Hard time finding the missing sigil's keys

[Falco]

I am missing two sigil keys, and I already know where they should be:
Mechanarium, and Vault .

For the first one, I never seem to have a good layout to get them, or not seem to have enough gear rooms. For the second one, I cannot find the vault key. I have opened already 2 vaul spots and the family one.

Do you have any suggestion on how to get the missing sigilis?

Beyond the obvious things like patience and making multiple attempts,
for 1) Consider room placement. It might affect how many doors you need to achieve success.
for 2) I had repeated success by trading items at the Trading Post. That's the only place I've found it, although apparently it can spawn in many other locations.

For the Mechanarium, the easiest way I found to do it was with the Aquarium upgraded to the Electric Eel Aquarium, which makes it a gear room. Then you just get an experiment that adds 3 aquariums to your pool each time it triggers. You'll have no problem setting enough rooms to make all eight doors appear.

For the Vault, you're just going to have to get lucky. The safe deposit box keys are rare, so I tended to stick them in the Coat Check whenever I got one so that I would have it available when I next drafted the Vault. There are only two more to get, so you're 50/50 on the next one being the right one for you.

Have you crafted all the items you can craft? One is very helpful with the mechanarium.

As for the Vault I'd suggest drafting the Trading Post; use it towards the end of a run and try to see if anything becomes what you're looking for.

Thank you all for your input.

I've already tried with the Trade Post and I have enough allowance to buy the whole Showroom but problably I am not getting lucky.

I've crafted every item possible, but I haven't used any in the mechanarium. Would you mind explain youtself? Are you implying I could use the Power Hammer to break stuff?

I mainly get offered vault keys when I offered other major keys (not including the master key).

The electromagnet increases the likelihood of drawing mechanical rooms. There are other tips I can give on placement etc. but I think that bump in probability will be enough for you to get traction again.

The number of gear rooms is not the only way the current floorplan affects the Machinarium.

Oh I didn’t know it! Thanks, I’ll try!

You mean that I can put it as a dead-end with many gear room thus the doors will be the “side” doors? because that I already know, I just hadn’t had the chance to try! Anyway, thanks
