The Keystone Heddolf Genie GRC315/390-3KB is a 3-button, Intellicode-compatible garage door remote designed as a dependable replacement or add-on transmitter for Genie openers. Built to work with many generations of Genie Intellicode rolling-code systems, it provides secure, convenient control of one to three garage doors or gate operators. Its dual-frequency design supports both 315 MHz and 390 MHz Intellicode receivers, helping ensure compatibility across newer and older Genie installations in residential settings.
Programming is straightforward: place the Genie opener or compatible external receiver into Learn/Program mode and press the chosen button on the remote to sync—no dip switches required. This transmitter is intended for Genie garage door operators that use Intellicode rolling code technology operating on 315 or 390 MHz; it is not designed for pre-Intellicode, fixed-code models or systems using other radio protocols. For safe operation, pair only with a properly maintained opener with functional safety reversing sensors, and test the door after programming. Ideal for buyers seeking a replacement remote, an upgrade for dual-frequency compatibility, or an additional controller for everyday residential use.
