Hi,
I don't think I understand what you are asking.
If you are refering to the instrument's front panel, which locks when the instrument goes to remote mode, then it depends on the instrument how it can go back to local.
Some instruments will go to local by pressing any key, others a particular key. Refer to the instrument's documentation.
There is also a NI-488.2 function that makes the instrument go to local: ibloc.
Hope this helps.
