I had a similar problem with a lock on the garage door so i swapped it with on on the small side locker. They are not great locks and chances are another will go soon but for now it saved me having to get a new lock. Also, the problem i found was the plastic mechanism rather than the lock itself. Might be worth taking it apart to see if you can do a job on it.
