So this happened like a week ago. You know how when you press "LOCK" twice on your remote the car will beep. Well now when I press twice it doesnt beep anymore and the lights dont blink to tell me that the car is locked. It does lock the doors but it just doesnt beeep anymore nor do the lights flash.

Why is this happening?

 

Your trunk is open.

 

^That our your back doors are not shut all the way.

 

I tried both the trunk and doors and it wasn't the solution. Any other ideas? Maybe some kind of sensor in the doors is screwed up?

 

hood

 

Ok so i tried all the doors, the hood, trunk and nothing. When I press the panic button only the lights flash and the horn doesnt sound. When I press lock twice it locks the doors but the lights dont flash and the horn doesnt sound. Maybe a fuse to the horn?

 

Besides a 15A horn fuse, there is also a relay that needs to be energized for the horns to sound.
You can try swapping it with another similar relay.
I believe the relay below it is the FOG relay and should be the same.
Look at the model numbers and verify they match.

 

Update?

 

Well to be frank, this is really stupid of me, but I decided to see if my horn works and it doesnt LOL. So I opened the fuse box and I pulled the relay that says "HORN" Im not sure how to test to see if its burnt or not.

So im gonna bring it to the dealer tomorrow and get another. Ill see if that works.

 

Please let us know. I am having a similar problem.

 

I will let you know. I have been lazy to take the car to the dealer but I took an apointment for tuesday. Ill keep you posted.

 

If your horn doesn't work, how do you let the rest of the world know they are f'n idiot drivers! That horn has saved me from getting run over countless times! Not to mention you won't pass a safety test for your inspection.

Horns are important...get it fixed! Fuses are really easy to replace, if you've already pulled it out, you've done the hardest part.

Good luck!

 

Or, if you need a new horn. . . .

Sounds like some Italian Freight train. Though I've never heard one in person and I'm too cheap to get one myself.

 

I know man! I want to use my horn so many times. Some idiots still dont know you can turn right on red lights in montreal now. F**** lol and people who cut you off deserve to be honked at. It sucks not having a horn.



UPDATE: So I went to the dealer. They put in a new fuse and it didn't work. They said they have to check the wiring for a diagnosis and it could take time. Since its not under warranty im not gonna spend few hundred dollars to fix a horn. Maybe it will magically start working again?

 

 

This happened to me. I figured out that if you hold both the locking & unlocking button down on the fob at the same time, in the vicinity of your car, the beep is turned off. I reversed this process & now it beeps again. Try it on yours.

 

Woow ... I have to say thank you man. I brought my car back from a body shop and after like 3 or so days, I ran into this issue. I don't know how it it started. Car would lock but doesn't beeb to confirm the lock as it used to do. I checked all the doors/trunk/hood and didn't work. The panic button button was working fine though. As you said, I tried this morning holding down the open and close button at once on the remote and it worked perfect. Thank you !

 

Thank you so much!
I was trying to figure out why my key fobs were not beeping when I locked the car.
Thank goodness my horn beeps so I didn’t have the problem the other person had.
Simple fix and I am so happy!

 

Hi I tried holding the 2 buttons down and nothing happened. Is there anything else that I could try to get the horn to honk when locking my car doors. my horn works but not when I lock my doors and the lights don't blink when setting the alarm.. if anyone has any advice i would greatly appreciate it

 

Um, this is a Mazda RX-8 forum. Probably not a lot of 2004 Honda Accord knowledge here.
