See other post I would ask them to check the sensors. Something is wrong for it to be going off when parked. Is it doing it all the time? If it is I would suspect that you have a drain somewhere and the alarm is picking it up. Most alarms have a "voltage" meter so if someone gets in your, say through an open window, and starts it. The voltage drops, hence causing the alarm to go off. Or it could be a wiring issue or a sensor for the alarm has gone bad. I would take it to a alarm shop and have them look at it. Best of luck and I hope this helps.

Could also be a sensitivity setting that needs to be tuned down. I have seen firsthand where local fireworks shows set off an alarm on cars a mile or so away every time a loud boom is heard. I have even parked next to cars which went off when I shut my car door, or walked past them. If there is a sensitivity setting you may want to have it dialed back.

i have the same exact problem with my 92 sc400. i'm hoping to get it checked out today. pls post ur solution if prob is solved and i will do the same. thnx
