Just brought a hyundai excel 4 door 1997 and i think that i have a problem with it shuting down with out any reason, get a 4444 fault code when i check with L-wire afterwards (no Fault), this keyring immobiliser has 2 buttons, button 1 turns off and on the immobiliser, but button 2 seems to do nothing, when either bottom is pressed the small led on the keyring lights up, i am wondering if it is after market or genuine immobiliser, there is a led light that lights up just below the dash on the right hand right when button 1 is pressed.
