Stealth Key

The Stealth Key, invented by Alejandro Ojeda, is a unique security key that utilizes 3D metal printing technology. Unlike traditional keys, the mechanical security features of the Stealth Key are concealed within its design, making it challenging to duplicate. The key's locking mechanism differs from conventional lock and key systems through use of levers instead of more common pin-tumbler locking systems.

 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. This rendered traditional key duplication methods and patent protection ineffective. Consequently, individuals were able to duplicate security keys,  and companies even offered key duplication services using smartphone images.

 Manufacturing of keys  Unlike most keys, which are produced through key blank stamping and subsequent hole drilling, the Stealth Key is manufactured by 3D printing a metal alloy into the desired key shape.
