Record Locks on Subforms

This may be an obvious question. If I apply record
locking to edited records, does the lock apply to to child
table as well? In other words, a form has a subform that
draws its data from a child table (duh!). A user is
currently editing one record on the main form and the
edits affect only the parent table. Can the subform data
(child table data) for that record be updated
simultaneously?

Let me clarify "be updated simultaneously by another user"
