This can be done by pairing read/update and rewrite command. If record is read for update(read/update) then it must be rewritten, if after read/update record is not required to rewrite then it must be unlocked using unlock command.
One more cause is for deadlock is double update in pseudo-conversational program and this can avoided by coding a update identifier field.
