Vizio remote menu button not working?

I have two Vizio tvs, a 42" smaet smart tv and a 32" regular. Remote to the 32" has been missing for some time, so I bought the basic Vizio replacement remote. The problem is, both remotes work fine on the 42" tv, but neither will access the menu button on the 32". Any ideas?

You may need to program the remote. Read the instructions.
