T. James, double check the sensitivity on your shock sensor. Most alarms that randomly go off for no reason is usually due to the shocks sensor being too sensitive. Lower the sensitivity and you should be okay. The sensitivity should be located on the shock sensor itself. Hope this helps. Good luck.
My 2005 mercury montego car alarm goes off for no reason and I stop it with the alarm button on the key. It started in Dec. 2008 and now does it every few weeks and then stops and does it again. Anyone know what would stop this or fix it. Cleaned the hood switch and stopped for a week. Any information would be appreciated. Thanks.
