2012 NV2500 HD fob programming problem

[RandyJ2007]

I have searched every way I know to and have not seen anything like this problem or a solution to it.  If I am doing something wrong I don't know what it is.  I have a total of 4 fobs.  2 old and 2 new.  Per the instructions, I enter the van, shut the door, press the lock button, insert key in switch at least 6 times until the emergency flashers blink twice, turn the key to ACC position, press the lock button on the remote.  To program each additional remote I press the unlock then the lock button on the door then the lock button on the remote, lights flash two times.  When completed turn key off, unlock door, exit vehicle.... when I press the lock button the horn blows off and on until I get in the van, start engine, and turn off the engine then remove the key.  What is going on?  Why is the van responding this way to the procedure?  Two of the remotes worked before the batteries died in them.

For both our Xterra and NV, we bought Rogue combined keys and fobs to replace the separate ones supplied. Our local Nissan dealer readily programmed the new keys to work at not much $$$
