Sliding Glass Door Handle

A home owner from North Carolina says:
My Mother lost the keys to my house while dog sitting. I have replaced all the locks except the sliding glass door. Is there a way to order a replacement? Thank you.

Sure, take a look at our 82-310 key cylinder. I think this should work with your patio door handle set and mortise lock.
