Narrative:

On climb out; while climbing through about 2000 ft MSL; we got a master warning along with right engine thrust reverser 'arm' and 'unlock' light. I was pilot flying; and we verified that the right (emergency) emer-stow button was illuminated and the captain pushed the right side emergency stow. The captain notified ATC of our issue and we were given a vector to a downwind to run our checklist while returning to land at ZZZ. We completed the checklist; declared an emergency; and following the last item on the checklist; to land at our nearest suitable airport; which for us was ZZZ. Captain notified the passengers that we were returning to land. We were vectored to ILS 10L for an uneventful landing.
