The Firefly 310MCD21K Stanley 10 Switch 310 MHz Compatible Remote is a fixed-code transmitter designed as a reliable replacement for older Stanley gate and garage door opener systems that operate at 310 MHz and use a 10-position DIP switch code. Ideal for restoring access when an original remote is lost or worn out, this handheld Firefly remote works with Stanley receivers and openers that specify 310 MHz and have a 10-switch code bank, supporting common residential and light commercial applications.
Setup is straightforward: open the remote and match its 10 internal DIP switches to the same on/off pattern found on your Stanley opener or external receiver. Once the code and frequency align, the remote will activate the connected door or gate—no “learn” button procedure is required for these fixed-code systems. This model is intended only for 310 MHz Stanley 10-switch equipment and will not work with rolling-code technologies or other frequencies such as 300, 315, 318, or 390 MHz. For best results, verify your opener’s frequency label and DIP count before ordering. Use responsibly and test operation from a safe location to ensure proper function in your specific installation.
