Replacing the shell without moving this chip will lead to a car that cranks however will not begin.Moving the Blade: Owners have 2 choices: they can either move the initial metal blade to the brand-new shell (if suitable) or have the new blank blade cut by a professional to match the original.Assembly: The electronic devices are seated into the new shell.
