I cannot figure out why my aftermarket alarm goes off in the middle of the night all the time, never goes off during daylight hours but all the time at night.

 

is it every single night? once a week? maybe someone's messing with the car, or a large truck is driving by. i assume its the shock sensor being tripped but does your remote tell you on the fob what sensor triggered the alarm? maybe you should stay up one night and wait for it to go off lol

 

i am sitting here now and it goes off twice or more a night every night. My car is parked in my grass between my neighbor's truck and my other car.

 

How sensitive is your shock sensor set? My freinds cat jumped up on my trunk and set it off.
We were out wondering what the heck hapened untill i saw the cat do it lol
