Product features and benefits Broad compatibility: Designed to work with swing and sliding gate openers, including Lockmaster, Topens, and Casar systems. Also compatible with third‑party gate control boards that accept a 'Normally Open (NO) Dry Contact' push‑button input. Reliable radio performance: Operates at 433.92 MHz and reliably controls non‑encrypted gates from distances up to 65 feet, giving consistent operation for typical driveway and entryway setups. Compact and portable: Small, lightweight remote that easily fits on a keyring or in a pocket so you can carry it wherever you need it. Simple setup: Fast pairing using the programming button on the gate opener control board. Add the remote to your system quickly and start opening and closing the gate with a single press. Flexible control options: A single remote can operate multiple gate openers at once if they are within range and share the same signal. One M12 remote can control multiple operators separately—for example, up to four swing gate openers, or one sliding gate motor plus two swing gate openers. Clear operation pattern: Each press cycles the gate through open → stop → close → stop → open, matching standard push‑button control behavior. Enhanced signal protection: Includes security code technology to reduce radio interference and help protect the operating signal. The remote generates a security code each time it is used on your opener, improving resistance to interference and unauthorized access. How it solves common problems Replaces lost or broken remotes: Restores remote control without rewiring the gate system when you need a direct, compatible replacement for Lockmaster, Topens, Casar, or other NO dry contact control boards. Simplifies multi‑gate control: Use one handheld remote to manage several gates on the same property or nearby entrances instead of carrying multiple transmitters. Avoids complicated programming: Pairing with the control board programming button avoids complex setup procedures and gets the system back in service fast. Typical use scenarios Residential driveway: Mount the control board in the garage or post and pair the remote to open a swing or sliding driveway gate up to 65 feet away. Small commercial property: Use one M12 remote to manage an entry sliding gate motor and two side swing gates, providing centralized access control for staff or service vehicles. Replacement for specific brands: Quickly missing remotes for Lockmaster, Topens, or Casar installations that use a 433.92 MHz, non‑encrypted remote and a NO dry contact control input.
