Why do my car doors lock themselves while my car is parked,its a 2001 Honda crv.?
 

I can put my car in the garage and come back to find the automatic locks have engaged, its very annoying.

It probably has an alarm that is set to lock after a few minutes. its annoying but it helps you so if you forget to lock your car it does it automatically. You can get teh manual and should be about to reprogram it to a diff setting.
