Assistance with Product Selection

A quick learner says:
I am trying to replace my sliding door lock to a keyed lock and I need assistance selecting the right product. The current lock does not have a Mortise; it looks by a hook and can only be opened on the inside. I've attached some pictures for reference.

My goal is to be able to unlock the door from outside. Please let me know if you can recommend a product that would solve my request.

Hello,

Your handle set reminds me of the 82-009A with a clamp-style latch depending on how the specifications below compare to yours. This handle set does not come with an external key lock but it can be used with the 82-306 keyed exterior pull. Take a look and thanks for posting!

Hello,

so if the specifications match up, the interior will have the 82-009A with a clamp-style latch and the exterior will have the 82-306 keyed exterior pull. What mortise will I need to for both products?

Thanks,
Anissa

To clarify my follow up question, I'm trying ti figure out if I need to buy a separate mortise or does the 82-306 keyed exterior pull automatically came with a mortise?

Thanks,

These handles actually do not use a separate mortise lock since the 82-009A uses a clap-style latch attached to the internal handle as shown below. The latch is what would engage with the frame to lock the door, which appears to be how your original hardware was designed.
