shape key using 2 different object

[sex is scary]

idk how to formulate this properly so sorry in advance

i have 2 separate object, i want obj1 to have as shape key obj2
how can i do that?

obj2 is a copy of obj1 so same number of vertices, both have subdivision modifier

i was thinking copying the vertices position of obj2 and pasting it on obj1 but idk how to do that and there is probably something less janky and simple that can achieve the result

if object 2 has the shapekeys and object 1 doesn't, and they're both identical, why not just duplicate object 2 and replace the first one?

The 2 object are different, obj1 is the base and obj2 is the shrinked version, they aren't identical they just have same vertices

select the base object in object mode, then you can either press alt+d or in the object dropdown menu select "duplicate linked".
this will create a shared copy. all changes made in edit mode get mirrored, while changes in object mode can be set individually for each copy.

that doesn't help my problem tho? it just create a shortcut for objX but that it, the 2 objects are created already

ok find something that kinda botherly fixed the problem :
temporary deactivate obj2 subdivision to bettler see corner
activate "snap to" (shift tab) and select vertex
proceed to do shape key
fiddle around obj1 on obj2 until everything was correct
