I've had two occasions in the last few days where my theft alarm has started sounding, without an apparent cause.

The first time, I was inside the house, had the keys in my pocket, so I assumed that somehow I had unintentionally hit the panic button.

But yesterday, I was not at home and my wife was outside planting things near the truck. Her keys were inside. The alarm started sounding, no one else was around and she had to go inside to get the keys and shut it off.

Have anyone else experienced this?

After the alarm went off 4 times this past Saturday, I disabled the alarm by disconnecting the hood sensor (under the latch is a plastic connector, somewhat hidden, but easily reachable).

Took to dealer today, and after an hour or so of diagnosis, they have ordered a replacement Smart Entry control unit.

Hi everyone, I have a 2017 RTL-E and the alarm just started to go off by itself. Happen about 3 times in the last 4 hours. Checked all the doors, tailgate, and truck and they are all close. Hoping someone can point me to the right directions. Is there a way what the alarm is all about? Thanks.

Depending on where you live AND what your friends/neighbor think is funny, is it possible that someone is messing with you? Otherwise I think you could have a loose door switch that is setting it off. Do you manually lock it or is it set to auto-lock?

Where was your key fob during this period of time?

 

[tinman93]

There have been a few occasions when I have had my keys in my pocket (on a different vehicle) and managed to se the alarm off by sitting in a way that the button has pressed. I would see where the fob is when this is happening.

Or maybe a family member is messing with you

2017 Ridgeline, 41,000 miles . . .My alarm system started going off unexpected today . . .first time I was shopping and thought someone may have messed with the car. After I got home, it went off again while parked in the garage. The dash lights flash on and off and makes a clicking noise.

Any thoughts?

Take it somewhere and have them do a load test on the battery (pull the stuff covering it off at the house).

Yes and my first thought would be battery connections. Make sure they are clean and secure. If Honda or anyone else worked on it previously, they may have disconnected the battery cables and maybe didn't get them back on tight enough.

2017-ridgeline 30k miles. I started having the same problem for two weeks now
it happened 6 times now. Took it to the dealer twice, no trouble found...
I hope someone can HELP....

My 2018 has 39K miles and the dashboard lights keep going on and off when the truck is off. The alarm goes off for no reason as well. I thought it might be the battery in the key fab but after changing it, the problem still occurs. Glad I'm not the only one with this issue but this has been driving me crazy.

I was having the same problem in my 2017 Ridgeline. The dealer determined it was due to a faulty push button start.

From work order:
Customer states alarm goes off randomly.
Found that "IG" to be trigger for security system.
Push Button Start was tripping alarm system intermittently.
Had to replace push button start for engine.


The following were replaced by the dealer:

Battery 31500-TZ3-100M
Switch Assembly 35881-TG7-702
Control Unit 38320-T6Z-A21

 

[flepper]

First time they said it was the master switch for the windows. This time they said there are bad codes coming from the fuse box. Waiting on the part. We'll see.

Had the same problem. Problem was intermittent and I was out of town so friend had towed to dealer. Dealer kept for several days and did not notice the problem (intermittent) until I was about to pick up the truck five days later. They called to tell me the alarm had gone off, then advised that the fix was a new control unit which handles the keyless access system (and perhaps other things). See attached receipt for part number and cost, which was over $800 with tax. Because of mileage, truck is out of warranty.

NOTE: See note by mechanic that each key must be reprogrammed with the new unit. The service rep didn't bother to advise me of this, so they programmed only the key I brought in and I will now have to return for them to program my other two keys (I have a spare). If you need this fix, be sure to bring in both (or all) of your keys.

This is the second major repair of electronics on the truck. They also had to replace the audio unit (#52691) because the navigation system would not update. That repair however was covered by Honda, even though the truck is out of warranty. Not sure why one of these fixes was covered and the other not.

Having the same issue on ~41k 2017 model as well. Mine goes off 4-5x/day, I took it to dealership and on the 2nd take-in, they pinpointed the problem to the keyless entry as well (they thought but had to get further confirmation during a weekday from Honda?). Anyhow, I took my truck home, don't want to take it back to the shop for a $600-$800 "fix" & just haven't locked my truck since...
Does anyone know the best path to just disable the alarm altogether? I'd rather take my chances than spend hundreds of dollars...

I'm having same issue too, it's 4:00 am alarm keeps going off even when I've unlocked it. After two trips to an Alarm shop, thought it was a motion sensor it's still acting up. Truck is possessed, interior lights going on, dash indicator flashing, I can hear clicking as something is trying to engage?? Had to unhook the battery to get it to stop. I'll try dealership and keep you posted.

See my post a couple above yours which includes a copy of the repair receipt. The clicking sound was also present in my case. Since the repair, I have not had the problem.

Thank you for this forum! I thought my 2017 Ridgeline (38K miles) was possessed by the Decepticons, dash lights flashing, clicking noises and then the car alarm going off indiscriminately. I too had to disconnect the battery to stop the truck from alarming. Thanks LifeSaver1 for the copy of your repair invoice, ouch! I have an appointment this coming Monday at the dealer and I will bring a copy of it. It's amazing to me that Honda has not announced a recall for this problem after a year of his happening to us Ridgeline fans and that the dealer network doesn't seem to share solutions to this problem across the country.

Hello .. my 2017 Ridgeline just started having this issue but it is coincidentally right after I had my back passenger window replaced and inside door trim panel (my truck was broken into by them smashing the window). Point is, I called the service company who did the repair asking if while they were inside my door, could they have not connected something back write and he said 'absolutely not' .. no way we could have messed something up. So, question #1 - could they have messed with something and did not connect 'things' back correctly? and #2 - when the alarm goes off, i can stop it by hitting the unlock button on my FOB (do not have to unhook batter) ... could this be caused by something else than what has been posted here already ?

Appreciate any help
