My 2008 Kia Rio is a base model and I have tried to manually lock the doors and use the remote to open it but it didn't work? When I use the remote to lock the door the horn doesn't beep and the light don't go off?
Do you
have the same problem?

Are you able to lock it with the remote?

Does manually locking the doors works the power locking system?

There may be a fault in the Alarm system or Body Control Module, BCM.
I am providing you with its set operation functions and what requirements must be met for everything to work and then what to expect to see when it is working right.
Diagrams of the locations of all components and anything else necassary.
The first thing to do is to have the trouble codes checked and replace the battery in the Remote Key fob. Advance Auto and Auto Zone will pull the trouble codes for free. This will tell you if one of the components has failed.
If no codes are present. There are some diagnostic suggestions. However the other thing to do is check connections to componets for corrosion, loose terminals or any problems that would keep signal from reaching it.
From there the grounds for the components would need to be checked.

The chart shows what you need to do.

I would suspect a faulty door lock switch and would suggest testing those first.

You need to perform testings to diagnose the cause and I would suggest starting with checking the door lock switches.

Door lock switches in this instance means the door lock actuator switch, which is inside the door panel. You need to test if the switches are signalling the BCM that the door lock is being opened or closed.

How do I get the passenger side door open to repair the locking mechanism when it is shut and I am unable to open it? The door locked and I have tried replacing the fuse for the central locking but it is still locked. Please can you advise on the best course of action?

I can not get the door panel off without trashing it and I really do not want to do that. I have tried to use the fob and the key but it is locked and I do not know what to do or how to fix it. Do I have to remove all the mouldings to get to the door panel screws on the bottom of the panel? Also, if I do manage to get the panel off, how will I be able to remove the locking mechanism from the door if it is locked?
