Script Crashing Game On Android Device (Unity 5)

This is a Car Door Script for i wrote in unity 4.6 version. I upgraded the project to Unity 5 and script works in the editor with unity remote. But when i build it to my phone it crashes the game.

Is there anything in this javaScript that causes my game to crash?

And yes you can use it in your own projects.
