Sanford B Elgin , SC August 10, 2015 The handle had broken on the lg microwave that i own the locking key had previously broken I found a video on you-tube from appliance parts pro and was able to see how the repair should be done. I was confident that I could do the repair myself and ordered the parts. It took less than 10 minutes to replace both the door handle and the locking key. 2 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: Less than 15 minutes
