When you start the car or turn the key to ignition horn will blow for about 1 minute

30 minute reset turn key on ten minutes security light will go off turn off back on three times it ctanks

Have you tried putting the key into the ignition switch and starting the car ?

In some vehicles, you can place key into driver door cylinder and manually lock / unlock which may turn horn off.

It happens a lot for the Tiburon apparently....what you have to do is put the key in the ignition whilst the horn is going nuts, turn the key to the "on" position and wait a minute or so for the horn to stop blowing. Then press the "unlock" button on the fob until you see the turn signals flash. try turning the key over and see if it will start up. If it doesn't, try again, same thing only turn the key all the way off and try starting as normal again. I can't remember if it's the "unlock" or "lock" button you're supposed to press, but one of them does it. Test it while in the car and see if it locks when you hit lock on the fob.....oh, and also make sure all the doors are shut while you are doing this. It recalibrates the fob to the car's computer and resets your security system and keyless entry.

Check ignition switch, and starter solenoid for functionality. Also, just because the horn blows, doesn't mean the battery holds a good enough load to crank the starter. Check to see if battery voltage drops when key is turned.

did you removed the steering you might have grounded the wire for the horn , it works on a ground system i would check the wire again and make sure it's now shorted

Sounds like you need to reset your alarm kill switch, which should be located near the driverside kick panels. GL.

1. Turn the ignition to ON, then wait 10 minutes for the next step in the programming sequence.
2. After the 10 minutes has elapsed, the car horn will chirp once. Turn the ignition switch to the OFF position within 5 minutes after the horn has sounded, then to the ON position within 5 seconds after switching it OFF.
3. Leave the key to the ON position for 10 minutes . After the 10 minutes has elapsed, the car horn will chirp twice. Turn the ignition switch to the OFF position within 5 minutes after the horn has sounded, then to the ON position within 5 seconds after switching it OFF.
4. Leave the key to the ON position for 10 minutes . After the 10 minutes has elapsed, the car horn will chirp 3 times.
5. Verify that the security indicator in the instrument cluster has stopped flashing and attempt to start the vehicle.
6. Turn the ignition to OFF and remove the key from the ignition switch.
7. Move approximately 3 meters (10 ft) away from the vehicle and test the transmitter functions to validate that the transmitter has been programmed successfully.

YOUR WIRELESS CONTROL MODULE(SENTRY KEY MODULE)MAY BE ELECTRICALLY LOCKED UP..THERE IS A SERVICE BULLETIN FROM CHRYSLER..YOU CAN REMOVE IOD FUSE IN FUSEBLOCK(UNDERHOOD BEHIND AIR CLEANER..IGNITION OFF DRAW(IOD)THIS WILL RESET WIRELESS CONTROL MODULE AND VEHICLE SHOULD START AND LOCKS RESPOND AGAIN..IF IT DOES,THE WCM WILL HAVE TO BE REPLACED AND THIS NEEDS TO BE DONE BY DEALER

I think your horn relay is making contact from behind your horn buttons on your steering wheel. Usually as time creeps up the insulation that is placed on the positive lead for the horn gets worn out from constant horn action. If it is worn down the horn is touching a ground and completing the circuit and thus making the horn sound. I would start with that first before getting more technical. Let me know. Gabe

It sounds like it has been deactivated so we are going to reactivate the auto lock.

The numbers I will be saying will have to do with getting this to work so:
you will need to put the key in to the ignition switch.

1= is back to listen to the radio
2= is to get key out
3= is just before you start
4= is for starting your car

When we do this 1 and 4 will not be used
Do this and we will hope that it works like it should:

1: Turn the ignition with you key up to on( don't start)

2: Press the power door lock control 3 times

3: now turn the key back once (to off position)

4: Press the power door unlock control 3 times

5: ok turn the ignition back up 1 time. (The horn should chirp)

6: Then press the unlock control, then press the lock control, again (horn will chirp 1's) If auto lock
was activated.

7: Turn the ignition back 1's, Then the horn should chirp once to confirm the procedure was completed.
