Narrative:
Aircraft had a loud squeal from the service door. Pressurization was deferred in automatic and manual mode per MEL. MEL requires both outflow valves to be secured open with opening tool. Maintenance resealed rubber door trim and lower service kick plate in accordance with 52-00-04-300-801-a; with a notation that the MEL item was restored. Aircraft left and was unable to pressurize aircraft in automatic or manual mode. Upon further investigation it was determined that the outflow opening tool was not removed from the outflow valves. MEL was not restored properly and an operations check of the system and the noise from the door was not performed.
