Read the Manual: 30

Here is the question

On the back of the broken panel you see a recovery manual. You need to find the emergency repair key in order to put the robot into autoboot mode, but it appears to be ciphered using a Caesar cipher.

You can get the manual in the above link or you can download it here https://drive.google.com/file/d/0BxDZABox5hT2cWNacWw3RU85RzA/edit?usp=sharing

In the question they have specified that the file ( here recovery manual ) is ciphered using a Caesar cipher.

One may not be knowing about what cipher is here are some links which tell you the basics.

I think that you understood what a caesar cipher is, In this computer world you need not sit trying all the keys possible from A-Z instead you could use an online decoder for this purpose . The one which i used is http://www.xarg.org/tools/caesar-cipher/

Here you just paste the given text in the file to the box to encrypt just keep the key as guess and the magic happens.
