This may sound stupid but I like the beep that it makes..lol.

Anyway, when I use the button on the door handle to lock it, it no longer makes that beep/chime noise. Also when I use the button on the key to lock it, the horn no longer sounds. And when I unlock the car the signals dont flash anymore. This all happened randomly last night and everything worked fine for the past year. Anyone have any ideas what may have caused this?? Thanks.

 

just hold the "lock" and "unlock" buttons at the same time for a few seconds, and you can turn the horn and beeps back on. you may have inadvertently done that same thing last night, turning the beeps off.

 

It worked! Thanks alot!
