The Allstar 109391 Single Button Classic Key Chain Remote (model 9931MT) is a compact, one-channel transmitter designed for everyday control of compatible garage door openers, gate operators, and access control receivers. Built for quick, one-touch operation from a key ring, it serves as a reliable replacement remote or spare for Allstar/Allister Classic systems in residential or light commercial environments where simple, secure access is needed.
This Classic-series transmitter is commonly associated with 318 MHz Allstar/Allister technology and uses DIP-switch code programming, allowing installers and users to match the internal switch pattern to a compatible receiver for fast setup—no computer tools required. It is intended for Classic fixed-code receivers and operators and is not compatible with rolling-code platforms like Linear MegaCode or other brands/frequencies. Typical use cases include replacing a lost or damaged remote, adding a new handheld control to an existing Allstar Classic DIP-switch receiver, or pairing with access systems that specify Classic Allstar/Allister compatibility. For safety and best performance, confirm the receiver’s frequency and code type on its label or manual before ordering, set unique codes to reduce interference, and test operation from a safe distance after programming.
