Horn makes noise when car is locked/unlocked

[haux]

I put in a high mounted stop light today in addition to the rear spoiler LED stop light... just to see how it would look. Well, ever since then my car horn honks slightly when locking or unlocking the car. Unplugging the main connector for both stop lights doesn't make it go away. While putting the stuff in... I noticed the alarm light/button turned on and stayed on. Normally, when locking the car for example, the light flashes... in this case it was on permanently. This has happened before, and the remedy I've noticed is to push the light/button with the car running, and it goes back to normal. Well, I did that, but the car horn is still making this noise. Any ideas?

You can try to reset the system by turning the key to the "ON" position and pushing the button eight (8) times.
Might be more/less than 8, I don't remember, but the horn will honk and the button light flashes if done correctly.
I think there are other settings you can change by doing that, but I can't remember.

That's not your horn, its the tweeter.. the RS3000 security system

I couldn't find anything in that link about putting the alarm back to default settings. I tried disconnecting the battery... and it did no good.

I asked a guy at the dealership about it, and he wanted to charge me for a diagnostic. Douchebag. I've called them several years ago when I first couldn't figure out something with the alarm and the guy helped me over the phone. I guess it all depends who you get. Maybe I'll call another dealership tomorrow, and hopefully get someone with a clue.

Sounds like you have an aftermarket alarm? With a special "loud" horn when activated?

Because during lock/unlock, the OEM Fujitsu-Ten alarm chirps and/or flashes the turn signals. The Gen5 chirp is even quieter.

I believe the original owner purchased it already with the alarm. I don't know if it's an OEM alarm or one that may have been put in at the port... just like the electronic rear view mirror and alloy wheels.

However, it acts just like my dad's OEM alarm in his '96 Tundra. When locked, it chirps once, all the lights flash once except reverse and the LED brake light. The headlights also turn on for maybe 5, 6, or 7 seconds. When unlocked, it chirps twice, I believe those same lights flash twice, and the headlights turn on for the same duration. Sounds like OEM to me.

The horn noise it's making now is not normal. I don't know why it's doing it... and I'd like to make it stop.

After re-reading this, I'm unsure if you're suggesting that I have an aftermarket alarm or just saying that it now sounds like one.

In any case, yes it does now sound like one. Except it chirps too! Magical?

Bump.

The reason I'm not certain was because the Fujitsu-Ten alarm uses the chirper, not the horn, when locking/unlocking. Maybe it has an option to use the horn, I'm just not aware of that. Does it?

I have absolutely no idea! That's the thing. This horn noise is new. I'm confused as to why it's happening in the first place. I've also been unable to find any information about this Fujitsu-Ten thing.

Still haven't called the other dealership like I thought I might try. I should do that today.

Problem solved.

I found this booklet hidden inside of a planner in my glove box.
The procedure on page eight disabled the horn noise. Now it's back to the chirps only as it was.
