if the Fire Department has ever been to your house or a neighbors house?
Experience has proven to me that many times inoperative locks are caused by bad electrical connections. The great part about it is that they're easy to repair and inexpensive if you can do it yourself. This is especially true when all of them quit because the likelihood of all the actuators going at the same time is really remote. Start at the driver's door and check all the connections by removing the terminals, cleaning the contacts then reattaching each of them. Check the locks operation after each switch is done. Since none are working I'd bet the problem is on the driver's side door switch.
Always wear a labcoat, gloves, safety goggles, report spilling/breaking of objects immediately, clear the area of any bags or other items, have a neat workstation, be organised, know what chemicals you're dealing with, familiarilise yourself with the equipment Its important to be safe.
