### What Is It Used For?
The 891LM allows you to remotely operate one compatible LiftMaster device from your vehicle.

Pressing the button sends an encrypted Security+ 2.0 signal to the programmed device.
### Security+ 2.0 Technology
The 891LM uses LiftMaster Security+ 2.0 wireless technology.
Security+ 2.0 uses encrypted communication between the remote and compatible opener to help protect against unauthorized code duplication.
The easiest way to identify a compatible residential opener is by checking for a:
YELLOW LEARN BUTTON
on the garage door opener powerhead.
### Important Compatibility Notice
The 891LM is NOT a universal LiftMaster remote.
It is designed specifically for compatible Security+ 2.0 systems using a Yellow Learn button.
It should not be assumed compatible with older LiftMaster openers using:
- Green Learn Button
- Red / Orange Learn Button
- Purple Learn Button
- DIP-switch systems
For older systems requiring broader compatibility, a LiftMaster MAX-series or current multi-generation remote may be more appropriate.
Always verify the Learn button color before ordering.
### 891LM vs. 893LM
891LM:
- 1 button
- Controls 1 compatible device
893LM:
- 3 buttons
- Controls up to 3 compatible devices
Both are designed for Security+ 2.0 / Yellow Learn Button systems.

1 × 3V CR2032 lithium coin-cell battery
The battery is replaceable.
LiftMaster states that the battery can provide approximately three years of service under typical use conditions.
A weak battery may result in:
