Tracfone A205G Unlock Help

I have about 50 Tracfone Alcatel A205G’s that I’ve been trying to unlock. There is no way to enter the unlock and I’ve tried a couple secret alcatel codes such as *#0000*CODE#, *#0001*CODE#, etc, but nothing works. I have the code, just need to find out how to enter it or unlock this phone with sigmakey. Any help would be much appreciated. Thanks!
