After reading about the alarm system in this 97 850, I wanted to see how it works. Unlocked door, sat inside the car, closed the door, and did not put in the key. After about a minute the doors locked. Cool. I could unlock them by hand. So I then put in the key and tried to crank the vehicle, and it DEAD. All dash lights lit up when trying to crank by clearly the vehicle was disabled. Dont know exactly when the emergency flashers started, but they did, however the horn never sounded. Should the horn sound as well? If so, could the previous owner have disconnected it, and where? Your input most appreciated. Thanks.
