2003 Sonata with original 2003 Hyundai alarm system. Can crooks access the alarm system by copying fob sent signals?
I have a 2003 Hyundai with the original theft alarm system. It has recently been claimed that the security of the system can be violated by thieves equipped with electronic copiers that detect the signals sent out by the fob transmitter, and then send out the same signals to the car while the owner is away from the car, thus unlocking it. Is this correct? If so, what can be done to outwit the thieves and prevent them from doing this?
