Keynote Manager can operate in two modes:

In either of these modes, Keynote Manager needs to ensure multiple users do not overwrite each others’ work. To achieve that:

Edit Locks

When a user edits a keynote, Keynote Manager will write some info inside the keynote file (hidden to Revit) that a user has borrowed that specific keynote for editing. If you have a sticky lock on a specific keynote, manually clear the content of Locks Table in the keynote file. These locks are written in between the two lines below

# --------------------- @table(locks_table:"Locks Table")
>>> locks are listed here...
# ===================== @db(keynotesdb:"pyRevit Keynotes Manager DB")

For example a lock with id tf5n6dURvk+JrZQ5r3gD5g== exists in this keynote file example:

# @datastore("txt") @source("C:\\Users\\ehsan\\Desktop\\Keynotes.txt") ...
# ===================== @db(txn_db:"Internal DB")
# --------------------- @table(locks_table:"Locks Table")
# tf5n6dURvk+JrZQ5r3gD5g==	leo-wx-rir	eirannejad	w8/8rO/UOUyP0vs1oS53zA== ...
# ===================== @db(keynotesdb:"pyRevit Keynotes Manager DB")
C1	CATEGORY ONE
C2	OTHER CATEGORY
# --------------------- @table(keynotes:"Keynotes Table")

So to clear the locks, remove the lock lines. Coordinate this with your team so you are the only person changing the file
