Cheese Cave- Locked Door?

[VanEinstein]

I havent found a way to open this yet. I'm not referring to the one which leads to the Floral Seal. I've got that. There's a different barred door that doesnt seem to open for any key. You'd think I'd have found something for that by now (nearly the very end of the game), but I havent. Has anyone been able to open this, or is it just a teaser?

You will be able to open it towards the end of the game.

What keys do you have in your inventory?

[VanEinstein]

- El Cairo Key
- Pharaoh Key
- Royal Key
- Sanatorium Key
- Toy Key
- Al Capone Key
- Mafia Key
- Skull Key
- Jailhouse Keypass
- Cheese Flower Key
- Sesame Key

(11) - I take it I'm still missing something.

[Rabbit]

Nope, I see you've got the correct key already!

Hint:

Spoiler: show

It's a key that opens more than one door.

[VanEinstein]

Well, that's good news. I'll just try them all till I find the correct one. Thank you.

[Alikamou]

you could try the jailhouse passkey. if that doesn't work, then the skull key. can never remember specific one, but you got them all.

Turned out to be the jail passkey. Just finished the game the first time through now, no more than 5 minutes ago (hard Mode- I like to jump into a challenge). I wasnt exactly impressed with the ending (so I'll assume that it might have a more extensive ending for those that finish nightmare mode).
