You can't pass two macro parameters, then use them with one name inside the
macro.  Fortunately, you can still call the macro the way you are doing, but
the macro itself will have to be written to receive all 5 arguments,
something like:

key_tog  macro   key, bit1_reg, bit1_bit, bit2_reg, bit2_bit

This isn't that bad since the main code will still look the way you want it
to, just the macro will look a bit different.
