LiftMaster 891LM 1-Button Security+ 2.0 Remote Control
The LiftMaster 891LM is a single-button remote control for operating one compatible Security+ 2.0 access device. It is a clean, simple option when the customer only needs control of one garage door opener, gate operator, or compatible LiftMaster receiver channel.
This remote is part of the LiftMaster Security+ 2.0 family and is most commonly paired with openers that have a yellow learn button. It is not intended to replace older 315 MHz purple button, 390 MHz red/orange button, green Billion Code, or fixed-code DIP-switch remotes.
Compatibility and Application
Use the 891LM with compatible LiftMaster, Chamberlain, Craftsman, and related openers or receivers using Security+ 2.0 technology and a yellow learn button. It is a good match for newer residential garage door opener applications where only one button is needed.
If the existing system uses a purple, red/orange, or green learn button, use the correct remote family or a compatible MAX or learning remote instead. Matching by appearance alone can lead to the wrong transmitter.

Technician Note
The fastest way to confirm this remote is to look for the yellow learn button near the opener antenna wire or on the receiver. A wall button or outside keypad style does not confirm radio compatibility.
Before Ordering
- Confirm the opener or receiver uses a yellow learn button.
- Use this remote when only one button is needed.
- Do not order for purple, red/orange, green, or DIP-switch systems.
- Check whether the receiver memory is full if the remote will not add.
- Clear the door or gate area before testing after programming.
Professional Advisory
Programming should be performed with the moving door or gate in clear view. If the opener has missing or failed safety sensors, damaged wiring, or unsafe movement, have the system inspected before adding new transmitters.
Product Questions & Answers
What learn button color does the 891LM use?
The 891LM is used with compatible Security+ 2.0 systems that have a yellow learn button.
Can the 891LM replace a 371LM or 971LM?
No. The 371LM is a 315 MHz purple-button remote and the 971LM is a 390 MHz red/orange-button remote. The 891LM is for yellow Security+ 2.0 systems.
Is the 891LM good for one garage door?
Yes. The 891LM is a single-button remote and is commonly used when only one compatible opener or receiver channel needs to be controlled.
Can this remote operate a community gate?
It may be used with a compatible Security+ 2.0 gate receiver or operator channel, but it will not work with every community gate radio system.
What should I check if the opener does not learn the remote?
Check the learn button color, receiver memory, remote battery, antenna condition, and whether the opener is actually a Security+ 2.0 model.
