Having problems with your Hyundai Motor 2002 Sonata ?
My 2002 sonata alarm wont shut off and my keyless wont stop it and the car also wont start with the key either
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.).
