Patio Sliding Glass Door Keyless Locking Mechanism

Hello,

We'd be happy to look into this for you but we would need to see photos of your original hardware, along with written-out dimensions, to determine if we carry anything that might work as a replacement. Thank you! 

Thanks for getting back to us. I can't be sure since you photos primarily show the back of the handles but what I can see reminds me of the 82-002 shown below. This handle set uses an upward-facing locking hook that installs in an opening like the space you are pointing to in your photos. Take a look and compare the specifications shown in our images to confirm if this is a match to your assembly.

It looks like the sweep latch shown in our product image is missing from your handle since I see no other way that you would be able to engage the locking hook. As long as the dimensions and hook orientation match up to yours, this would be our best replacement option.
