The Marantec 69625 Remote Programming Connector is an OEM accessory designed to simplify cloning and setup of Marantec M3 series garage door opener remotes. By linking a working transmitter to a new or replacement transmitter through their programming ports, this connector enables quick transfer of the existing code so the new remote mirrors the donor’s credentials. It is commonly used with Marantec North American M3 radio controls (315 MHz models) found on many Synergy operators and compatible residential systems, making it a practical replacement part for restoring lost remotes or expanding control to additional users.
Using the connector is straightforward: install batteries in both remotes, insert the 69625 into the programming ports of the donor and recipient remotes, then follow the transmitter-specific button sequence until the status LEDs confirm a successful copy. In many setups, the opener’s learn routine may still be required to complete registration of the new remote. This passive connector requires no external power and is intended exclusively for Marantec M3 transmitters; it is not a universal programming tool for other brands or frequencies. For safe operation, perform programming away from moving doors and test functionality only when the doorway is clear. Marantec Part No. 69625 is a simple, durable way to add, replace, or upgrade remotes within compatible Marantec M3 315 MHz systems in residential applications.
