Sliding door latch

The small handle on our Anderson sliding door broke off so we are looking for a lock replacement. I am not sure which lock I need, but there is an "A/W" on the front of it if that helps. In the pictures I posted each part next to the tape measure in case size helps in identifying the part. It would also have to match the same color as that is the color of the rest of the hardware throughout the house. Thank you so much for you help!
