getting keys

[sparkeymark79]

is there a preferred weapon to use to help with getting the keys to drop so far on my old save, i have been running around using the spear, the pistol and the sword from furniture portal world. but since the up i have not got one single key from any captain i have been doing loops i cascade labs killing the one there the 3 or 4 in manufactory west and the one on the train portal world. could it be that im using a old save maybe ? any help would be great many thanks

Far as we know, there is no special condition that makes it more likely for them to drop keys (unlike the Rat with their Backpack drops).

It took several loops and dozens of killed Captains for me to get a key as well.

There really doesn't seem to be a way to cheese it, just a grind until you get it thing. I finally got one after several dozens captains killed.

I'm still working on getting one from the Symphonist, 4 organs collected (just enough for the full armor set) but not a single key has dropped :(
