I finally found out how to turn off that annoying door chime and here it goes!
First off let me say it doesn’t permanently shut it off but it’s a turn off while you’re using it.
All you have to do is push ignition button and the button on the door jam same time!
At first I thought I had to push the brake pedal and ignition button and button on door jam but later I realized no it’s just ignition and door jam.
When I say door jam button I mean door jam button. The black button that is depressed when you close you drivers side door. There’s a screw right below it but yiu don’t have to mess with uninstalling anything just press those two together and beep turns off until you start it again.
