Thieves mostly obtain entry through windows, once ascertained the
house is empty they test the windows, typically one is found
unlatched, or they will break the glass. It's very rare that thieves
waste time with door locks... modern tumbler locks are not so simple
to bump/pick. Theives especially avoid burglarizing an occupied
dwelling, if caught the penalty is much more severe plus they don't
want to meet up with a shotgun toting resident.
