First of all when have you replaced the battery in your key remote? and also the buttons on the key pad can stick and this is not the main computer for the car it is in the antitheft system and in most cases it is the sensor in the door or the trunk lid itself the computer could be showing it is open and what you can do when you park the car at night watch out the window and see how long it takes for dome light to go off if it takes a long time it is the sensor in the security system

it sounds like the anti-theft module needs to be reset so it won`t go off when it shouldn`t.the module thinks the car is being stollen as it went into anti-theft mode and needs to be reset.usually the light for this problem(gross vacume leak) will reset on its own when the computer goes through its test procedure for the evap system and detects no fault.

Antitheft alarm on our 2001 mercury sable goes off on its own


Get a new car! JK - my 2002 Sable does the same thing. It can be 5 times a day then not for a month, or 2-3 times a day for a week straight. It happens in different locations and different weather and different times of the day. To my knowledge has never done it in my garage at home.
I have not called a dealer. Has anybody ever found the real problem? Could it be in the remote itself? I tried leaving it unlocked at work, but yesterday it went off just as I was reaching toward the door handle.

Dead Battery!!


there should be a plugin under your passenger seat to unplug for the alarm. If by chance you don't you will have to trace the wires and unplug it.

Instrument Cluster lights do not go on, emergency lights steady- Sable 2002


Has anyone figured this problem out? Our 2002 Sable just started this as well...instrument cluster lights out, turn/hazard lights on when the headlight switch is turned on. This has the auto on/off switch with fog lights. This is happening in the auto and manual on mode. Any solutions would be appreciated.<br />
