After some research I've figured it out. I broke down the GPS coordinates from the pic, this is from an Otis elevator in a building somewhere along Köpfenstraße, Sieben. It is a DOM lock, DM11 profile. The bitting for this particular lock is 2-4-4-6-2, go to any local locksmith and ask him for this key. If he says he can't give it to you, this is standard procedure. Just tell him, "Der Ministerium für Staatssicherheit übernimmt die Rechnung". He will give it to you from a box under the counter. Schönen Tag noch.
