Ok, so today i locked my car and for some reason i decided to pull drivers door handle and the car opened! But the alarm went on i had to press open on the key fob to shut the alarm off it does not work on any other door just the drivers door, Need to fix this because last night my alarm went off in the night and it was my car and i saw the drivers pin was up like someone opened my door. I know it also could be alarm siren battery being bad

 

how do i know if its on or not? my car automatic locks over certain speed (15 kmh) i think

 

ah did i answer your question without knowing?
