The Stinger 300MCD21V is a two-button visor remote engineered to work with Linear Multi-Code fixed-code systems operating at 300 MHz. Designed as a dependable replacement or add-on transmitter, it activates compatible gate operators and garage door openers with simple, reliable performance, making it useful for both residential and light commercial applications. Each button can control a separate door or gate, providing convenient multi-door control from one compact transmitter.
This Multi-Code compatible remote uses fixed-code DIP-switch programming, allowing you to match the switch pattern of your existing Multi-Code 300 MHz receiver or transmitter for quick setup—no rolling code pairing required. It is intended solely for 300 MHz Multi-Code systems and will not work with Security+, Security+ 2.0, Genie Intellicode, or other rolling-code platforms. Typical installation involves opening the remote, setting the internal code switches to the same pattern as the receiver, and clipping the transmitter to a vehicle visor. Ideal for buyers searching for a Linear Multi-Code compatible replacement remote, 300 MHz gate/garage opener remote, or a two-button visor transmitter, the 300MCD21V offers straightforward programming and dependable operation when used with proper 300 MHz Multi-Code equipment.
