Restore stock lock screen from Go Launcher

[losl]

My N5 is non-rooted
I installed Go Launcher, Go Locker and Go Lockscreen and play around. I can switch launchers easily.
But after switching back to Google stock launcher the Go lockscreen is still activated and displayed.
I am unable to find a way to change back to the stock lockscreen with the stock launcher. Is there a way to
do that without uninstal the Go Locker and Go Lockscreen?

Thank you, have a nice day!

No, it would't work.

It only changes the launcher from Go Launcher to the stock Launcher after selecting in the options popup.
The lock screen is unchanged, it comes from Go lockscreen.
