Solution

A tuple is immutable, so you need to create new ones.
For example with a dict comprehension to create a new dict where each key will be the 1st and 3rd element of the old key.

{(k[0],k[2]):v for k,v in dict_1.items()}

{('ABD12-GOU14', 'ASS 4W LINE 4'): [4, 5],
 ('ABD13-GOU14', 'ASS 4W LINE 5'): [2, 5],
 ('ABD14-GOU14', 'ASS 4W LINE 6'): [3, 5]}
