I don't know, but a lot of people (myself included) would love to have some sort of sound as confirmation! :lol: I hate trying to see the lights in bright sunlight or listen to the click of the locks to make sure the doors locked. Gonna be a bitch when my batteries start to die.
I have an '07 Taco with not a factory alarm but a dealer installed factory apporved alarm. Supposed Toyota Motor Co. has apporved the alarm, not sure what that exactly means. It's made by Karr. I was wondering if big dumps or anyone else has the same.
