Im just cant hook it, i've tested on other save's. Im doesnt have sandbox, so im cant delete doors and get it. Any ideas how to get the keycard?

EDIT: I've tried a lot metods, like try to press C and get into bunker, chair bug metod and etc, nothing worked.

same here - even tried detonating a fuel canister right beside the keycard (hooked the canister, slotted it in, and then kept chucking it at the stairs), but the keycard didn't even move despite being more or less hit directly when the thing exploded.

I'm having this issue too, cant hook the keycard :(

Apparently it's bugged on this version, Download the old version, i was able to grab the keycard fine in 0.9i, but don't overwrite the current just have 2 votv installed then start a new save on the old version, run and grab some m.r.e inside the log next to the river and sell them then buy the hook and grab the keycard then put it in mailbox. quit old version, start new version and grab keycard from mailbox in your current save. you can download old version from the votv archive.

Cat someone share save with a card maybe?
