I noticed this before running through a lockroom yesterday. When I pressed the button to activate the doors, I got a message saying "You need a keycard to open this door."

It wasn't until I moved forward towards the wall that I could open the lockroom doors and proceed normally...

This never happened to me in the offices or lockrooms, but it does this randomly when I am in the Pocket Dimension. Weird.
EDIT: Now this happens to me with the lamps as well.

Maybe that strange lamp simply contains SCP-1703?

I just saw Markiplier play the game and he got this too. What happens when you open the lamp with an omni or level 5?

I tried to open it, and it just said "You inserted the keycard into the slot" (or something like that.) and then nothing else happened.

It will open or close the Checkpoint Room doors.
The hidden keycard slot on the lamp only opens or closes the Checkpoint Room doors that separates the Heavy Containment Zone and the Entrance Zone.
Level 5 Keycard or Keycard Omni is required to open the doors.

Secret ending time (Just kidding)
Edit: I have encounterd this a few times, it keeps bugging me, but I do know what it does, as it is mentioned above my comment somewhere.

Replying to yourself... good idea
