sometimes it is due to a weak battery.
Owners manual, or the service department
voltage drops on a weak battery can cause the alarm to trip. Whenever power is interrupted, even for a short time, the alarm will trigger. Sometimes not right away, but usually after the first drive after the power failure.
Don't. many try to to do that to install aftermarket alarms but since that is part of ECU programming many have never ending problems as a result. Add on to it if you need more or add a lojack. If you need to reset, an auto locksmith can do it easily.
my alarm goes off at random times. i had the alarm module changed for $700 and it still goes off. come home from work at 4 and it goes off at 10. before the alarm module was changed it went off at 12, 2 and 4 in the morning.
I've had that happen in my 2002 mountaineer. what I've found is that if you spray the door latches with wd40 it will clean off the sensors and the door ajar light should go out. but make sure all the doors are shut.

to reset the alarm system for a Mercury Sable when the alarm is causing the car not to start, place the key in the ignition. Turn the key only about halfway and leave it in this spot for 10 minutes before trying to start the car.
