I would PRIMARILY like to replace the brass colored INTERIOR hardware with more modern white or stainless steel colored handle and latch in order to fit in with redecorating.
The locking mechanism still works from the inside, but on the outside although the key turns in the lock, it does nothing to lock or unlock the door (it just spins). I would consider replacing everything depending on price, since we don?t really lock/unlock the slider from the outside. My main concern is the color on the inside and then price.
I have identified potential replacement parts as the Andersen Interior Pull Handle 5 1/2" #88-013 in white and the Andersen Tribeca Thumb Latch Replacement #82-043 in white, but am not sure if this latch will work with my interior lockset. It looks like the screws on both are spaced correctly. The brass latch I currently have looks a lot like your item Andersen thumb latch lock #82-241.
Could you please make some recommendations about what I should do for two cases:
1) Only replace the interior handle and matching latch with a white or stainless steel color
or
2) Replace everything. Please note, the exterior is on the oceanfront and gets a lot of wear from the elements.
Also, the last photo is of a brass colored piece that I don?t know what it is for. Is it necessary? Can it be easily removed, replaced with white or stainless steel color, or painted over?
