Copying Schlage Primus secure keys In the United States, the secure key market is being challenged. MIT students demonstrated that it is possible to duplicate a Schlage Primus security key, one of the country's leading manufacturers, with a simple 3D scanner and 3D printer."Often imitated, never copied" is Schlage's slogan. The company will be able to review its arguments because the demonstration at the Def Con hacker conference should frighten them.
Their key, sold as tamper-proof, was duplicated in a few minutes using software of their design, and of course you must have the key you want to duplicate or at least take a picture of it so that the software can recognize and reproduce the shape of the key.
Once the model has been reconstructed in 3D on the computer, it only needs to be printed at low cost, for example on Shapeways, and the two students who initiated the work announced that any secure key can be copied on the same principle.
They also specify that the only way to really secure these keys would be to introduce an electronic part and use encryption keys to make copying more difficult. Operating principle of a Schlage Primus key: Example of a low-cost duplicated key:
