Lock replacement

Hey there, thanks for posting. It looks like you have the Andersen 82-056 along with the 82-058 bracket for the 3 panel patio door set. Unfortunately, I'm not sure if your key lock with the housing is still available. That's a pretty old design and we don't sell anything that may replace it.

One idea is to maybe use a key cylinder like our 82-310 to see if this could work replace your old key lock, as long as you can reuse the housing. Otherwise you will need to contact a local Andersen dealer to see if they still sell this old style lock.
