Sounds like the spring is bound up. Pull it and re-seat it?

I’ll give that a shot, I’m planning on doing a bit of a restoration on this one too. Super stoked to have my first Model M :)

It might take a few tries. If you place the M such that the back is facing the ground, it'll be easier as gravity will hold the spring in a good position while you put the key back on. This is really common on these keyboards if you're removing and replacing keys. (Ex: washing them) But not a big deal to fix. I hope you enjoy the buckling spring life! :D

My normal procedure (might be an easier way); I would pull the keycap and and put it back on (sometimes this will work when I do that about 5 times), if that does not work; I would remove the spring and seat it using the chopstick and straw method,(I would do this about 5 times as well and repeat the first procedure on each attempt); if that does not work; I would try a brand new spring entirely (and repeat the first 2 procedures entirely with the new spring). Normally I would fix the key within these trys and for REALLY stubborn keys it might not work until your 2nd or 3rd new spring you try out on it.
