If you want, there are two options you can consider. You could just punch or drill out the circular punch in the outside handle and install our 82-310 cylinder, or you can replace the entire exterior handle with our 82-306. Let me know what you think!
A home owner says:
I would want the whole handle replaced. Do you know for sure if this fits in the old handles spot?

I can't guarantee it, but it's a popular handle and can work on a wide variety of doors. The only way to know for sure, however, is if you compare the dimensions we show to your own hardware.
