I want to know when I press the remote control unlock/lock button, how can I make the alarm system have a flash light/"bebe" sound in the same time? I bought a 1999 Nissan Maxima, but when I press the button the system just have the flash light without the sond, so I want to know how can I make both. Also, is it have a chip in the key?
