I have a 2004 Hyunday Sonata, it came w/ a factory keyless entry system, the one with the four buttons. When the car was off and I exited the car, I was able to press the lock the doors and activate the alarm system, at this time I would here a beep coming from the car, veryfing the instruction to activate the system was performed. Now I can still activate the system but the beeping is gone, is there a way to reset the keyless entry beeper to make that noise again.
Thanks
