The Burg Wächter E700 is part of a series of unusual devices made by the German lock maker Burg Wächter. These devices are sometimes called lock blockers or lock guards, their purpose is to fill up the keyhole in old fashioned warded and lever locks that you may still encounter in some homes or in antique furniture. These are still made and sold in Europe where such locks are still commonly used.
The key is very unusual in both its size (it is larger than the lock it operates) and its design. Presumably the thick warding around the blade is to add strength to the key blade and create a keyway that makes it difficult to apply tension to the lock's plug.
The E series only uses 4 pins and appears to have a very small number of different pin lengths but the design of the keyway and small size still present a challenge when trying to manipulate one of these devices.
