NCR Ranger Safehouse - I can't get in
This appears to be a glitch that hasn't been recorded on the wikia.
Because of your liked reputation with the NCR and the key you received from Col. Hsu you should be able to access the NCR Ranger Safehouse. You should check your keyring to see if the NCR Safehouse Key has been properly added to your inventory; the keyring is in your Pipboy's MISC tab.
If, due to a bug, you never received your key to the NCR Safehouse you can add it to your inventory using this console command player.additem 00162998 1
.
If you do have the Safehouse key and you still can't open the door use the console command unlock
, click on the door, and press the enter key.
