What can you do with CL4 keycard as D class?

Solution
Discover CL4 documents and info leak them so long as you have a printed copy, close BH doors, enter electrical sites to toggle lights or teslages on and off.

You can explore non-coded/biometric CL4 areas such as Floor 3 (to an extent), SCP-682, SCP-079.

You could even use it to get to surface (however you can do that eith a CL3 so long as EZ bulk head door is not closed).

There are many things possible, just got to avoid being caught!
