Disable car alarm 2009 Mazda 6 V6

45

Asked by Dennis Oct 16, 2018 at 12:11 AM about the 2009 Mazda MAZDA6 s Grand Touring

Question type: Maintenance & Repair

I took my car to get diagnosed because the alarm was
going off and waking me up constantly. They said it was
the driver side rear door actuator but they told me the repair
would be $270 which is RIDICULOUS. if I get that one fixed
what's going to stop the other three doors from having the
same thing happen to them later?! Especially with this
being a common problem with this vehicle. paying $270! I'd
rather just not have a car alarm. How do I disable the
alarm? Right now I just pulled the horn fuse out until I find a
better solution.

I have the same problem with a 2009 mazda6, they said it was the lock actuators also. They wouldn't replace under warranty as they said the got wet, go figure water is designed to run thru the door and out the bottom of the door. Replaced both rear actuators, very easy to do, but the alarm still goes off.

Did you solve the problem Devin? If yes, mind to share how? I'm running into the exact same problem and would rather disable the alarm system than paying a large amount to (temporarily) fix it. Thanks!

I have a 2010 mazda 6 GT Same problem also. I have paid over $600 to “fix” this issue replacing the rear door sensors and there is zero remorse or ownership of the issue help to solve this problem from the dealership. This has been going on with my vehicle for years but it has been getting worse and worse. For a temporary solution you can pull the horn fuse until it can get resolved. Due to the progression of occurrence Could be buildup of oxidation somewhere. I noticed that all my fuses have built up oxidation on the metal tabs. Ive cleaned them all and applied electrical contact oxidation protection deoxit. Hasn’t fixed it though. Im going to start checking all the ground points in the car. It could be the security module going bad somehow too, so ill be looking for that and try and have a good look at it.

I have the same problem. The service team looked into the compute and there had been about 20 combined alarms on the passenger side from and both rear doors. So about $1,000 to repair. For now they recommend leaving the car unlocked. They said they would look into a way to disable the alarm function. I’ll let you know what they come back with.

I have a 2008 mazda 6 and the alarm goes off at least 3 times an hour. I've been keeping it unlocked as much as I can to prevent this, but it's not practical to leave your car unlocked everywhere you go! My alarm has been going off since i bought the car 2nd hand but the alarm had been going off increasingly with the heat of the summer. I havent yet tried any methods but have seen plenty of videos on ways others have solved the issue. If I unplug the sounder in the trunk of my mazda will it stop the alarm? Or are the alarm and my horn connected?

Anyone experiencing an issue with the battery going dead if you let the car sit for a few days? I noticed that the alarm issue is temporarily resolved after I would get a new battery. However I have never been able to figure out what is causing the drain on the battery. I assumed it was the door modules but i think they are symptomatic of a low voltage battery drain issue. Anyone solve this yet somehow?

Hi, I have the same problem with my 2010 mazda 6 bought second hand 6 years ago. First the dealer told me it was the driver's door latch that was defective (200$) which was replaced and alarm still going off. The they said it was passenger's door (another 200). Still going off. The, they said it was the back, I refused to pay anymore but the alarm still goes off. I noticed also that the car battery goes low even if it is a new battery. Any solution? It seems that I am not the only one with this problem

Same deal here, car alarm (2009 Mazda 6) going off like crazy. Took it to the shop 2 weeks ago, they diagnosed a bad door sensor (passenger side), charged me $650 including an oil change to replace it. Today it has gone off like 3x in an hour, so I just pulled the fuse for the car horn. I haven't had any battery problems, but given how often it seems to go off, im not surprised if the battery will get low given how little I drive it during quarantine.

I had pulled the fuse to stop the horn from going off. But when driving the horn is needed and one time another car bumped my car on the driver side and may have warn the other driver if my horn was working. So I bought an on/off switch, rated 20A. And 100 ft, 16 gauge wire, rated 20A and 200 degrees C. Hooked up the wire to the 2 horns behind the passenger fog lights to the switch. Now I can turn off the horn when I’m parked and turn on when I’m driving.
