For some reason when i go to the Strip gate it says i need a key. Can i please get some help?

Try taking the train from Camp Mcarren to the strip, its on the left side of the terminal building

You can also get a key from the securitron at the gates. Make sure to stealth kill him or you'll have a mob of pissed off robots after you.

you can also get a fake pass at one of the shops in free side.

Go in holding 2000 caps

WTF, Didn't the patch fix this?
Oh and its the monorail or killing the securitrons (sniped from a large distance) otherwise you are permanently locked out of the strip.
Those other guys obviously didn't read what you had posted!

I had the same problem so i quit playing the game and that was the end of that chapter
Problem? - Solution

I had that problem too. I was running in and out of the Strip doing businesses and suddenly one day, it said I need a key to enter. So, I used the unlock cheat.
