About the LiftMaster 841LM Automatic Garage Door Lock
LiftMaster 841LM Automatic Garage Door Lock

Features
Automatic Operation: Performs in tandem with the opener, so it always locks and unlocks.
Anywhere Assurance: Powered by myQ technology, homeowners will have the ability to open and close their garage door from anywhere and will receive alerts if it's left open.
Safety and Security
Absolute Protection: A deadbolt lock reinforces the garage door automatically when the garage door is closed.
Audible Security: The sound of the lock engaging provides homeowners with the assurance the garage door has been secured.
