LiftMaster 811LMX Single-Button Programmable DIP Remote
The LiftMaster 811LMX is a single-button programmable DIP-switch remote for commercial access applications. It is commonly used with compatible LiftMaster commercial door operators, gate operators, and commercial receivers where a commercial remote format is required.
The default operating format is Security+ 2.0 Encrypted DIP. The remote can also be configured for select older LiftMaster 315 MHz DIP and 390 MHz DIP devices when the receiver/security type is compatible.
Compatibility and Application
Use the 811LMX for compatible LiftMaster commercial products, gate operators, commercial door operators, and commercial receivers. It is not intended for standard LiftMaster residential garage door openers.
For older DIP systems, confirm whether the receiver uses Security+ 2.0 Encrypted DIP, 315 MHz DIP, or 390 MHz DIP. Matching only the number of DIP switches is not enough to confirm compatibility.

Technician Note
The 811LMX is frequently confused with residential remotes. If the customer has a home garage door opener with a standard learn button, this is usually not the correct remote unless an external compatible commercial receiver is installed.
Before Ordering
- Confirm the receiver is a LiftMaster-compatible commercial receiver or operator.
- Identify whether the system uses Security+ 2.0 Encrypted DIP, 315 MHz DIP, or 390 MHz DIP.
- Do not use this remote for a normal residential garage door opener learn-button application.
- Match the existing DIP/security-type setup or program the receiver as required.
- For controlled facilities, confirm authorization before adding or duplicating transmitters.
Professional Advisory
Commercial gate and door systems can create serious hazards if programmed or tested carelessly. Keep the door or gate in sight during testing, and have unsafe movement, failed safety devices, or high-voltage control issues handled by a qualified technician.
