Usually the chime sound comes from a relay box in your dash. There are two possible ways of shutting it up. 1 Disconnect the relay box. In this first case make sure that the box doesn't control anything else, or you'll have to do the other way. 2 Locate the box, disconnect it, open it, cut the wire that goes to the speaker, close the box, and put it back where it belongs.
One probably cause is that the door is slightly ajar. Another is a faulty door switch ... if the contacts aren't closing properly, leaving the circuit open with the door shut securely, the door chime will sound.

To shut off the door chime on a 2004 Kia Optima, you can try the following steps: First, ensure all doors are closed properly, as the chime often sounds when doors are ajar. If the chime continues, locate the fuse box under the dashboard or in the engine compartment and remove the fuse related to the door chime or instrument cluster. Alternatively, consult your owner's manual for specific instructions or settings related to the chime.

I've had that happen in my 2002 mountaineer. what I've found is that if you spray the door latches with wd40 it will clean off the sensors and the door ajar light should go out. but make sure all the doors are shut.
Close the door.

The door ajar light might stay on in a Mercury Mountaineer if a door is not shut properly. Sometimes a door will seem like it is shut, but will not be shut enough to trip the light off. Check for dirt or other debris in the door latch for all doors.
Shut the door!

Oh, dude, the past tense of ajar is... wait for it... ajarred! Yeah, I know, mind-blowing stuff. It's like when you open a door and then you ajarred it shut. So simple, yet so confusing, right?
