811LMX Gate Opener Remote Replacement for Liftmaster - 4 Pack

Our review of the 811LMX Gate Opener Remote Replacement finds it most useful for property managers, commercial facilities, and homeowners who need a compact, programmable remote for LiftMaster gate systems. The single biggest reason to buy is compatibility with Security+ 2.0 commercial receivers such as LiftMaster 850LM, 860LM and STAR1000, which lets multiple remotes be cloned or programmed to the same channel without replacing existing receivers. This review focuses on real-world fit, programming and daily use rather than marketing claims.

Key Features

• Compatibility: Works with LiftMaster 850LM, 860LM and STAR1000 receivers, making it a straightforward replacement for many commercial gate setups.
• Programmable 12 DIP switches: The 12-DIP configuration offers up to 4,096 code combinations for improved access control compared with simple fixed-code units.
• Security+ 2.0 encryption: Narrowband encrypted transmission reduces interference and improves security when paired with compatible receivers.
• Multiple frequencies: Supports Security+ 2.0, 315 MHz and 390 MHz frequencies to match different receiver requirements and cloning scenarios.
• Cloning options: Can be cloned with learning remotes such as models 892LT and 894LT so adding extra transmitters is simple when a receiver channel is already in use.
• Pack of four: Four remotes in a single pack make it convenient for multi-user installations or as spares for staff and tenants.

Who It's For

The 811LMX is best for facility managers, gate service technicians, and homeowners responsible for commercial-style gate operators using LiftMaster Security+ 2.0 receivers from 2016 onward. It is particularly handy when multiple users need separate remotes or when adding replacements without changing receiver hardware.

Those who should look elsewhere include owners of older rolling code garage door openers or Performance series models, because the 811LMX is not compatible with garage openers and is intended for commercial gate and door operators. If long remote range is critical, check receiver placement and user reports, as range performance varies by installation.

Pros & Cons

Pros

• Direct compatibility with common LiftMaster commercial receivers simplifies replacement without receiver changes.
• Programmable 12-DIP design provides a large code space and flexibility for shared installations.
• Security+ 2.0 support and narrowband encryption reduce interference and improve signal security.
• Sold in a four-pack for convenient distribution to multiple users or as spares.

Cons

• Reported range is mixed among users, so installations with distant receivers may see reduced performance.
• Not compatible with garage door openers or some non-Security+ 2.0 receivers, limiting universal use.

Our Verdict

The 811LMX replacement remote is a practical, cost-effective choice for anyone maintaining LiftMaster Security+ 2.0 gate receivers: it offers cloning flexibility, a large code space and encrypted transmissions in a four-pack that covers multiple users.

Frequently Asked Questions

Will this remote work with my LiftMaster receiver?
It is compatible with LiftMaster 850LM, 860LM and STAR1000 receivers and other commercial openers using Security+ 2.0; it is not designed for standard garage door openers.

Can I program multiple remotes to the same receiver channel?
Yes, you can program or clone several 811LMX remotes to the same receiver channel by replicating the DIP switch settings or using a compatible learning remote.

What kind of range can I expect?
Typical range is around 150 ft in open conditions, but real-world range varies with receiver location, antenna placement and site interference.
