It's hard to guess the details of your collision from only the scene views, so maybe more details would help.
One thing you should know is that marking a Collider as "Trigger" will have it ignore collisions with the world environment. So I take it your elevator is a "Trigger" and probably won't collide with anything.
If that's the case, I'd suggest ticking off the "Trigger" checkbox on the Elevator collider and adding another collider on top of the Elevator that activates the activation when you enter that one instead :)
Give that a shot, if you need more explanation, more details or if you have further questions or details for us, fire away, otherwise, please accept this answer ;)
