I have the factory alarm, when I lock or unlock it, the horn isnt working. If I press the scream button you can hear it, someone know about this problem?

 

Lol, what is the scream button??

 

our cars can scream? does it sound like a little girl scream? LoL But seriously if its not the scion security I dont think it honks when you unlock or lock. Mine didnt anyway. I dont know about scion security system.

 

yeah, every alarm is dif. some won't honk at all, others only when you lock, and some when you lock and unlock. but if your works normal and panic works, than you got nothing to worry about.

arm your car, wait 15 seconds and manually unlock your door and open it. if your alarm goes off, then you're good to go.

 

thanks
