Had a Bulldog remote start/alarm installed 4-months ago. Was very pleased w/ it till the "Security" light came on and once would'nt start after a 4-midnight shift. The techy installed a relay in place of the "diodes" that sense the resistance built-in to the factory "kill switch." No problems since. ***ut be sure to Lock and Unlock w/ the remote. If you Lock with the door panel switch AND the remote Lock button, when you open the door of the vehicle by Unlocking w/ remote your horn will sound, waking the neighbors. ***ut insert the key into the door lock and Lock/Unlock it.
Hopes this helps.
