Editing Key (lock) (section)

====Paracentric====
A paracentric key is designed to open a paracentric lock. It is distinguishable by the contorted shape of its blade, which protrudes past the centre vertical line of the key barrel. Instead of the wards on the outer face of the lock simply protruding into the shape of the key along the spine, the wards protrude into the shape of the key along the entire width of the key, including along the length of the teeth.<ref>{{cite web |url=http://www.crypto.com/papers/notes/picking/ |title=Notes on Picking Pin Tumbler Locks |publisher=Crypto.com |date= |accessdate=10 June 2010 |deadurl=no |archiveurl=https://web.archive.org/web/20100322223449/http://www.crypto.com/papers/notes/picking/ |archivedate=22 March 2010 |df=dmy-all}}</ref>

Another way to describe a paracentric key is that the cylinders are not in a straight line, but can vary to the right or left, so that the key not only has to have the correct height of the pin for a cylinder, the pin is also extended to the left or right of the center of the key.
