Horn sounds when remote locking used

Pull the horn fuse or relay, that should stop it. Then later in the day, replace.

Does the horn sound when you press it on the steering wheel if not check for a blown fuse to horn and then if ok see if you have power to horn and then if that is ok run a wire from the battery to the horn and see if it honks.

I have a 09 kia spectra, The only time the horn will honk. is when I lock the doors with the remote. Unlocking just makes the lights flash! God-Bless! and hope this helps you out.

Try resetting your remote device by holding it near the front drivers side and press and hold the emergency button until the horn blows once. See if that does the trick.......

This is a tough one, it sounds like the alarm is arming itself when you lock the door, the alarm system is arming , there is a way i think to cancel out the horn chrip, the only other thing is the door lock is bad or the alarm module is going bad. Did the horn always chrip or beep before and do you know if the alarm works?

If there is connectivity to the indicators then there is output from the remote control unit and the fault can be due to failure of the horn unit. You can remove the horn and use a 12 volt DC to test and if there is no sound the horn needs to be replaced. If not you can use a link from the line to the indicator unit to be connected with a diode- to avoid reverse polarity and to isolate the circuit to the horn

holdboth the lock and unlosk buttons on your remote simultaneously for about five seconds until the lights flash and horn chirps.that should do it.if not i believe these models used a separate horn for security system.possibly fuse for this horn is bad or the horn itself is bad.to see if this horn works lower drivers window.stand outside vehicle and lock doors with remote.wait about a minute and reach in window and MANUALLY unlock and open door(do not use power door lock button)this should cause the system to activate...horn should beep and headlamps should flash.if horn beeps try my first suggestion.if it doesnt beep and just the head lamps flash check fuses and horn for security system.

Press the lock button once to lock then press and hold to beep the horn. Kind of have to press twice.

try honking the horn normally with horn button <key must be on> if horn works it is in the programing for comfort and convieniance system if no honk it's just the horn or wiring to horn.
