Actually on my 2003 Hyundai Sonata gls i had the same problem...there is a manufactuer alarm that should set off when u put the key in and turn.. do that one more time(BUT makng sure alrm goes off then do it again) then don't take the key out turn offthen set it in the acc. position in the ignition after the alarm goes off then wait about 5 to 10 min and turn on by then it should have reprogramed and kick on..the third time is when you should be waiting for the programming to be down...its very very important that you do the programming on the third time...because the computers are built in the car and not built like most other American made cars....
To activate the security alarm on a Hyundai Sonata, ensure all doors are closed and locked. Use the key fob to lock the doors; the alarm will be activated automatically within a few seconds. If you prefer, you can also manually lock the doors using the door lock switch inside the car, which will trigger the alarm system. To deactivate the alarm, simply unlock the doors using the key fob or the key.
