811LM Gate Remote Control Replacement for Liftmaster - Secure 4-Pack

In this review of the 811LM gate remote replacement, the bottom line is simple: it is a practical, secure option for commercial gate systems that use 850LM or 860LM receivers. The reviewer found the remotes most valuable for facilities that need multiple transmitters programmed to the same receiver, because the 12 dip switches and encrypted Security+ 2.0 signaling make the unit reliable for controlled access. It is not a universal garage remote, so residential users with incompatible models should confirm compatibility before buying.

Key Features

• Compatibility: Designed specifically for commercial systems using 850LM and 860LM receivers, ensuring a match when those receivers are in place.
• Security+ 2.0: Uses encrypted DIP programming with 12 code switches so up to 4096 code combinations reduce the chance of interception.
• Programmable: Includes a detailed user manual that walks through setting the dip switches and syncing multiple remotes to a single receiver.
• Pack size flexibility: Sold as a 4 pack which makes it convenient to deploy multiple remotes for staff, contractors, or spare units.
• Build quality: Customers reported a solid, non-flimsy feel and responsive buttons, indicating the units hold up to regular use.

Who It's For

The 811LM replacement remote is best for businesses, property managers, and commercial gate installers who operate gates tied to Liftmaster 850LM or 860LM receivers and need multiple secure transmitters. It fits scenarios where encrypted signals and a straightforward dip-switch programming method are priorities.

It is not for typical residential garage door owners or anyone using incompatible models such as 8550 or 8360, because those systems use different protocols. Buyers who need a completely universal remote or a different receiver family should look elsewhere.

Cons

• Not universal - incompatible with many residential openers, so buyers must verify their receiver model first.
• Some users reported mixed functionality and range on certain gate installations, so performance can vary with site conditions.
