2010 Dodge 2500 6.7L Cummins will not start intermittently if does not unlock with fob and if dash does not turn on with key. How do you reset antitheft?

 

I have this problem occasionally with my 2011, I found that taking the cables off the batteries and tying them together (positive to negative, both sides) will reset the brain in the fuse box. I have done it twice and haven't had a problem for 3 years now.
