Door locks don't work

The door locks on my 2002 Hyundai Sonata don't respond to the door switch or the remote when trying to lock the doors. The remote will unlock all doors but will not lock the doors. The door switch will not lock or unlock the doors. Someone suggested replacing the door lock relay. I cannot gain access to the door lock relay as it appears to be behind the fusebox under the lower left dash panel. Does anyone know how to remove the dash panel to access the relays or is there an easier way to replace the door lock relay?

    I have the same problem and have pulled the relay switch part # 95225-38100 plugged in behind the fuse box and am going to replace it and see if that fixes the problem.

Disassemble the paneling on left side ,under the steering wheel. Remove all screws and pull out the panel until you can you can reach behind it to remove the two Black Relays, on the side closest to Steering wheel. Remove the Relay covers, Clean the contacts with a 1/8 fine strip of 600 wet/dry sand paper. Only place the paper between the contacts, and pull out while holding slight pressure on the relay Armature. Turn over the sandpaper and repeat once again. Very gently press the TOP resting contact pad closer to the armature, to lessen the gap between the contact points, so the armature doesn't have to travel as far to reach the closed contact position. Repeat the above with the other2nd Relay. Replace the covers, reinstall the relays And test the Door locks prior to buttoning up the paneling. Note, a pair of long needle nosed pliers will help in removing the relays. Just Grip the relay and rock in Forward and Backward as you apply upward pressure.

You can get to the relay box without removing the under-dash. Get down on the driver's side where you see the hood release. Now, with your hand go forward toward the engine and up. Feel that? That's your relay block. Now that you know where this is, get comfortable (on your back) and remove the black relay which is the one one the upper part of the relay block. It should have a smaller white one next to it. I used my adjustable channel lock pliers to remove the relay. The part # 95225-38100 DECO.

Gott3 is right about not having to remove the under-dash. Just wanted to mention that it's a very tight fit in there, so be prepared to spend a while wiggling it until it finally gives (like 30 minutes to an hour).

Instead of wasting time and rolling around on the ground for 30 mins
to an hour just remove the panel work smarter not harder dont be lazy
it is only a couple of screws and it saves you from maybe breaking other things or pulling wires from some where you cant see

The drivers side cook lock does not lock or unlock using the remote. The other door do respond to the remote. What is the cause and solution?

Hi Charles

The drivers side door gets the most use
Check the actuator wiring coming through the door hinge
If it works from the key then the Power to the door is OK & the key switch is ok. Must be trigger wire from wireless device receiver!

Good Luck

I have a 2002 Hyundai Sonata. When I lock the door within the car or with the remote. They lock but it make a nasty noise when they are locking.

depending on which doors are 'making the nasty noise'... what you are hearing is/are the door 'LOCK/UNLOCK' actuators. They are AGING and if you choose, replace them.

My 2003 Hyundai Sonata Door locks will not lock using

I have exactly the same problem. Keyfob will unlock the doors, but will only arm the alarm once the doors have been locked manually. Central locking button on driver side door no longer works, but I hear the clicking sound you're referring to.
I took it to a mechanic, and he seemed pretty sure it was a bad master window / door lock switch. The price he quoted to replace it was $255 plus tax, and I could never bite the bullet and pay for the work, so I've just been living with the problem.
Have you solved your situation yet?

Hyundai 2002 sonata,,,, car has power locks.

You are correct in your assumption about a relay... there are two relays. One is for 'LOCKING' the other is for 'UN-LOCKING.' They are both labeled as "LOCK" relays (1 & 2). You can verify if a relay is bad by swapping one with the other. If the problem moves to 'unlocking' the doors, but will NOW LOCK - the relay is bad. If not, further troubleshooting is necessary.

Program remote control for mazda mpv 2002

Courtesy of: forums.mazdaworld.org

Try this, it works on several 2002 models:


Step 1: Open drivers door and leave open.

Step 2: Lock and unlock the drivers door using the power door lock switch on the door.

Step 3: Insert key into the ignition.

Step 4: Turn key to on position and return to off position. (IMPORTANT - use ON position NOT ACC position). Do this 3 times within 10 seconds. Leave key in the ignition.

Step 5: Open and close the drivers door 3 times. (Door should be left open after this step).

Step 6: ECU should respond by locking and unlocking the doors.

Step 7: Press any button on remote #1. ECU responds by locking and unlocking the car doors.

Step 8: Press any button on remote #2 (etc.) Each time the ECU will respond by locking & unlocking the doors.

Step 9: Remove the key from the ignition and the ECU will respond a final time with a series of door locks and unlocks. You're done
