Can't sneak into get fireworks

[Starkgambit]

Sandstorm happening, sneaking into the store room with Colton's help. How can I go into the next room? Other playthroughs have the 'sneak in' option but I can only see the firearms inside..

Help?

In case you haven't yet figured it out, you have to add the amount of the fireworks on the note together and use the code to enter from the main door

You can also just throw bottles from the window until you break the other room's window

Amazing! Thank you!
