LiftMaster 813LM / 813LMX 2-Pack 3-Button Open/Close/Stop Programmable DIP Remotes
Product Overview
The LiftMaster 813LMX 2-Pack includes 2 programmable DIP remote controls for commercial door, commercial gate, and access-control receiver applications. It is intended for sites where multiple transmitters need to share the same access point or be enrolled into a compatible commercial LiftMaster receiver system.
The 813LMX uses Security+ 2.0 Encrypted DIP technology as its default format and can be configured for select older LiftMaster DIP-code formats. The 3-button layout is designed for open/close/stop commercial control, which makes it important to match the remote to the receiver channel setup and operator control logic.
This remote family is often used where property managers, gated communities, and commercial facilities need controlled transmitter distribution. It is different from a typical residential visor remote because the DIP settings, receiver capacity, and commercial receiver channel assignments are part of the compatibility decision.
Compatible With / Common Applications
The 813LMX is commonly used with compatible LiftMaster commercial door operators, commercial gate operators, built-in Security+ 2.0 commercial receivers, and external commercial receivers. Common receiver/application references include 850LM, 860LM, STAR1000, and compatible Security+ 2.0 commercial operator radio systems.
Supported code/frequency paths include Security+ 2.0 Encrypted DIP by default, plus select 315 MHz DIP and 390 MHz DIP LiftMaster applications when the receiver supports those formats. Older LiftMaster receiver families such as 312HM and 412HM are commonly associated with DIP-code commercial access paths, but the actual receiver model and frequency must be checked.
The 813LMX is the current three-button open/close/stop programmable DIP path commonly tied to 813LM, 333LM, and 33LM replacement searches where the same OCS function is needed.
Use it only when the commercial receiver or operator is configured for separate open, close, and stop commands. Button count alone does not confirm OCS compatibility.
This remote is not intended for standard LiftMaster residential garage door openers. For a residential yellow learn button opener, use the proper Security+ 2.0 residential remote such as 891LM, 893LM, 890MAX, 893MAX, or another supported model based on the learn button color.

Technician Note
For 813LMX remote packs, confirm the receiver model and programming format before issuing multiple remotes. Commercial receivers may have channel limits, master-remote procedures, or site-specific DIP settings that must be maintained consistently.
Before Ordering Checklist
- Identify the receiver model, operator model, and code/frequency format before ordering.
- Confirm whether the site uses Security+ 2.0 Encrypted DIP, 315 MHz DIP, or 390 MHz DIP.
- For open/close/stop applications, confirm the receiver has separate channels or the operator is designed for OCS remote control.
- Do not order this commercial remote for a standard residential garage door opener unless the receiver has been specifically converted to a compatible commercial receiver setup.
- Document the DIP settings or master transmitter information before replacing multiple remotes at a shared access site.
Professional Advisory
Commercial remotes should be programmed by someone familiar with the receiver and site controls. Test each transmitter only while the door or gate is visible and the travel path is clear. Never use a remote to bypass required monitored safety protection.
Product Questions & Answers
What is included in this 2-pack of 813LM remotes?
This listing is for 2 three-button LiftMaster 813LM / 813LMX style programmable DIP remotes for compatible commercial open/close/stop applications.
Is the 813LM the same as the 813LMX?
813LM is the older common part reference, while 813LMX is the current programmable DIP replacement family. Match the receiver and open/close/stop setup before ordering.
What does open/close/stop mean on this remote?
Open/close/stop means separate buttons can be used for commercial operator commands when the compatible receiver or operator is configured for those functions.
It is commonly listed as a replacement path for 333LM and 33LM style open/close/stop remotes when the receiver and programming format are compatible.
Can this remote be used with an 850LM receiver?
Yes, it is commonly used with 850LM and 860LM commercial receiver setups, especially where separate open, close, and stop channels are being used.
