Just heard about this today and not sure what lock snapping is...I have a upvc door which I think is a good strong lock, but this ex-burgular states he would not bother picking them and he would just snap them...it is saying that in dec 27% of burgularies accounted for this method and it takes between 50 secs and 2 mins....maybe a locksmith on here can tell what to upgrade to...........
