Remote door locks

2002 Hyundai Sonata Reote
locks will not open.
I have been told that the remote open and close relays may be bad.
I can hear the clicking under the dash but find it almost impossible to reach them.
How do I remove them to replace these relays.

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.

I have a 2003 Sonata with the lock locking problem similar. I cannot even feel a relay let alone see it. I can cetainly hear it clickin behind the fuse box. Guess I'll just deal with manually locking every door everytime I need to lock the car. Not paying some shop $50 just to look at it. Maybe I'll just trade off the car.

How to Program Keyless Entry Remotes in a Hyundai Sonata By Christian Killian, eHow Contributor
20Found This Helpful The keyless entry system in your Hyundai Sonata is part of the factory alarm system. If you have to replace a lost or damaged remote, reprogramming will be necessary. The remote is important because not only does it lock and unlock the doors, it also arms and disarms that factory alarm when you open or close your car doors. New remotes are available from any Hyundai dealer. While they will program it for you, you can do it yourself and save a programming fee.

Step 1: Locate the fuse panel under the dash on the driver's side of the car. Just below it is the control module for the factory alarm system. Open the cover on the alarm system control module and locate the memory switch inside.
(Kleophaus Livingston/Demand Media) Step 2: Verify that the switch is in the "Off" position; if it is not, switch it to the "Off" position. This is important for the system to understand what you want it to do when you move to the programming mode.

Step 3: Insert the key into the ignition of your Sonata and turn the key to the "On" position. Wait for 60 seconds, then move the memory switch inside the control module to "Set."
(Kleophaus Livingston/Demand Media) Step 4: Depress and hold the "Lock" button on your remote for one full minute. This allows the remote and the control module to communicate and sync. Release the "Lock" button and turn the memory switch in the control module back to the "Off" position.
(Kleophaus Livingston/Demand Media) Step 5: Turn the ignition switch to the "Off" position and test the remote by pressing the "Lock" or "Unlock" button, verifying that the doors do lock or unlock.

POWER DOOR LOCK RELAYS


Dear fellow Elantranians,
I am an original owner of a 2002 Elantra (w/anti-theft module/ETACS), and have wrestled with the same problem for months: remote will unlock, but not lock doors.
The answer to the problem, at least in my case, was a door lock relay (Part #95250-2D000) located behind the center dash, to the right and below the radio and heater/AC controls (removal and replacement reasonably easy). A simple removal of one bolt and a wire connector, and the little devil is exorcised. It's been working without a hitch for more than two weeks, and expect it to continue for eleven years as the original relay did. I purchased this relay from a local salvage yard for $14.00, but a Hyundai dealership (jimellishyundaiparts.com), will sell it to you for $36.00.
Respectfully,
Lucky Elantanian

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 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.
