I talked to Benny through the intercom, killed his guards and now his room key. But when I go to the 13th floor and go to his room, it says I can't open the door without a key.

Help. What do I do?

Thanks

Benny's room shouldn't do that, I'm pretty sure it is only an "Average" locked door.

You shouldn't have killed the room key.

yeah it is just an average lock.did ya break the lock.i dont know for sure but i think there could be another way in coz there is a secret tunnel you can leave his room by and it leads out of the hotel.well its not exactly secret its right there in plain sight but you know what i mean.i dont know were it leads though coz i always went the normal way out but if you let him go instead of killing him he runs away through this tunnel.maybe someone else knows where it leads and if you can get in this way?
