The Stealth Key, invented by Alejandro Ojeda, is a unique security key that utilizes 3D metal printing technology.[1] Unlike traditional keys, the mechanical security features of the Stealth Key are concealed within its design, making it challenging to duplicate.[2][3][4][5] The key's locking mechanism differs from conventional lock and key systems through use of levers instead of more common pin-tumbler locking systems.[1][vague]
History The concept of the Stealth Key emerged as a response to the increasing accessibility of 3D printers and scanners in the consumer market around the early 2010s.[6] This rendered traditional key duplication methods and patent protection ineffective.[7] Consequently, individuals were able to duplicate security keys,[8][9][10] and companies even offered key duplication services using smartphone images.[11][12]
Manufacturing of keys Unlike most keys, which are produced through key blank stamping and subsequent hole drilling,[13] the Stealth Key is manufactured by 3D printing a metal alloy into the desired key shape.[4]
