Review on 🔒 LiftMaster 811LM Encrypted DIP Remote Control with Security+ 2.0 Technology for Enhanced SEO by Aravind Joshi

811LM has ended. While the 811LMX is said to be compatible with the 811LM, the 811LMX is said to have a feature that could prevent it from being used in a closed community. I returned without a test as the gate I am buying them for is 1000 miles away from me. When I received the 811LMX I did a compatibility search and found the following note on the reseller site (which was cheaper btw): NOTE. There is a problem using this remote control as a replacement for 61LM, 361LM or 811LM. Remote controls, it will NOT clone any remote that has DIP switch #1 in the "on" position or any switches in the middle or "0" position. Program the new 811LMX directly into the system. This allows both old and new 811LMX consoles to control the system. Problem. I can't verify this "NOTE" but I have to assume you know what you are talking about. In any case, buy with caution.
