When I activate or deactivate the alarm with the keyless entry remote my horn honks (beeps). Does the same thing if I use the keypad. It is really annoying and I don't think my neighbors like it either. Any way of making it so the alarm dosen't honk? On my wife's 02 explorer, it only honks if you press it a second time. This is driving me NUTS!!!!!!

 

It isn't a "chirp"? Your horn blows? That would suck. Mine "chirps". Maybe the dealer could do something?

 

Yeah it's the horn. The factory installed alarms seem to use the horns. When you press the lock door and arm system on my wifes explorere twice it honks (beeps) the horn once.

 

My 05 doesn't honk unless you press lock twice.

 

my mustang chirps too. The horn honk is waaay to loud, so I can see how the neighbors are getting annoyed. I think that ford miswired something. have them fix it, but be careful, they tried to charge me $200+ to adjust the sensitivity of the alarm they installed!

 

I think all the new Fords with keyless entry are like that. Once locks all the doors press the button again and the horn gives a quick beep. My wifes 05 explorer and my 04 FX4 does too. She does the same thing pressing the button twice thinking they didn't lock the first time. She had a 04 neon (piece of crap) it honked every time you locked the doors ( one press of the button).

 

I think some where in the owners man. I saw that you could disable the horn when locking/setting the alarm.

 

The first thing you need to know is the 04/05 F150 does not have a factory installed alarm.
The horn sounds on the second push of the button . There are two modes to this.If the horn sounds one time all is ok with locks.
If it sounds two times there is a door open and all is not ok.
This info is in the owners manual.

Mike's right....I doubt you have the alarm, rather just the keyless entry. That little blinking red light doesn't mean you have an alarm.

Try it....don't "disarm" your truck....use the key and open the door...nothing right?

I think the alarms from Ford have CodeAlarm written on the keypad.

theres also a inconspicuous black horn under the hood that says on a blue sticker " ford security" or something like that. So all the new trucks etc honk the horn instead of chirping??

 

This is a topic which I am too lazy to investigate. I think that the alarm system is actually a anti theft system? Your vehicle goes into a electronic hybernation after the doors are locked. The key pad disables itself after several failed attemps to access the vehicle. The system also looks for the coded key, or it wont start. I don't think there are any sirens that go off when broken in to. On my truck I use the fob to say "lock" the truck then says "ok locked" by a fast blinck of its headlamps. I think the
second button push is just a verbal confirmation that says "Yes I did lock up!" Either way the system is activated.

 

No. I definately have alarm. If I don't disarm, and unlock door w/ key and open door, horn starts honking like crazy. I have alarm AND keyless entry.

 

That's just it. My 05 f150 honks like your neon did. Press it once, it honks. Press it twice, it honks. Unlock, lock, you name it, it honks. I can't hit my button, or use my keypad ( on door ) without it honking.

 

I think you have a dealer installed alarm. Do you have a little black box below the stearing column that when locked has a blue blinking light? If so you should have a owners manual in with the truck manual. I had the same annoying horn honk and I turned mine off by following these steps: Turn the ignition key on then off; within 10 seconds of turning the key off press and release the valet button (on the bottom of the black box on the dash below the stearing column) three times. Any time you disconnect your battery you will have to re-do this because it will reset. Hope this helps.

 

Sweet! I will give it a try. Thank you. Yes it is a flashing blue light with a box down there under steering column. Will let you know how it turns out!
