LiftMaster 841LM Automatic Garage Door Lock: Wi-Fi connectivity for smart home integration
For homeowners who have already upgraded to a smart garage door opener, the LiftMaster 841LM Automatic Garage Door Lock adds the missing piece: true deadbolt security. You can now lock your garage door from your smartphone and set it to engage automatically every time the door closes.
The heavy-duty steel lock creates a strong barrier against forced entry. Installation is straightforward with the included hardware, template, and 33' wire. Once connected, you can check lock status and control it remotely via your myQ app, knowing your door is secure even when you're away.
Compatibility: Works with LiftMaster models 8550WL, 8587WL, 8360WL, and 8500W. Check your owner's manual to confirm compatibility before purchase.
