Answer 1

Insert keyframes to all shapekey values

for active object:

import bpy

def add_all_keyframe(obj, attr="value", frame=1):
    if obj.type != 'MESH': return

    blocks = obj.data.shape_keys.key_blocks
    if not blocks: return

    for k in blocks:
        k.keyframe_insert(attr, frame=frame)

add_all_keyframe(bpy.context.object)
bpy.context.scene.frame_set(bpy.context.scene.frame_current) #update ui

for selected object:

import bpy

def add_all_keyframe(obj, attr="value", frame=1):
    if obj.type != 'MESH': return

    blocks = obj.data.shape_keys.key_blocks
    if not blocks: return

    for k in blocks:
        k.keyframe_insert(attr, frame=frame)

for obj in bpy.context.selected_objects:
    add_all_keyframe(obj)
bpy.context.scene.frame_set(bpy.context.scene.frame_current) #update ui
