The back sliding doors will not lock with the remote or the switch on the drivers door, why?

Asked by Nov 22, 2014 at 10:23 PM about the 2012 Kia Sedona EX

Question type: Maintenance & Repair

I click the lock button on the remote and the front doors lock.  The sliding doors will not.  
The sliding doors will not lock with the button on the drivers door.  You have to manually
reach in the back and lock the doors each time.  They will not lock either.

Simply take it to a Kia dealership ...

The dealer will charge you about $600 for this part and if you order it online from the website I gave you it is only $148.30. Copy and past the link below into your URL address and it will take you straight to the part website for KIA. Find another place or your husband to put the new part in the dealership will charge way too much! search_str=81450-4D513

Hey Annette, I too am having the same problem. I researched your link and show that the part is called a CONTROLLER and it is selling for $132.59. Am I correct that this is the part that will fix the back sliding doors that will not lock except manually?

I have the same issue with the passenger side sliding door and the rear hatch door. Neither of them will lock and the back door doesn't have a manual lock like the sliding door. Any idea what I should do or should I follow the advice to just buy the part and fix it myself?

I just had the controller installed but now my passenger door will not lock. Please help. All of the doors will locks except this one.

I had the same issue with the back door and recently bought the part on ebay _trksid=p2060353.m1438.l2649&ssPageName=STRK%3AMEBI DX%3AIT It was $102 and a local mechanic changed the part in my house for $80. The local KIA dealer wanted to charge me $700 for parts and labor. They overcharge incredibly!!! Get the part and find a decent mechanic to change it
