You can pop many locks with application of a simple crowbar and/or Z-angle pin stack. Makes getting locked in or out a non-issue unless you get caught in the act.
Actually, not to harsh yer lock-poppin' buzz G, but most of those gates are locked with not one, not two, but 4 or 5 locks, and moreover are encased in these little fortified enclosures that Norman Schwartzkopf would have trouble penetrating.
What he said about not busting locks... It's not going to help the situation in the long run. A slight tangent, but those multi-lock gates, in my experience, will open by unlocking ONE of the locks; there are multiple locks there for multiple users. That way if one user changes locks, not every user group has to change locks.
