Ok so my sister has a scion XB and I have a friend with a TC and friends with Toyotas and they all beep to indicate the doors being locked on their car kinda like the old horn honk to indicate that all the doors are closed and locked and a double meant that one or more of the doors were open, my question is my iq doesn't do anything to let you know the doors are locked I have to check and what's the purpose of having keyless lock if I have to check does anyone else know if this is a feature that isn't on the iq or if maybe mine is defective and just doesn't work? Does anyone else's iq make a noise when locked???
