The Marantec Digital 382 is a 2-button keychain garage door opener remote designed for Marantec systems that use 315 MHz radio technology. It functions as a convenient replacement or spare transmitter, allowing you to control up to two Marantec operators or accessories from a compact fob. Typical applications include residential garage doors and compatible Marantec light/control modules. This model is engineered for Marantec-branded openers running 315 MHz, including many M-Line and Synergy series operators, and it can also operate with Marantec 315 MHz external receivers when present. It is not a universal remote and will not work with other brands unless a compatible Marantec receiver is installed.
Operating at 315 MHz with a 3V lithium coin-cell battery, the Digital 382 offers reliable, secure radio control consistent with Marantec’s coding system. Programming can be completed by transferring the code from an existing, working Marantec remote using the Marantec programming connector method, or by placing the operator into learn/program mode and pairing the new transmitter according to the opener’s manual; each button can be assigned to a different door or function. An LED confirms transmission during use. For best results, follow Marantec’s published programming and safety instructions, keep the remote and battery out of the reach of children, and use only compatible Marantec 315 MHz operators such as select M-Line models (e.g., M4500/M4700 series) and Synergy openers (e.g., Synergy 260/270/280/360/370/380).
