where is the central locking relay located?

This doesn't sound like a relay, but more like a latch assembly that is not releasing. The clicking is the attempt of the latch assembly to release itself but it is not successful. You may have a problem with your Body Control Module, which controls the electronic locks, or you may need a replacement latch assembly. Further diagnosis would be possible using a DRB scanner to see if the BCM is storing any codes related to your problem.

Trying to figure out why my door on a 2014 Kia Sorento doesn't want to lock by pressing the buttons I have to manual lock it all the fuses are good cuz I checked them

Trying to figure out why my doors on a 2014 Kia Sorento doesn't want to lock by pressing the buttons are on the keypad I have to manual lock it. I checked all the fuses and all the fuses are good

@Bromp07 did you ever figure it out or got it fixed? I am having the same problem.

Sounds to me like yall both are having problems with the Body Control Module... $500-$600 fix diy

i have same problem took it into dealer and its the bcm part number 95400-1U031 but you might need to flash the key fob.

Mine has something to do with the gear shift not making contact in the park position. Try moving forward or backward and hitting the unlock button. Not sure on the fix yet.

could it be that the fuse block needs replacing..cost??? I'm having same problem

I was having similar intermittent door lock issues on my 2014 Kia Sorento then yesterday I woke to find my battery dead! Got a jump and proceeded to Auto Zone to get a new battery ... low and behold my door locks are working flawlessly so far. Could it be when your battery is beginning to fail that the door locks start to fail? Is it a safeguard to delegate power from unnecessary accessories to starting the engine? Just a thought folks !

I can unlock my car with the faab but not lock them. That's with both door and faab. Is this a fuse problem or internal?

Mary, did you find the issue? Mine will not manually lock with the fob, wil not lock manually by hitting the lock button or even with putting the key in the lock but i can lock it by remote start. Car unlocks just fine. Any ideas?

Will not lock does it have to do with the setting on the steering wheel that have lock and unlock status
