Chrysler Repair: 2002 Caravan horn lights flash for no reason when parked, push button door locks, power locks

Question
Several times in the last month the lights start flashing and horn blaring on our 2002 Gr Caravan.  Do you know what's wrong? It just happened twice in the last 1/2 hr.  The first time the doors were locked and the last time I left the doors unlocked...makes no difference.  Can we disable the panic system?  We no longer have the electric key fob with the panic button and only use the key to lock and unlock from outside the vehicle. It has power locks and some times I will lock it when I get out by using the power lock switch on the drivers door.  We bought the vehicle 2 yrs ago, used.  I don't think it has an alarm system but the panic button did work before it was lost.  I'm not sure if any of this information is related but I thought too much is better than not enough.

Answer
You will recall that we exchanged q and a's earlier this month about your car. I am competing to be recognized as 'expert of the month' for November, and the voting ends Sunday afternoon. If you would consider giving me a vote, that would be most appreciated. Use the "Thank/rate" tab below where you will see "nomination?" and then change the 'no' to a 'yes' to give me that support. I hope things are well with you and your vehicle.

Hi Chris,
Unfortunately there is no straightforward way to remove a theft-alarm system which based upon the horn and flashing I believe that you do have. The best way to defeat it is to never activate it. That means you do not use the power door lock function, the door key, or the key fob to secure the doors. If you will only use the manual push-button door locks that will avoid arming the system.
It can be troubleshot, but if you don't want to go to that cost, this is the best way to go.
