into your database--a way to re-enable the shift key bypass. Here's a quote of mine from another thread on this topic:
The way I do it is that there's a button only visible to people in the admins group. Clicking on that re-enable's the shift key, so the next time you open the database the shift key will be enabled. Another button (or the same one, or a toggle, or whatever) re-disables it. Hopefully you've got a copy of the database that hasn't yet run this code!!
