The Digi-Code DC5040 Multi-Code Compatible Keychain Remote is a compact, single-button transmitter designed as a replacement or add-on remote for garage door openers and gate operators that use Multi-Code fixed-code technology. Built for everyday residential or commercial access control, it works with Multi-Code systems operating at 300 MHz that use a 10-position DIP switch code. Its keychain form factor makes it easy to carry, while the straightforward fixed-code design provides dependable, repeatable operation for doors, gates, and entry systems equipped with a compatible Multi-Code receiver.
Operating on the 300 MHz band with a single channel, the DC5040 uses internal DIP switches to match the code set in your existing receiver. Programming is simple: open the remote to access the DIP switches and set them to the exact on/off pattern used by the opener or external receiver, then test for proper function. This fixed-code remote is intended specifically for Multi-Code–style systems and is not compatible with rolling code platforms such as LiftMaster/Chamberlain Security+ or Genie Intellicode. For best results, verify your system’s frequency and coding style before purchase, and always ensure your door or gate safety features (photo-eyes, entrapment protections) are installed and functioning when putting a new transmitter into service.
