2012 ml 350 roof rack problem !!!

hi all

i have an urgent question. it will likely sound dumb but still requires help. 🙃

i got a new 450 roof rack installed earlier this year and cant seem to get it unlocked ! 🙄

i inserted the key and turned it and tried to lift the lid and nothing. the only instructions are about how to install it.
also theres like a rubber tube or two that came with it that i have no idea what its for.

i think i have the correct key. its a mercedes benz roof box and has mb on it. is there a handle to lift or do you lift while turning the key?

it’s urgent cuz i am moving in a couple days and need to know how to get it open foe the extra storage i need.

embarassing question but all help is appreciated!
thanks everyone

You will have to contact the company that produced the rack and tell them your problem, as they are the only one who can supply you with a new key.

You tube video which shows how an MB luggage carrier opens @ 1:00

Besides that, I agree that you should contact the installer or MB dealer for more guidance.

Chances are the key needs to be turned to unlock the box. This got me thinking - maybe it needs to be pushed in to release a latch maybe? Like old cars' door handles used to be. Not sure, just guessing this. I found interesting the part where he uses both hands to lift the lid. Perhaps there is something about where his hands were... leverage maybe? I would not think to use both hands to lift the lid, I would think that you could just lift with one hand from the center of the lid right above the key, but in his case, he didn't do what I thought was the intuitive way.
