• Answer:

  Maybe asking your question in the Chevrolet section would bring in more responses, this one is for Fords but... On most cars your problem sounds a lot like the actuators are bad. However if all the locks stopped responding to the button and remote at the same time its more likely that you have a bad switch or electrical connection as its not likely they would all go bad at one time, unless... If you have kids and one of them took the time to hold down the lock button for an extended period of time it could have tripped an overload component of the actuators causing them all to quit at the same time. If that's the case on most cars they're not repairable and will have to be replaced, on others it is possible to replace the overload component.
