The Dolphin 315/390 MHz 9 Switch Keyless Entry is a wireless exterior garage door keypad designed for select Chamberlain, Craftsman, and LiftMaster openers that use a fixed-code, 9-switch (DIP switch) system. It lets you open and close a compatible garage door by entering a personal PIN, providing convenient keyless access without carrying a remote. Identified by its 315/390 MHz compatibility and 9-switch coding, this replacement keyless entry is intended for older, fixed-code garage door operators commonly found in many legacy residential installations.
Installation and setup follow the fixed-code method: match the keypad’s internal 9 DIP switches to the switch pattern on your opener’s receiver or an existing compatible remote, then set your personal PIN according to the included instructions. Because it relies on 9-switch coding, this keypad is not compatible with rolling-code systems that program via a learn button (e.g., Security+ and Security+ 2.0 models) or openers without DIP switches; verify your opener uses a 9-switch code and operates at 315 MHz or 390 MHz before purchasing. Use this Dolphin keyless entry as a straightforward replacement or upgrade for older Chamberlain, Craftsman, and LiftMaster fixed-code systems where simple, PIN-based access is desired.
