If you just bought one of those Kwikset SmartKey products, you may come to find out that when you install it, the keyhole is upside down. When I had this happen the included instructions were of no help to fix this situation. However, I read on the Internet about a tool that you need to get from the manufacturer (Kwikset) which allows the cylinder to be removed and then inserted back in the right orientation. I called the toll-free # for Kwikset Customer Service and they sent me one for FREE.
When the thing arrived it also came with instructions. Couldn’t figure them out. It wasn’t until I saw this video on YouTube which finally helped me connect the dots. The guy talks about using an allen wrench and a screwdriver, but I found it much easier to use the tool from Kwikset. Take a look at the video if you’re stuck. Hope it helps.
