Product review (5 stars): Right Part - EASY for DIY Lock Repair
This arrived super fast, and was exactly the right part for our Samsung washer door.  There is a youtube video that shows how to replace this yourself (about 3 minutes long) and it was very helpful.  DO NOT PAY $200+ to have this part repaired.  I did it myself in 20 minutes.  If you are really fearful about repairing it yourself, at least order the part for 50-75% less than you would pay a repair person.
