sliding door lock set replacement

Question

Hi
I am trying to help a client of mine find the right lock set replacement for her sliding door.
The interior part is a handle with the locking mechanism attached, 2 rotating metal pieces.
The exterior is a pretty deep lock cylinder housing, as the sliding door is super thin, so the lock cylinder must be covered fully by the lock cylinder housing and be flush with the door.
The mounting screws and holes must be the same dimensions as drilling new holes in the door is not allowed. The client did not provide the dimensions, so hopefully the images that are attached will help determine what lock set would work.
Thanks

Hello,

the 82-063 would be our best replacement option for the old-style HiLite assembly shown in your photos. The determining factor would be how the dimensions below compare to yours, paying close attention to the 3-7/8" hole spacing. Unforutnately, we are not able to supply a version of this handle set with a keyed exterior handle, which I believe may no longer be available. Take a look and see what you think.
