Note that the rekey tool hole is on the opposite side of the keyway than with the KW1 keyway SmartKey cores:
The original KW1 SmartKey rekey tool would work, though the tools came with this one:
However, this core uses completely different tools to reset the core if the working key is lost. No reset cradle is made for this lock. The Better Resetter tool DOES work with this core, but you must use the Kwikset SmartKey side. It is a little fiddly, but it does work.
Here are the tools made by Kwikset for this core:
To rekey the lock, put the key fully into the lock. It is NOT necessary to remove the core from the housing to do this.
Turn the key counter-clockwise (anti-clockwise) 90 degrees, putting the rekey hole at the top.
Insert the rekey tool, and push it firmly in all the way.
Remove the reset tool, then remove the key by pulling it out without turning it.
Insert the new key.
Turn it clockwise and remove it when it is in the removal position.
The core is now rekeyed.
Now, how to reset the core if the original key is lost or is no longer working. First, remove the core from the lock. Turn it upside down (with the “pins” at the bottom of the keyway and the rekey hole to the left of the keyway.
If you look at the bottom of the cylinder, it will look like this:
You will need an SC1 Blank. The reset kit comes with a Kwikset SC1, but any SC1 blank will work.
Insert the blank fully. Be sure it is fully inserted.
This is your new friend, the SC1 SmartKey Reset Tool.
With the key blank inserted, place the reset tool on the core with the prongs on the left side, in the holes.
Hold the reset tool firmly on the core while you remove the key blank.
While holding the core and tool together, rotate the tool to the right on the core until it stops.
Remove the tool.
If you look at the front of the plug, you will notice that the keyway reset is off center.
Turn the plug in the housing until the change key hole is at the bottom of the housing (which is currently at the top of the picture due to how the tool is used).
If you look closely at the keyway to cylinder orientation, the keyway lines up with the flats on the sides of the core.
Now do the rekey procedure as above. Put the rekey tool in the hole.
Push it fully and firmly in all the way.

After:
Now put in the key fully and turn it to the removal position.
And the core with the lost or non-working key is now working!
Hope this helps some people out.
