When I first purchased the vehicle the oem car alarm worked. The green security light would light up & the doors would lock & horn would honk when I arm it. Now the green security light doesn't come on but when I arm it it still honks & the lights still flash. When armed I tried opening the doors & the alarm did not go off. Any ideas? Bad sensor, brain or bad wires? Any help will be appreciated. Thanks.

 

bump I'm still trying to figure this out.
