You get the password from the journal,but its not in it!But its at the top of the ruins.
Simple you just use cut on the door
Stand in front of the door and use a water stone; instead of going to the 'Pokemon' screen, it will go back to the game and the door will open.
use cut at the door of ruins
There is eight fields in the room where the first locked door on Kisimir Ruins in Rune Factory One. To open the door, you need to first plant spring crops and wait until they mature. The crops that mature fastest are radishes.
it says cut the door, so go to the door then use cut with a Pokemon that knows cut and the door will open.
you need to get a wailord and a relicanth and go to pacifilog town and dive somewhere . the pokeworld will shake. go to dessert ruins and a door will be open
You find the symbols on the roof of the ancient ruins. and just press them in order to make OPEN.
If you mean the walls which have a code of Unown mounted on them, then one door says ESCAPE (use an escape rope to open), one door says HO-OH (have Ho-oh at the top of your party), one says WATER (use water stone) and the final room says FLASH (use flash to open)
The missing page is on top of the ruins, and shows the translation you need to OPEN the door in the ruins. (Push the rock over to reach the vines, climb and jump to the roof.)
Use the translation in the ruins to press the four teeth that spell "open", then press the nose to open the door. (see related question)
