the.com/skeleton key
A lock's ultimate backstabber: one shape, every door, zero loyalty.
means A key filed down to a bare minimal shape so it can open many different locks instead of just one.
from From 'skeleton' in the sense of a stripped-down bare framework — the key's bit (the business end) is filed back to the barest essential ridges, shedding the specific wards that would restrict it to a single lock, leaving just the 'bones' needed to trip a mechanism. The term shows up in English by the 1800s alongside the locksmith's craft of cutting such bypass keys.
