Reheat the iOpener and apply it to the bottom edge of the Surface's screen for two minutes.

You may need to reheat and reapply the iOpener several times to get the Surface warm enough. Follow the iOpener instructions to avoid overheating.

A hair dryer, heat gun, or hot plate may also be used for more heat, but be careful not to overheat the Surface—the screen and internal battery are susceptible to heat damage.
