Liftmaster G891LMMC 1-button Remote Control

Product Description

The LIFTMASTER G891LMMC is a single-button remote control designed for use with Security 2.0 compatible garage door openers and gate operators. It provides encrypted wireless communication through the Security 2.0 protocol, which delivers rolling-code technology to help prevent unauthorized access. Licensed gate and door installers as well as facility maintenance technicians are the primary users for this type of device. The compact, single-button design keeps operation straightforward and is sold as an individual unit.

The G891LMMC is suited for residential and light commercial applications where a Security 2.0 compatible operator is already installed. It is a common accessory addition when additional users need their own remote, when an existing remote is lost or damaged, or when a facility manager needs to provision access for service personnel. The remote ships as a single unit (sold each).

Key Features

• Security 2.0 rolling-code encryption for enhanced access security
• Single-button operation for straightforward gate or door actuation
• Compact form factor for easy carry on a keychain or in a vehicle

Compatibility

Installation Notes

Programming is performed by a licensed door or gate installer or a knowledgeable technician following the operator unit's learn-button pairing procedure. Ensure the operator is powered and in learn mode before initiating the pairing sequence. No tools are required for remote programming, but access to the operator's learn button is necessary. Always verify the existing system supports the Security 2.0 protocol prior to purchase and installation.
