Here's a link to kwikset's install for your deadbolt. It looks like the plate should just pop off and the backer paltae behind it has the screws that need tightened.

Here is a link that might be useful: kwikset install directions

Like sierraeast's link shows, that little hole in the shaft should have a set screw in it. You need a small allen wrench to unscrew it, and then you can remove the thumb latch. Unfortunatley it does not say what size you need as it is provided with the lockset.

Hopefully they figured it out by now Steve as the post 4 1/2 years ago.

I just used that info last night. Helped me quite a bit in fact. (Prevented Steve from taking a Ball Peen hammer and crow bar to the deadbolt for example) and I thought I would add the allen wrench size so the next guy could just locate the one wrench not but a $8.95 combo tool from HD....

Sometimes it is nice to have more than one size of Allen wrench....

Thank you Steve. I was recently doing something to my quickset. It is good to know the size I would need

Thanks Steve Taylor!

I needed that info.
