The Dolphin 433 MHz Rolling Code Keyless Entry is a wireless access keypad designed for use with compatible Dolphin gate and garage door systems operating at 433.92 MHz. It enables secure, PIN-based entry without a handheld remote, using rolling code technology that generates a unique code with every activation to help prevent code grabbing and cloning. Ideal as a replacement or upgrade for residential driveways, small commercial gates, barrier arms, and garage doors already equipped with a Dolphin 433.92 MHz rolling code receiver, it offers a convenient way to grant access to family members, visitors, or service providers.
This keyless entry accessory pairs to the opener or control board’s radio receiver through a learn/program sequence specified in the manufacturer’s documentation. Because it uses rolling code security, it is not interchangeable with fixed-code transmitters or systems operating on other frequencies (such as 315 or 390 MHz), and cross-compatibility with non-Dolphin brands should not be assumed. Installation typically involves mounting the keypad in a reachable location with clear signal path to the receiver and programming user PINs according to the opener’s manual. For best results, verify regional frequency compliance and follow all safety instructions to keep the keypad out of moving door or gate travel paths and to maintain controlled access.
