LiftMaster 811LMX Single Button Programmable DIP Remote Control
The LiftMaster 811LMX is a one-button programmable DIP-style remote control made for commercial access applications. It is used with compatible LiftMaster commercial gate operators, commercial door operators, and commercial radio receivers where a single open/close command is needed. The remote is commonly selected for gated communities, commercial lots, service entrances, and facilities that need simple access control without extra buttons.
The 811LMX defaults to Security+ 2.0 commercial encrypted DIP operation and can be set up for certain older 315 MHz or 390 MHz DIP applications when the receiver and system support that mode. This makes it useful for some mixed commercial sites, but it also means compatibility must be checked carefully. It is not a normal residential garage door opener remote and should not be sold as a replacement for standard residential Security+ or Security+ 2.0 garage remotes.
Common receiver references include the LiftMaster 850LM and 860LM, with 312HM often appearing in related applications. The actual compatible setup depends on the receiver installed at the site, its programming mode, and the operator or access control panel connected to it.

Technician Note
Do not match this remote by button count alone. A one-button LiftMaster remote can use several different radio technologies, and the 811LMX is specifically for compatible commercial receiver systems.
Before Ordering
- Identify the receiver model at the site, not just the gate operator model.
- Confirm whether the system uses Security+ 2.0 commercial encrypted DIP, 315 MHz DIP, or 390 MHz DIP.
- Do not order this for a standard residential garage door opener.
- Check whether the existing transmitter is marked 811LM, 811LMX, or another commercial model.
- Plan to program the remote to the receiver according to the receiver instructions.
Important Ordering Warnings
- Not compatible with standard LiftMaster residential garage door openers.
- Receiver model and programming mode control compatibility more than the gate operator model alone.
Professional Advisory
Programming commercial radio controls should be done only with proper authorization from the property owner, manager, or access control administrator.
Product Questions & Answers
Is the 811LMX for residential garage door openers?
No. It is intended for compatible LiftMaster commercial door operators, gate operators, and commercial receivers, not standard residential garage openers.
What receivers are commonly used with the 811LMX?
Common references include the LiftMaster 850LM and 860LM, with select 312HM applications depending on frequency and programming mode.
Is 811LMX the same as 811LM?
811LM and 811LMX are closely related commercial single-button remote references. Check the receiver instructions and exact transmitter label before replacing an existing remote.
Can it work with older DIP switch systems?
It can be programmed for certain older 315 MHz or 390 MHz DIP-style commercial systems when the receiver supports that setup.
Why will my 811LMX not program?
The receiver may be the wrong technology, locked by site management, full of stored transmitters, or set for a mode that does not match the remote.
