Broken sliding door lock

A quick learner from New York says:
The switch that you turn on my patio door lock broke off. I would like to replace it with a new switch. I would also like to replace the key lock on the outside, because I did not get the key when we bought this house. I think these are Anderson sliding doors because the lock has an AW printed on it. I would like to know what parts I need to order. If this helps, the lock operates with a little hook inside. Thank you.

Thanks for posting. Yes, this is Andersen hardware. For the thumb latch, see the 82-043. For the key lock, it looks like you have a door that, from the outside, opens from left to right. If so, see our 82-316 Left Handed Andersen Key Lock. Let me know if you have further questions.

If I want to change the locking mechanism on the inside, can you let me know which part to buy? Thank you.

Yes, if you mean the thumb latch on the inside of the door, see the 82-043. Let me know if you needed anything else.

I meant the locking mechanism that goes inside the frame. Do you know what part that would be?

This is likely the 82-037, but without seeing a photo there's a chance it's a different lockset. If this does not appear right, please send photos of your lockset and I'll try and find something better.
