SOURCE: Door locks don't work

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.

SOURCE: 2003 Hyundai Sonata Door Lock Problem

I had this problem. Through some research and asking some service personnel I found out it is a fairly easy fix. You will need to buy a new relay switch for the door locks. The dealer will/should know what you need. They are located (two of them, buy two and replace both) on the back side of the fuse box. It is not that easy to get back there. I had to lay on my back with my head up under the instrument panel. They are visible and can be removed if you take some time and be careful. Once I knew what I was looking at, it was easy to replace and the remote works like a charm. You can go to an auto supply, like Autozone, and they should have a schematic to show you where these relays are.

I have a 2005 sonata that the doors will automatically lock sometimes and not others. When we leave the car sometimes it will lock automatically and sometimes it won't. My wife has locked her key in the...


We had a similar problem with our 2002 Hyundai Sonata. It got to the point where it almost seemed possesed. Closing the door with the car still running could make the doors lock. Which was a problem. I simply pulled the fuse from the fuse panel under the dash board for the locks. The locks have to be manually operated now but at least we don't have to worry about "phantom locking".

2002 HYUNDAI SONATA. KEY FOBS WILL UNLOCK ALL


Replace the "lock" relay, found behind the fuse box. You have to stick your head where the gas pedal is, and look at the top end of the back of the fuse panel. There are 2 small square plastic boxes. Unplug them, spray them with electrical cleaning spray, and switch their spots. If everything works, there was some contact problem, if door will now lock but not unlock, one of the relays is bad. Part number "HMC DECO 95225 - 38300".

My 02 Sonata can be unlocked (all 4 doors) from the outside using the key in either the driver or passenger door, but will not lock. Any suggestions?


Yep... more information!.. same behavior when keyless remote is used?... IF SO, then you have a bad relay - door 'LOCK' relay.

Good Day 2002 Hyundai Sonata door lock issue. With remote or door switch, relay clicks but there are no functions. Where is the relay and what other problems could there be.


The door lock/unlock relays are under the dash in the I/P (Instrument Panel) junction box. since you 'hear' the relay CLICK, but nothing happens (no functions), seems to me you need a technician to diagnose/ troubleshoot the problem.. would you agree? If not, you could Go to www.hmaservice.com and register( Vehicle by VIN). Afterward, you have access to shop manuals, service bulletins, wiring diagrams, etc. about your vehicle.

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.

According to my tech, it is called a driver's door lock relay, but he was not sure the exact location.

Remote door locks


Hi,
Had the exact problem on my 02- Stick you hand under and pull out one of the relays where the clicking is.
Really tight under but I did it more by feel. I also went to a auto recycle place and picked up a relay from another sonata for 1 dollar, better than 30 dollars. Works like new. Take in the old one and match pins and numbers. There are two relays the same one for opening and one for closing . It is small and is hard to pull out. Good luck.
