Answers :

When the alarm is activated, there is an Anti-Theft device (Starter Kill Relay) which prevents anyone from starting the engine using the key (about 5 minutes). If you place the key in the ignition and turn the key to the "RUN" position, wait 5 minutes (approx), the engine should then be able to start. If not, the problem may be the ETACS (Electronic Time & Alarm Control System) module. If it does start, the problem may simply be that the battery in the keyless remote is weak/dead, or the remote needs to be programmed again for that vehicle. Only the remote can 'DEACTIVATE' the alarm. Best solution, take/tow the vehicle into a Hyundai Service Center (dealership), pay the diagnostic fee. They will tell you EXACTLY what the problem is and what's needed to fix it (parts, labor, tax, time-frame, etc.).
