I do what i find on internet and hold the unlock and lock button and the lights flash and the horn beeps but once i lock again pushing the lock button it will not beep, is this normal?

1. Put the key in the ignition and turn it to on.
2. Press the Unlock button three times.
3. Turn the ignition off.
4. Press the Unlock button three more times.
5. Turn the ignition back to on.
6. The horn should beep once. This tells you that you're now in programming mode.
7. Press the Unlock button, then press Lock again. The horn will beep once to tell you that Auto Lock was deactivated. It will beep twice if you're reactivating the system

There are many ways, I'm not sure which one will work on your car. I answered the two ways. I hope it works.

1. Open the driver's door and put the shifter in Park
2. Turn the ignition to On (II).
3. Press and hold the unlock side of the master lock switch for five seconds until you hear two clicks.
4. Within five seconds, turn the ignition to the Lock position.

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.

You might need to take it in to a dealer to have the fob synched to the car. Is this in Canada , USA or some other country? Some counties have an immobilizer that can become confused if they lose power completley ... like from changing the battery.

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.

hold lock and unlock buttons on your key fob simultaneously until lights flash and horn beeps.this should do it.

Setting can be accesed through the radio to change options. Follor the owners manual.

There will be 2 chirps indicating the the audible is off. To turn the chirp back on, repeat the process and the system will chirp one time when it is back on.

Programming: 4 codes may be programmed.
Sit in driver's seat and unlock all doors. Open and close the driver's door
Turn the ignition key from LOCK to ON position 10 times within 15 seconds. Be sure to stop at both lock and on. The horn will HONK once to indicate transmitter programming mode is activated. Leave key in LOCK position and don't remove it from ignition.
You now have 45 seconds to complete the programming as below.
Open and close driver's door again.
Push either lock or unlock button on the remote you want to program. The horn will honk 2 times when successful.
To continue and program other remotes at the same time: open and close the driver's door and push lock or unlock on the remote. The driver's door must be opened and closed between each remote you want to program.
Done programming? remove the key from the ignition and the horn will honk 3 times.
DELETE old codes? Reprogram 4 times, it will overwrite old codes.
Alarm Security System: optional on all models. When locked there is one chirp (can be turned off, see above), the turn signals will flash and the red 'security' light will start to flash once every 2 seconds except for STi which flashes twice every 2 seconds.
There will be 5 chirps if a door, hood, and trunk or gate is not fully closed
You can also arm the system by using the power lock button on the driver or passenger door as you get out of the car and then closing the door behind you.
Disarm the system: push unlock for 2 seconds
Lost remote, alarm activated? When you can't use a remote to turn off the system: open the door with a key or try to start the car and the horn will start to honk. Turn the key on-off 3 times within 5 seconds and the alarm will go off and you can start the car. It's simple!

Open and drivers door, leave it open. Turn ignition key from LOCK to ON 2 times and then leave in LOCK position.
Tripped code: 1 security light flash: a door has been opened, 3 flashes when the impact sensor was triggered, 4 flashes when the ignition was messed with or battery disconnected

Most likely your alarm system needs reset. When you use the button to turn the alarm on and off the horn beeps and lights flash. Horn beep when switch turned on, makes sense would be in the alarm system with all you've told.

Press and hold for 2 seconds the LOCK AND UNLOCK buttons on your "keyless entry" keypad. The hazard lights will then blink 3 times and the horn will sound once- you are now good to go.;

The title of you problem mentions the horn but the actual problem mentions the flashers? Which is it? You can turn the 'horn beep' feature on and off by simultaneously holding the lock and unlock buttons down on the remote for about 3 seconds or more. When the horn feature is turned on you will hear the horn, and when it turns off you will only see the lights flash.
