- I'm looking for a door lock that is opened from one side using a
splined key but I want one with an individually coded splined key ,
not a universal Does anyone know of anywhere I can buy one?

all those I've been able to find on line use the same universal key

Either Chubb or Era do a splined lock with a removable key (like a small
cylinder key)can't remember it's part no offhand.
