The LiftMaster 811LMX and 813LM 1 & 3 Button Transmitters feature Security+ 2.0 and 12 programmable DIP switches. A 5-year 3-volt battery is included as well. The LiftMaster Remote Control works on a simultaneous 310, 315, and 390 MHz frequency and can be set to work for a garage door or a gate on the property.

We here at GateCrafters offer the single button version of the LiftMaster 800 series control. With the dual and triple button transmitter, you can use the transmitters on multiple garage doors, gate openers or any combination that works for you.

	GateCrafters.com has actual experience. We have a testing area, we have factory and internal training courses, we build gates and have our own automated gates, we attended all industry trade shows in multiple countries and are a member of the AFA, and we pay visits to our chosen manufacturers' factories. All these factors are what have lead to us having so many exclusive additions. When you see and actually use as many products as we have you tend to have many ideas for minor changes that have major impacts. We acted on these ideas and have utilized them to help thousands of customers automate their gates.
