Please i really need help, last week my car started a fresh madness, i didnt drive it for like 4 days and when i wanted to go out, the car wont unlock when i press the key fob... i dont have a manual key on the key fob to use open it manually cus i bought this car with one key and there was no manual key on it, so that night i went outside and pressed the unlock botton several times while standing near the car, then i noticed the dashboard light was on.... but UNLOCK light on the exterior didnt flash, so i went closer and found the door was already open, i locked it back and the next day when i was going out, it opened at once but the lights on side mirror and tail-lights didnt flash .... i drove around for hours and returned home. Now, for another 3 days i didnt drive, but when i was going out again yesterday, the car wont unlock, i did what i did the last time but the car doors still wont unlock at all.
MY QUESTION IS which battery do i need to change??? the key batteries??? the auxiliary battery???? the main battery in the hood???? im very lost!!! please can anyone advice?

Replace all of them. These are old cars now.

For the starters replace the battery of the key FOB. If you cannot open the doors you have no way to get to the other batteries either.

And then get a new key with the mechanical key in it...

but i was told if the auxilary battery is weak i would get warnings on the dashboard... should i replace it even though i didnt get any warnings on the dashboard?

I did exactly just that but it still didnt open, i have resolved the problem anyway, the problem was from the second battery in the boot not the main battery in the hood, i bought a new one and its all working fine now
