Gate owners and property managers, this 811LMX gate remote is the perfect replacement for your Liftmaster system! Compatible with 850LM and 860LM receivers and commercial openers with Security+ 2.0 encrypted DIP technology, this remote works with all Liftmaster gate openers from 2016 to present. Important note: this is specifically for GATE openers, not garage door openers, so make sure you're buying the right product for your system. The dual 12-position DIP programming offers up to 4,096 possible codes, and the narrow band transmission uses encrypted digital signals that are significantly more secure than standard digital signals. You can program up to 20 or 50 remotes for your receiver, making it ideal for gated communities, commercial properties, or any situation requiring multiple access remotes. The programming process is straightforward with the included detailed manual - no special tools needed, just follow the step-by-step instructions. This remote replaces both the 811LM and 811LMX models and is compatible for cloning with 892LT and 894LT learning remote controls. Works with Security+2.0, Security+ 390 MHz, and Security+ 315 MHz for commercial products. Seriously, if you need replacement remotes for your gate system, want to add additional remotes for family or staff, or need to upgrade to more secure technology, this 811LMX delivers OEM-compatible performance without the dealership price tag. The security features provide peace of mind while the ease of programming means you can handle setup yourself without professional assistance.
