I'm dressed normal, I have the Passport, the Robot won't talk to me, the door says Requires Key, what is going on? I just finished doing all the quests for the Boomers, what went wrong?

Edit: It's okay, I got it.

"Console Fix (PS3/Xbox360): You need to use the Monorail to gain entry into the Vegas Strip. It can be found at McCarran military base. You need to be wearing NCR armor to pass the guards unharmed. This will get you into the city and should fix your glitch (heard a patch is on the way)
"

You dont need to wear NCR armour, i don't know what i did.. but i can use it whenever i want wearing whatever..

They must think im one of them.. :confused:

If they like you then you have more leway with them.

Hmm, I did not find the Monorail when I was at McCarren........

It's above the botony room on the first floor of the McCarren Airport. Go up the shut down escalater and it'll be on the far left side of the map

Oh really, hmm i only did a quest or two for them.

and i found it by going through the vegas side haha.

As i posted earlier in another thread its also possible to one shot the securiton from a long distance with a sneak attack and you loot the key from his remains. If you do it this way nobody knows it was you ,so you dont get any rep hit , nor does it have any impact on anything else.
