coplot() usually puts grid lines in the panels it makes. To see examples,
example(coplot).
How can I remove those grid lines?

That's hard-coded in coplot. But you can easily make a
modified copy of coplot. Here are the steps:
1. make a copy of coplot; call it mycoplot.
2. add this to the argument list of the function:
col.grid = "lightgray"
3. find this line in the code:
grid(lty = "solid")
and change it to
grid(lty = "solid", col = col.grid)
4. source() your new function.
It wouldn't be a bad idea to also do
environment(mycoplot) <- environment(coplot)
Now just set col.grid = "transparent"
(or col.grid = 0 should also work) when you
want to suppress the grid. This also gives you
the option of using other grid colours.
