If the creature leaves the battlefield, the exiled card will no longer be encoded on any creature. It will stay exiled.

If you want to encode the card with cipher onto a noncreature permanent such as a Keyrune that can turn into a creature, that permanent has to be a creature before the spell with cipher starts resolving. You can choose only a creature to encode the card onto.

The spell with cipher is encoded on the creature as part of that spell’s resolution, just after the spell’s other effects. That card goes directly from the stack to exile. It never goes to the graveyard.

The exiled card with cipher grants a triggered ability to the creature it’s encoded on. If that creature loses that ability and subsequently deals combat damage to a player, the triggered ability won’t trigger. However, the exiled card will continue to be encoded on that creature.
