Broken Anderson sliding door lock mechanism

Thanks for reaching out! The Andersen hardware in your door can be replaced with the 82-037 Andersen Reachout Deadlock Assembly, which is compatible with the 82-043 Andersen Tribeca Thumb Latch.

Since it appears the lock is on the left handed side of the door (from the outside looking in), I believe you'll need the 82-316 LH Gliding Door Keyed Lock. Be sure to double check that there is an "L" on the inside of the lock, as shown below.
