OEM Upgrade 811LMX Gate Remote for LiftMaster – Security+ 2.0, 390/315 MHz, 2-Pack

Overview

Upgrade your LiftMaster gate access with the OEM Upgrade 811LMX remote. This two‑remote pack is designed to work with LiftMaster 850LM and 860LM receivers and supports Security+ 2.0 encrypted DIP technology, compatible with 390 MHz and 315 MHz bands. Built for gates that started life in 2016, this remote adds a flexible, secure control option for homes and small to mid‑size facilities.

• Compatibility with 850LM and 860LM receivers, plus commercial openers using Security+ 2.0 encrypted DIP technology.
• Replacement and cloning options, including compatibility with 892LT and 894LT learning remotes.
• Dual 12‑position DIP programming with up to 4,096 codes and encrypted signals for reliable operation.

The 811LMX is a scalable solution for larger needs. You can set up 20 or 50 remotes per receiver, making it suitable for communities or small businesses. If you need more, you can copy the code from an existing remote to expand access without reprogramming everything.

• Large remote capacity per receiver to fit medium to large sites.
• Code mirroring across remotes to simplify expansion.

Programming is straightforward with the included manual. Before you begin, open the remote slider and move the code to the desired location, then follow the step by step instructions. No special tools are required, enabling installation in busy entry points.

This 2‑pack aligns with LiftMaster ecosystems and Security+ 2.0 operations, offering a straightforward upgrade path for families, property managers, and business owners seeking controlled access for multiple users.

Real world usage

In residential gates, expect a clean signal strength across typical driveways. In commercial settings, the larger code capacity and several remotes help maintain orderly entry for approved users.

Tips for best results

• Avoid sources of interference during programming and keep remotes labeled by area or user.
• Follow the slider positioning in the manual to ensure the correct code is selected.

Note that actual performance can vary with hardware and environment. Consider this remote as a flexible option within the LiftMaster ecosystem rather than a guaranteed universal remedy.
