This’ll go straight to the golf thread I know, but there are 6 points of entry with various types of lock (not able to simply swap barrels in all of them apparently) so it’s going to be a hefty bill.
But as @skinny says, better to be able to sleep easy.
Cylinders, either euro, oval, Scandinavian or yale rim, are all easy to replace. Or a door that doesn't need external access, just superglue the key hole and shove a pin in it.
Lever sets with a new key are available for the decent mortise locks, rather than replacing the whole lock.
