Key for patio door lock

Question

Would it be possible to obtain a replacement key for this KK lock or do I need to replace the entire part?

Thank you,

This looks like a handle set for a storm door. But you said that this is for a patio door. Can you confirm? We sell a few different storm door locks that are similar to yours, but I can't say for sure if they can work. It would ultimately depend on how their dimensions compare to yours.

Start by looking at our 40-089, 40-123, or even our 40-129. Look these over and see if any of them match the dimensions of your existing key lock.
