I just installed my new stereo on my car and I tried to arm my car with the alarm, and it dint work, its not reading the antenna or something, cause the control works fine. I need help fast I live in apartments and I dont want my **** gone when I wake up. I did a lot of things to the car to prevent it from going anywhere, but there is still lots of things that you can take off on the spot. What do you guys think is wrong

 

check for wires you may have knocked loose. like the antenna wire, a ground, ect.

the stereo and alarm should not be related unless you have them grounded in the same spot or something.
