In In re Lamont R. (1988) 200 Cal. App. 3d 244, a police officer discovered a trailer was open. The officer "closed the trailer doors, wrapped two chains around each other and hooked them into opposite bolts." ( Id. at p. 247.) Thereafter, the juvenile defendant and another male "unhooked the chains, unfastened the latches and pulled open the door." (Ibid.) There was no burglary because the juvenile defendant "used no pressure; he broke no seal; he disengaged no mechanism that could reasonably be called a lock." ( Id. at p. 248.)
