Compatibility???

Thanks for posting. I took a look at the 82-306 handle with key; it does appear that it should work with the 82-261 handle set. It comes with a Kwikset key. The 82-306 can accommodate various hole locations, including the 3-15/16" hole locations you would need to match the hole locations in the 82-261. Take note when installing the 82-306 exterior handle the key cylinder tail end sticks out the back of the handle. You will need to drill a 9/16" hole into the door to accept the key cylinder. About the key that comes with the 82-216 handle set, it looks similar to a Y11 key blank which can be gotten at a hardware store or locksmith.
