I have a 2004 Civic 4-door. All the door locks work great. I have two keyfobs and neither will work. I've put new batteries in them and tried to reprogram them several times ...following the instructions PERFECTLY (I've read every procedure on the internet) ...but they will not work.

Can anyone tell me what the problem might be? Is this a common problem?

NOT all came equipped with keyless.

EX, LX, DX, DXVP, GX, what you got?

Joe-NC

It is an LX.

I bought it used. 200k miles of long distance highway miles. I can't imagine a car looking newer with this many miles. No one had even removed the rear seatbelts from their factory shipped position. It was a fleet car and was maintained by the book.

It came with 2 keyfobs and I can't get them to work.

Instructions on Page 5.


My service manager can't follow these, but somehow I can. Even with my reading comprehension problem. LOL


Does the red light on each fob light up when you push a button? (battery check) Make it so.

Power locks all work properly --- other than the fobs?

The doors will not lock or unlock with the transmitter if the ignition key is in the ignition switch.

If any door is open, you cannot lock the door with the transmitter.





Get in, shut all of the doors, hood, and trunk.
(When it says "ignition ON", that does NOT mean start the engine. Just the key on and dash warning lights all lit up.)
I always use the LOCK button on the remote because it is big and easy to hit consistently. I'm all thumbs most days.



Turn the ignition to ON, push the LOCK button on one transmitter. Turn ignition OFF.
ON, lock, off.
ON, lock, off.
ON, lock, and the power locks should cycle. Did they? (I just keep doing this until the locks cycle, I can't even count to 4.)

NOW you push one button on each transmitter, including the one you already had in your hand. Locks should cycle each time the system accepts a new transmitter. Did they?

Turn the ignition off, remove the key. Check remotes.



So what step did or didn't happen right?


Ok, fuses: #10, dash fusebox, 7.5amp.
#9, engine compartment fusebox, 10amp.

Then do wiring/voltage checks right at the keyless control unit.
Then maybe start in with multiplex unit troubleshooting. Anything else not working that the MICU controls? Warning beeper works?

Umm, I doubt it. The cleanup crews roll them up neatly and tuck them like that.
Seems like seatbelts usually come already buckled up on brand new cars on all but the drivers seat.
