The Genie GICTD-3 (also labeled GICDT-3) Intellicode Key Chain Three Button Remote, part number 36484T, is a compact 3-button transmitter designed to operate compatible Genie Intellicode garage door openers and receivers. Built around Genie’s Intellicode rolling-code security, it changes the access code with every press to help prevent unauthorized entry. Its dual-frequency 315/390 MHz operation is engineered to improve reliability by overcoming common radio interference, and the three separate buttons allow control of up to three Intellicode-enabled doors, gates, or accessories—ideal as a replacement remote, spare, or upgrade for multi-door households.
Programming is performed directly at the opener or external receiver using the Learn/Program button, then pressing the chosen button on the remote until the opener confirms pairing; repeat for additional buttons and doors. This key chain remote is intended for compatible Genie Intellicode systems that operate on 315 MHz and/or 390 MHz, commonly found in residential garage door applications. For safe operation, activate the door only when it is in view and keep remotes out of reach of children. Model identifiers may appear as GICTD-3/GICDT-3 on the label, with 36484T referenced as the manufacturer part number.
