My topper door latches-namely the key hole on the outside part has a pretty standard key hole and the little cover just inside (before the actual keyway) is very stiff to move aside and get the key into, I have tried CRC spray, WD 40, ect to no avail, anyone know what I could use to get these to work? its very frustrating to get the key in now! Thanks!!

 

what you need is about $20. I just replaced mine for the same reason. The dealer info was still on the topper. I drove in, asked what it would take, $20 and 10 minutes and I had a new one installed
