Automatically Lock
Powered by myQ technology, homeowners can open and close their garage door from anywhere* and receive alerts if its left open.
The sound of the lock engaging provides homeowners with the assurance the garage door has been secured.
When two locks are installed, the two-point locking system has been engineered, tested and approved to meet hurricane-ready requirements** by reinforcing the garage door automatically.
