There's no reasonable explanation, but Smith is an ex-agent. He still probably has some abilities from when he was an Agent.
Therefore, he could get in, since programs like Agents and Smith have a knack for appearing out of nowhere.
2nd possiblity: Smith sneaked in behind them, took a door as soon as he could, and appeared in another room.

Not really, but IIRC, the Twins actually stole the key from the Keymaker in EtM. How Smith got access is another matter, but obviously the Keymaker and Seraph were not the only people with access to the hall of doors. Smith probably assimilated someone who had access (just no one we knew about). The Keymaker states that the only way to get to the room of doors is to disable the power, open the first door, then find the second and open it.Now I understand why the power had to be cut off to get into the room full of doors, because that was the access to the Source.But why did they have to cut the power to the building to get into the hallways? The Keymaker never said the power *had* to be cut in order to get access to the hallway (Seraph used the hallway as a shortcut with Neo & the Oracle earlier in the movie, and Ghost/Niobe were in there during EtM). The power only had to be cut in order for the Source to be accessed. Since there was no way to contact Neo/Keymaker once they were inside the hallway, it just made more sense to cut the power up front before they ever went inside, so they would know as soon as they got to the Source that it was safe to open the door. If not for Smith getting in the way, it would've been a relatively short trip. Why indeed did they even need to go THROUGH the building, when the Keymaker proved that he could get in and out of it however he wanted? Each door only leads to one place in the Matrix, and because the hidden doors are spread throughout the world (or at least the megacity), I think they had to go through the building only because the hidden door they were closest to after saving the Keymaker happened to put them at a distance from the door leading to the Source. We don't know exactly where the Keymaker appeared when he slipped in and out to avoid Smith, so it might not have been feasible for them to travel through the Matrix just to find a hidden door that put them close to the Source, when they could use the door closest to them and travel through the building (not expecting Smith to appear, of course).

If I've understood this question correctly, the answer should be pretty easy. The door in the "room" where the Keymaker died (which was not the hallway anymore) simply wasn't in the hallway. In order to access it, you needed this special key and enter it from that hidden floor in the secured building. There simply wasn't any access to it directly from the hallway, only to the floor -- which was secured by bombs.

Thanks, I knew it was stolen by two people from the movie, I just couldn't remember which two.. :smileyhappy: And they were able to get into the Industrial Hallway beforehand. <snip> The Industrial Hallway is not protected by anything other than the need for 'sploits to get inside. Where do you get 'industrial hallway"?
