I have to assume that you are talking about electronic lock actuators? We have seen the lock actuators fail in all doors. This is due to one actuator that fails and draws down the current in the system. The remaining lock actuators then fail due to the lower current. They make a growling noise when they fail during actuation.
One door making more noise than others or all seem to be noisey?
