LiftMaster 811LMX Commercial Remote Compatibility and Programming Details
The LiftMaster 811LMX is a single-button programmable DIP remote built for commercial gate, commercial door, and compatible receiver applications. It is commonly used on shared entrances, commercial properties, gated communities, and access points where one controlled receiver channel needs a simple single-button transmitter.
This remote should be selected by receiver model and commercial radio technology. It is not a residential garage door opener remote, even though the LiftMaster name may make it look similar to residential visor transmitters.
What This Remote Does
- Provides single-button remote control for compatible commercial receiver systems
- Works with select LiftMaster commercial door operators, gate operators, and commercial receivers
- Commonly associated with compatible 850LM, 860LM, and 312HM receiver applications
- Supports Security+ 2.0 commercial default use with programmable support for select older technologies
- Can be used for one controlled entrance or one receiver channel when the site is compatible
Compatible With
- LiftMaster 850LM commercial receiver applications where supported
- LiftMaster 860LM commercial receiver applications where supported
- LiftMaster 312HM receiver applications where programming is supported
- Compatible LiftMaster commercial door operators
- Compatible LiftMaster gate operators
- Commercial access systems using supported programmable DIP remote technology
- Applications where 892LT or 894LT learning remote cloning is supported by the system
Important Compatibility Warning
The 811LMX should not be sold as a residential garage door opener remote. It is for compatible commercial receivers and commercial operator applications. Confirm receiver model, site technology, button count, programming method, and whether the system uses Security+ 2.0 commercial or supported older programmable technology before ordering.

Related Parts and Service Checks

Technician Note
Commercial LiftMaster radio systems can look similar but differ by receiver model, security technology, DIP switch handling, and programming method. Match the remote to the receiver and site technology, not just to the LiftMaster brand name.
Before Ordering Checklist
- Confirm the part number is 811LMX
- Confirm this is a commercial receiver or commercial operator application
- Confirm the receiver model is 850LM, 860LM, 312HM, or another supported commercial receiver
- Confirm the site needs one-button operation
- Confirm whether the system uses Security+ 2.0 commercial default or older programmable technology
- Do not order for LiftMaster residential garage door openers
Installation and Service Notes
Follow the receiver instructions for programming. Test the remote from a safe location with a clear view of the moving gate or commercial door. Do not use remote programming to bypass photo eyes, sensing edges, monitored safety devices, stop circuits, or access-control safety wiring.
Professional Advisory
For gated communities, warehouses, commercial doors, and managed access-control systems, confirm how remotes are tracked, issued, and removed from service. Where security and user management matter, the receiver and credential strategy should be reviewed before adding more transmitters.
