Very small, precision needle-nose pliers work as well, but there needs to at least be a very small part of the key-break to grab. If the key somehow snaps in a position that’s even slightly recessed, I’ve used a tootpick and tiny dab of superglue (not enough to spread and touch the lock itself - be careful lol).
Spring-Summer: 18 (if hotter - underpants)
Fall-Winter: 3 (if colder + sweater & balaclava)
