There is a security cupboard on the laboratory corridor.
How to open it?
Yes, I can access the elevator
What am I supposed to do to the cupboard?
I can tell you won't find a key into it. Have you explored Totel's office and got access to the elevator, yet?
Read some books to get hints. ( There is a book in the display case at the basement about lock picking. )

You should pick the lock on the security cupboard.
