FAQ Section
Q: How do I program the 893LM remote to my garage door operator?
A: Press and immediately release the Yellow Learn Button on the back panel of the operator motor head (the learn LED will glow steadily). Within 30 seconds, press and hold the desired button on the 893LM remote until the operator lights blink or two audible clicks are heard.
Q: Will this remote work with older LiftMaster models that have a purple, red/orange, or green learn button?
A: No. The 893LM is strictly engineered for Security+ 2.0 systems featuring a Yellow Learn Button. It will not communicate with older Security+ (purple/red) or Billion Code (green) receivers due to incompatible frequency and encryption formats.
Q: Can I program one button for my home garage and another for my community gate?
A: Yes, provided both systems utilize compatible Security+ 2.0 technology with a Yellow Learn Button. Each of the three buttons acts independently.
Q: How do I clear the remote's access if one of my clickers is lost or stolen?
A: You must clear the receiver's memory to disable the lost remote. Press and hold the Yellow Learn Button on the operator for approximately 6 seconds until the learn LED turns off. This erases all programmed remotes and keypads, requiring you to reprogram any remaining authorized devices.
Q: How do I change the internal battery when it runs low?
A: Insert a small flathead screwdriver or the edge of the visor clip into the side seam of the remote casing and gently pry it open. Slide the old CR2032 battery out of the holding bracket and insert the new one with the positive (+) side facing up, then snap the casing firmly back together.
