No they do not, it's explicitly stated in the event details and in-game FAQs page for chest events, ALL silver keys dissappear, not just inventory, anywhere including gift box, which is why you always use up all your silver keys before the event end. ONLY gold keys carry over from event to event so even though they guarentee chests can open, you should always use silver first.
