It could be the horn relay, a defective fuse or a shorted wiring. Need to check the wiring first, then the fuse and lastly the horn relay.
You push the button to stop it
On 2003 Tibron when you set the alarm off do the following, while the horn is sounding turn key to ACC, roll the driver window down and wait for horn to stop then wait 30 seconds and start the car.
First, disconnect the battery to stop the horrid noise! The switch for the horn is in the center of the steering wheel - it may be tricky to get to this switch with an air bag unit in the steering wheel, something best left to a professional repair facility.
That depends on the computer type, but try going into the settings and changing the locking settings.

horn will not stop honking on my 2004 pontica grand am
I would locate the fuse in the fuse box and remove the fuse, that's not fixing the problem but it will stop the automatic locking.
yes horn is not working
Pull the fuse for the horn.
Turn the volume down a bit.
