Need New Striker and lever latch?

A quick learner from San Diego says:

I have an existing sliding door handle that I want to replace with a keyed handle. The serial number on the door handle is stamped "DR05-1505". I plan to replace it with product "82-081".

Do I need to purchase a new lever latch and striker or will the existing parts work with the DR05-1505?

Thank you.

I'm not sure if your hardware is compatible with our 82-081. Your mortise looks like it will be, but your old handle set is a different style and I'm not certain that our set will install the same way. Can you confirm the distance between the two installation holes, center-to-center? Can you also show me a picture of your thumb lever out of the door? I want to be sure it has the same shape as the one that comes with the 82-081.

The distance between the two installation holes looks like it's between 4-7/8" and 4-15/16".

Here are some photos of the thumb lever out of the door. Thanks for the help.

Looking over the style of this thumb lever, and your old mortise, I believe the 82-081 should work on your door. It should be fully compatible with your hole spacing and mortise.
