The clicker will not lock or unlock the front

Usually a break in wiring going from door into pillar in a rubber sleeve!!

On some models you set the theft system when you lock the doors and when you manually use the key to open the door the alarms will go off. To solve this use the key fob and see if you still have the problem. I don't think you will see the problem when you use the key fob to open the doors.

You may need a new Fob . Don't know where you live but most auto part stores have a device to check signal strenght .

Sounds like the key fob is going bad and needs replaced.

Could be your driver door lock mechanism that is going bad , since the other door are working, it cannot be the fob. I would try to change the driver side door latch mechanism.

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.

possible bad button on key fob.unlock button good lock button bad .get a new clicker you can program it yourself ....put key in ignition turn back and forth 10 times while holding the unlock button on remote.that should work

unlock the door then press the lock button on remote and hold down for 20/30 secs.manual does say hold button.....

Insert key into door barrel or ignition lock and turn key, whilst doing this press the unlock/lock button, the led on the dash should flash to indicate this has initialised the key to the car, then remove key and test operation of remote. If this fails then a new remote plus coding to the car by your dealership is needed
