Honda Car Alarm Goes Off After Battery Replacement - How to Fix

The battery died in a 2015 Honda Accord with a wireless key fob and remote engine start. When I installed the new battery, the car alarm immediately turns on. I show how to use the key within the key fob to make the car alarm turn off when you're installing a new battery.

My BIL left his Honda CRV at my home when they were away over Christmas. We had really cold weather (-35C) and the vehicle wouldn't start(it was also plugged in as it has a block heater). Today my neighbour came over and put the trickle charger on it, and has soon as he attached the second clamp the horn starting going off. I phoned and spoke to an Advisor at Honda and she explained that it was the car 'waking up' and to sit inside and press the brake. Before I went back outside to do this I decided to search KZbin and came across your video. Pressing the brake did not work -- BUT sticking the valet key in the door lock and locking and unlocking it did the trick!!! Thank you so much! Honda could take a few lessons from you!

I only thought of the cartoon character little bill

[@tomjones9490]

Thank you. I already had a neighbor yelling at me through the window after my alarm went off for the Third time. Worked perfectly. Much appreciated.

[@PhysiqueFuel]

I truly feel car alarms are more trouble than help

[@abag6005]

Dude I was embarrassed by neighbours till I searched on KZbin and found this video and it worked ✅ thanks man

[@Hyderagean]

Embarrassed in front of your neighbors* Your neighbors did not embarrass you by laughing and pointing, I hope.

[@TjSpoonManJacques]

LISTEN TO ME: THIS IS THE ONLY VIDEO THAT WORKS! THANK YOU BROTHER AND MUCH LOVE FROM NEW ORLEANS BECAUSE WE TRIED EVERYTHING

[@ballhawk387]

Much thanks, right to the point, saved me a literal headache. The only other thing I can add is to have some earplugs handy.

[@UrbanAnywhere]

Wow you saved me a big headache. My brother went overseas and left his car with me. The battery was flat and I was replacing the battery. I couldn't figure out how to make the horn stop. Lifesaver. I had to lock and unlock the door to get it to stop but would have never thought of doing that. Worked on a Honda 2022 Accord.

[@whitetrashandhellbound6905]

Same issue on 2012 Accord EXL... I have been hitting the "Panic" button on the Fob for like 20 minutes lol obviously did not work. Never thought of doing this method, life saver 🤟🇨🇦

[@shdwhntr-df6uw]

Great video, super easy fix... worked on my MDX after replacing battery... VERY SIMPLE. Thanks for making this so easy.

[@Mogipbob]

I am going to try this today for my 2017 Accord. The alarm is SO loud. Thanks for the tip!

[@nikcosymcdonald4435]

You helped me a lot. My car wouldn’t shut up after I changed the battery and my neighbor already hated noise.

[@LibertyHand]

Thanks, Vincent! My daughter called with hers going off after a battery swap today. You had the answer.

[@dogbounty6399]

you saved the day. I pulled my horn fuse and your technique still worked.

[@KD-ou9bm]

Is it the horn fuse or alarm fuse or are they the same?

[@sallagudi4964]

Very helpful video that fixed the problem! I just had the same issue with a 2009 Honda Civic after replacing the battery. Thanks Vincent!

[@sunrisedino9066]

Dude, you may have just saved my job lol. Thank you! It worked for me.

[@getdusty1]

Thanks, Vincent. It worked on my LOUD Honda Pilot horn. Worked like a charm. The unlock button did not work but the key in the door did work. Thanks again. I owe you a coffee.

[@teachtv9188]

This is awesome. Just had the same issue with CR-V and it worked perfectly. Thank you

[@887fantini]

Thank you. I think I'm going to keep the key in the door then connect the battery. Love your neighbor.

God bless you my man!!!! I spent about 3 hours trying to fix it. Thank you 🙏

Thanks so much, alarm started just blowing up in middle of parking lot luckily had a Wrench and unplugged the battery and found your vid thank you

I have a mdx too did it get rid of it completely ? Anything specific u did for it to stop ?

[@786qad]

Car alarm went off. Thanks so much

[@mikethetrader]

worked like a charm simple to do stick key in door turn to the right and back to vertical thxs

[@mePatricia]

This was greatly appreciated!!!

[@outdrs10]

Added tip: Pull the horn fuse first, then only the headlights flash

[@TheShodan92]

My problem is the same thing except the key does not turn in the door lock this the car alarm horn continues. But thankyou for this video.

[@m.p.3460]

[@michaellopez-us9nh]

Really worked wow lmao on a 2002 Honda odyssey you’re a life saver (well for my neighbors jeje”

[@brianchicoine621]

Thanks bro this video was really helpful

[@JayD-cx7he]

LOL..just pull out the Horn fuse and relay. Tighten the negative battery cable, start the car and go plug the horn fuse back inn.

[@tomandjoandinnel4981]

This is the method I used. However, I do not think you need to do anything with the Relay. Just pull the Horn Fuse. Then when you put the battery terminal on you see the lights flashing without any noise. You can then take your time turning the key to stop the alarm. Once the alarm has stopped you can put the Horn fuse back in. The Horn fuse is relatively easy to pull but you will need needle-nose pliers and review the location on another youtube video.

[@enriquepatron7553]

@@tomandjoandinnel4981 how did you get the alarm lights to turn off? same thing with my car. I took out the horn fuse but the alarm lights flash and won’t turn off. (The key fob doesn’t work)

Brilliant. It worked for me (Toyota)

[@cbarrera20]

Thanks bro I was driving crazy with this F horn

[@aeonjoey3d]

Dang it, I have a 2008 and this isn’t working, turning the key only makes the windows and sunroof open and the alarm keeps blaring, pressing unlock on the driver door nothing, key in ignition doesn’t do anything either - it is electronically killing the ignition - both key fobs, buttons “work” normally while the alarm is blaring but they don’t disarm it. I’m wearing earplugs in my garage at night trying to do anything about this because I need to go to work in the morning and I’m screwed nothing is working. :(

[@aeonjoey3d]

Update. Okay it was the car’s battery being low causing this. I charged it with an external charger and it stopped going off after reconnecting with a full charge.

[@Amha395]

Thanks same boat as you were. In my neighborhood only people that watch not that will actually do anything if someone is actually trying to steal your car. This video helped a lot shutting off the alarm. Key fob is dead needs new battery.

[@marc5101]

I have this problem in my 2008 Nissan Altima but nothing’s working unfortunately. I have the alarm unplugged now so no more blaring, but the car still flashes when I’m idle

[@jeffyoutube8648]

I check my car to connect the battery because I will use it later then alarm goes on so I unplug it and search fix. My question is after your method no more alarm after starting the car on/off?

[@Killa_t]

Wait do you do it while it’s locked or unlocked? and then put the key in and turn it?

[@jasoncanas8783]

Thank you. Brother 🎉🎉

My problem is that it keeps going off randomly after I stop it like you shown on the video. Any idea or tips? T.T
