Hi there! I'm afraid the labels on your door don't tell us what hardware your door uses. We would need to see photos of the parts you're looking to replace to compare to our inventory. |

Thanks for these photos! These are older Andersen parts but our more modern parts should work perfectly well. Start by looking at our 82-037 mortise and 82-043 thumb latch. I feel confident that these are what you want but look them over and see what you think.

I have these exact parts on my Anderson patio door. If you use the key the latch cones up and pulls the door tight against the jamb. But using the thumb latch the lock latch does not pull tight, leaving a gap and the door not secured. Going nuts trying to figure it out.

I'm not sure why you're having trouble locking your door from the inside of the house. The thumb turn locking "tail" actually goes into the back of the key cylinder and kind of acts as one locking unit. If yours locks fine from the outside with the key, then maybe you need to replace the inside thumb turn or possibly replace the inside mortise lock. Also make sure to check the operation of the door itself. Maybe the rollers need to be adjusted so that the door lines up plumb with the jamb. Lastly, check that the lock is adjusted properly so that it lines up with the keeper. |
