The LiftMaster 813LM is a Security+ 2.0 Encrypted DIP remote control designed for reliable, multi-door control of compatible LiftMaster commercial gate operators and commercial/industrial garage door openers. Featuring three programmable buttons, it can operate up to three doors, gates, or receiver channels from a single transmitter, making it a practical replacement remote or upgrade for multi-tenant facilities, parking areas, and commercial sites. Security+ 2.0 encryption transmits a unique, secure code with every press, and tri-band radio technology helps maintain consistent performance in high-interference environments.
This Encrypted DIP transmitter operates on Security+ 2.0 tri-band frequencies (310/315/390 MHz) and uses internal DIP switches for programming; set the remote’s DIP switches to match the site/receiver code rather than using a learn-button sequence. It is compatible with LiftMaster receivers and control boards that specifically support Security+ 2.0 Encrypted DIP, such as the LiftMaster 850LM Universal Receiver, and with operators equipped for Encrypted DIP inputs; it does not program directly to legacy fixed-code or older Security+/learn-button-only systems. Typical setup requires access to the receiver to align the DIP settings, and power is supplied by a 3V coin-cell battery. For best results, consult the receiver/operator manual to confirm Encrypted DIP compatibility and channel assignment before programming.
