The Genie GICT390-3BL Intellicode Key Chain Three Button Remote (part number 36484U) is a compact, handheld transmitter designed to operate Genie garage door openers that use Intellicode rolling code security at 390 MHz. With three programmable buttons, it can control up to three separate Genie Intellicode receivers or doors, making it an ideal replacement remote or spare for residential applications. Intellicode technology automatically changes the access code with every press to help prevent unauthorized entry, and the key chain form factor makes it convenient to carry on a key ring or in a pocket.
This transmitter is compatible with most Genie openers equipped with Intellicode at 390 MHz (commonly used on many units produced in the late 1990s and 2000s). It is not compatible with older DIP-switch style systems or newer Intellicode II dual-frequency systems (315/390 MHz) unless an appropriate 390 MHz Intellicode external receiver is added. Programming typically requires access to the opener’s Learn Code/Program button: press the Learn button on the motor head, then press the desired button on the GICT390-3BL twice to complete pairing; repeat for additional buttons or doors. For safe operation, use only with door operators that have working safety reversing sensors and follow the manufacturer’s installation and programming instructions.
