    If it is the factory installed alarm the main control box has gone nuts. I have the same problem and just live with it due to the cost of the part which if I remember correctly is in the $400.00 plus range. And it can not be disabled because it will shut down the ignition.

    how old is the alarm?
    who did the install?
    what type of system is it?
    does it immediately go off when locked?
    are there any signs of disturbances? ie: look for cat prints listen for loud trucks or car mufflers

    have you got sensors inside the vehicle, if you have these are sometimes set off by a window left slightly open or air flowing the the air vents if they are slightly open. or a spider crawling inside the vehicle. hope this helps.

1998 Ford Taurus key in alarm-how to disable. Tried replacing switch but no luck. It runs the battery down. Have to disconnect battery when parked. HELP

Not the lock cylinder but the part it goes I to. Remove the plastic cover from around the steering column. There should be a single wire usually pink with a stripe ( want to say it's brown but might be wrong) . Often the plastic part of the plug breaks and basically it shorts to the surrounding metal. Your options are 1) replace the plug; 2) wrap with tape to prevent shorting out and 3) unplug and wrap up so it no longer functions and cannot short out.

Alarm problem

I had the same problem but it was because the Air Shocks were going bad and the truck was lowering and raising itself causing the alarm to trigger.

Alarm on my 2002 F250 started going off all of a sudden while parked and unlocked. the only way I could make it stop was disconnecting the batteries. what's wrong with my truck?

First, take the battery out of your key fob. All of them. Then hook the battery back up on the truck. If alarm doesn't go off, put battery in one fob. Check it out, all functions. Then check the other one. If alarm goes off when you hook truck battery back up, look for a shorted switch to whatever you alarm monitors and sets an immediate alarm when the switch is closed (or opened). If you still can't locate the reason for the alarm, consider replacing the alarm system, but not before you come back here and tell us what happened.

Alarm goes off for no reason. Message center shows hood is "ajar

Hi There isn`t much that can be done here, I would suggest you take the car to the dealership if the alarm is original, if it is after market then take it to any alarm shop, it needs to be reconfigured.
Good luck.

My security alarm goes off intermittingly without any apparent cause, usually 4-5 hours after I have parked it (and locked it up) for the evening. I end up having to open a door to stop the alarm and then...

When I bought my 2001 Jimmy, it did the same thing. Searched the "net" and found the solution. Open all the doors and clean the light switch buttons. Sometimes they get dirt in them. This worked for me. I've never had this problem again.

1999 car alarm goes off when the car is locked.

Not a solution, but details about the same problem with my car: I have a 99 Lincoln Continental and have noticed correlations between certain conditions and the frequency of the car alarm going off.

When it is hotter outside, the alarm goes off more frequently than when it is colder.

The more of a slant the car is parked on, the more often the alarm goes off. My boyfriend's driveway is on an incline and any time I park my car there, the alarm will go off every 30 seconds. If I move the car to the level street, it doesn't go off at all. This has been noticed on other slanted places I've attempted to park as well.
