Software or Hard Reset Kenwood NX-210

I have bought several Kenwood nexedge radios for work and this is the first one I had issues with..   it is Kenwood NX-210 RR and has password.  Already had KPG-111D programming software.   Of course both radios are locked..
 contacted the original owner of radio's embedded on it and not been able to get a call back..  i read on previous forums that say you can try and write a blank new file and did not work.  Does Kenwood have a factory password, or a hard reset for the radio or have any suggestions I should try.   I have searched more radio's and have noticed several Kenwood NX-210 radio's originally from BNSF are locked.   Any help will be appreciated.  Right now I have them programmed for only VHF but would like to add the NXDN channels if the east coast ever adapts to it.

Here is the master BNSF passwords for reading and overwriting they are as follows READ AUTH IS 706857
OVERWRITE IS 703817 So give these a try when attempting to program a kenwood NX-210 BNSF radio hope this really helps!!!!!!!!

Hello everyone?!

Well, now that we have the BNSF. Imma just ask right away if anybody here’s got the master password for Union Pacific for their NX’s also(if they have any)?

Please let me know in PM if you have it?
Have a great day and many thanks in advance! 

Railfan51 Thank you so much for the assistance it has had me puzzled for awhile and just now went back to try and figure it out after I bought several other radios from govdeals.
