Meta Car Alarm

its driving me crazy, even the smallest fireworks Set It Off help

I'm not familiar with it, mine has a black box under the hood, which is the main switch to turn it off in an emergency and it should also be a small screw to adjust the sensitivity (it could be covered by an eye not immediately visible).
Have you tried looking online for a manual for ita I found one for mine.
Sorry I can not be a great help, good luck

is that the car was sitting outside my house with the alarm to go all day!

Manafacturers / Travel dealers so I'm afraid
