Hello!

I would like to buy a lock for this handle of my patio door. Can you tell me what to choose?

Thanks!

Hello, Geneviève! Did you only need an exterior key lock? If so, see our 82-315. I believe this will work for your outer handle, as long as it's flat. Be sure to also watch our video below for installation instructions.
