Just bought house, trying to replace locks

A home owner from Eldersburg, MD says:
Inswing patio door. The only logo I can find says, "The Aluminum Door." We have tried the generic replacement from Home Depot, but it was too small. Help!

Here is what I can read from the bottom right corner of the glass:

BS (or B5, can't tell) 6206A

I believe the lock and handle set you are looking for is our 82-400 . Take a look and compare it to yours to be sure they match.
A professional from California says:
If the handle works, and you are just concerned with new keys, you might also want to look at 40-089 or 40-123 . The whole handle is probably the better choice, but the cylinder is another option.
