The Linear GT-31 is a compact three-button key chain remote designed to operate Genie Intellicode 1 systems, making it a practical replacement for the Genie ACP00870 remote. Engineered for rolling-code security, this transmitter can control up to three separate Intellicode 1-enabled garage door openers, gate operators, or external receivers, offering a convenient upgrade or spare for residential or light commercial access applications. Its small, portable form factor keeps reliable control at your fingertips for everyday use and service replacements.
Programming is performed at the opener or receiver using the Learn/Program button, then pressing the desired button on the GT-31 to sync—a quick process commonly used with Genie Intellicode equipment. This model is intended specifically for Intellicode 1 compatibility and is not designed for fixed-code/DIP-switch systems or Intellicode 2-only platforms. For best results, program within close range of the operator and verify your opener or receiver supports Intellicode 1 before purchase. Typical use cases include replacing a lost or worn remote, adding a spare transmitter, or consolidating control of multiple Intellicode 1 doors and gates into a single three-button remote.
