Good question. Your outside handle set has a centered key plug, while your thumb lever is offset down. That means you will not be able to pop a a key cylinder in your handle. That said, you will need a new handle set, like our 82-044, with a 82-315 key lock. Take a look at the video below for more details.

Hi there,

I'm trying to do exactly what's being done above. I have a question before I go ahead and purchase. The Truth 45434 outside pull sits flush with the door. In the case of your handle, it looks like the shafts designed to receive the screws protrude. In my case the door frame doesn't leave much room to accept those protrusions. Can you tell me how deep they are on your handle?

Cheers,

John

The screw posts on the 82-044 do stick out a little, yes. At 9/32" diameter, they're designed to fit inside the holes in the door. That said, I've seen some older doors whose holes were too narrow to accommodate this size. Whenever I encounter that, I just take a rat tail file and widen them a hair. It doesn't usually take much, just enough to get them to fit. 

That said, most of the time I find that the holes in a door are wide enough to accept the screw posts. It's rarely an issue, but when it is the solution is simple.

The people who were looking to add a lock on their 45434, what did you guys finally did? Cause I have the same handles here and was looking for the same thing, putting a lock on one of my door. THX!
