Automatic garage lock 841lm
LiftMaster provides an automated garage door lock, the 841LM, to enhance the security of your home by automatically locking your garage door when it's closed. The 841LM is a standard feature of the 8500W model and is available as an option for select other models.
The opener casing of compatible models will display the shield logo to indicate the ability to install the lock. Furthermore, the myQ app will display the shield logo on the opener with an installed lock.
It is worth noting that some models can support up to two locks, including the 87802, 8550WLB, 8550WL, 8580WLB, 8587W, 8360WLB, and 8500W (one lock included, with the option to add a second one). By adding the 841LM lock to your LiftMaster garage door opener, you can ensure an extra layer of security for your home.
