It's right in front of your face when you turn the game on. If you want to access it but are in a dungeon, you have to save, turn the game off, and turn it back on again.
The London Dungeon first opened in early 1965.
Just head on back down to Spacial Rift once it's open to you again. Beat Palkia again, and you'll be able to recruit him right then and there.
There is no key to the dungeon. The small key open Mordred's underground laboratory, which has a back way into the dungeon. (see the related questions)
They don't open dungeons, they open locked rooms within dungeons. Certain unique items can be found, like the Silk items, and treasure items for Legendary pokemon.
The dungeon entrance in the library does not use a key. Get the coin from the fountain, then the library slip from the Mordred Museum. Now you can open the secret passage in the castle library (Non-Fiction McM). However, once the dungeon is guarded, you will need the key to Mordred's laboratory to reach the cell again. (see related question)
