It is probably not possible, you have to unlock on premises using a signed version of the tooling on a beta version of the OS on the device.
Your key2 probably has a customer version of the OS running it, so it would never be able to be unlocked :(
I argued about this but eventually the security of the "ecosystem" takes over the usability of unlocking older devices so they can be used for something else.
