Locks will not fully open or close when using either interior buttons or keypad buttons. It is not localized to 1 door. It happens to all 4 doors/locks. Sometimes the locks will work fine for about 2-3 presses of the lock/unlock button. Other times they do not budge at all.
Check the central locking control unit ground connections.

I tried looking around without removing to much. Cant really see alot. But I did try messing with the keypad and interior lock/unlock button. 1) I have to hit unlock twice on keypad to unlock all doors, it seems that after unlocking and locking multiple times I can tell that as soon as I hit unlock the first time of round 3-4 of unlocking door that the drivers door lock only half opens. Then pressing a second time all the other doors only half unlock. 2) with the interior I presses lock/unlock and after about 3-4 all simultaneously inly unlock halfway. Occasionally I have to press unlock multiple times to get it to register I hit it. I can only compare it to a low battery where the lights dim, they have minimal power and arent functioning fully.

You are correct, symptoms indicates a low battery similarity apart from a poor ground.
The central locking system is linked to the body control module and repeated locking/unlocking can cause resistance buildup resulting in poor actuator operations.

Will it give out completely or will it maintain the weakening. Cause I dont really wanna rip out my lower console and then still not fix it and have to take it to a shop anyways. If it will maintain and not completely stop then I leave it be and get it to a shop at a later time. But if it going to fail shortly I might as well just take to a shop cause I been scouring the internet for a picture or guide for fixing it/ understanding what I looking for.

It will definitely get worse. This is a rare symptom and most likely you are not going to get any additional information. If you have a scan tool it might help you to track down the cause.

Scan tool? As in a code reader for the port under the steering wheel? And would this be covered by the Suzuki warranty?
