The SOMMER 4078V003 is a wireless exterior entry keypad designed for SOMMER garage door openers that operate on the 310 MHz frequency. It provides secure, PIN-based access to your garage without a handheld remote or keys, making it a practical replacement part or upgrade for residential applications. Mount it outside the garage and enter your personal code to open or close a compatible SOMMER operator, enabling convenient access for family members, guests, or service providers.
This keypad communicates at 310 MHz and is intended specifically for SOMMER systems using that frequency; it is not compatible with operators or receivers on other bands such as 315, 318, 390, 433, or 868 MHz. The unit is battery-powered for truly wireless installation and is designed for outdoor mounting. Pairing typically involves using the opener’s Learn button and setting a personal PIN per the SOMMER programming instructions. For best performance, install within recommended range of the operator and keep the PIN confidential. Model number 4078V003 is an OEM SOMMER component and is suitable as a direct replacement for compatible SOMMER 310 MHz garage door openers and receivers in the North American market.
