SDCL § 59-11-10: Service of process until new registered agent is appointed.

When a commercial registered agent termination statement takes effect, the registered agent ceases to be an agent for service of process on each entity formerly represented by it. Until an entity formerly represented by a terminated commercial registered agent appoints a new registered agent, service of process may be made on the entity as provided in §§ 59-11-16 to 59-11-19, inclusive. Termination of the listing of a commercial registered agent under this section does not affect any contractual rights a represented entity may have against the agent or that the agent may have against the entity.
