For the purposes of this poll/thread, a "Transformers room" can be any room where you keep your Transformers collection - whether it be a dedicated collection room, bedroom, study etc. I must confess that, until now, I've always kept my Transformers room locked when I'm out of the house, but usually not when I'm at home, and that includes when I'm asleep.
If reading this thread has made you change your mind, please vote according to what you've been doing before then. So I've voted the second option, but from now on I'm gonna keep my TF room locked when I sleep.
