On this other → Locked Amplifon thread I believe those were newer hearing aids (ReSound One’s) newer than LiNX Quattro. So I think we are dealing with a different style of locking than the locking mechanism encountered in that other thread. GN ReSound has a long history of locking hearing aids as referenced in this clip from Costco Hearing Aid list. Sad part is; we never found a solution for the older ReSound locks.
