 That's correct. Okay. I think Carol hit the nail on the head that he was saying actuator, and yes, it does sound like you've got a door lock actuator. And a door lock actuator is basically just an electric magnet that reverses polarity in order to make it go up or go down. And over a period of time, like any other electronic part, it can go bad and the magnet get weak, and it's probably getting power to it but not able to lock and unlock.
