License Activation​#

GM/Opel SeedKey 5-Byte Calculator uses a personal license file bound to the HWID displayed by the application and your exact BinUnlock profile name.

1. Launch the application and copy the complete HWID.
2. Reply to this topic with the HWID in the following format:

Gemini will quote your request, add a short wish and attach your personal file named exactly license.lic. Download that attachment and place license.lic next to the application EXE. No key needs to be typed into the program.

The license uses your exact case-preserved forum profile name. The native client accepts ASCII names up to 63 characters. The file is HWID-bound and uses the client-supported practical-lifetime term of 65535 days.

If the application still shows an inactive license, verify that the file is named exactly license.lic, is located beside the correct EXE and was generated for the HWID currently displayed by that installation.
