The Genie GICT390-1BL (also referenced as GICDT390-1), part number 36484R, is a one-button Intellicode key chain remote designed for Genie garage door openers that operate on the 390 MHz Intellicode rolling-code platform. This compact key fob transmitter provides secure access with Genie’s Intellicode technology, which changes the access code with every press to help deter code grabbing. Ideal as a replacement or an additional remote, it attaches to your key ring for quick entry to residential garage doors or compatible gate operators that use Genie Intellicode at 390 MHz.
Compatibility is limited to Genie openers and receivers using Intellicode at 390 MHz (commonly associated with earlier Intellicode systems). It is not intended for fixed-code DIP-switch systems, non-Intellicode equipment, or newer systems that require dual-frequency Intellicode II remotes unless the receiver specifically supports 390 MHz Intellicode. Programming is straightforward: access the opener’s Learn/Program button, initiate learn mode on the operator, then press the remote’s button until the operator responds; consult your opener’s manual for model-specific instructions and indicators. For safe operation, only activate the door when it is in full view and keep remotes out of reach of children.
