LiftMaster 371LM Remote

Your LiftMaster 371LM at a glance

Confirm that the label says LiftMaster 371LM. Preserve any additional suffix or hardware-revision marking; a matching shell or model number used by another brand is not enough.

This is a 315 MHz Security+ remote.

371LM battery & holder

CR2032, 3 V, positive side upward in the illustrated holder.

Programming your 371LM

Setup depends on the exact receiver and hardware revision. These model notes do not establish a complete pairing sequence for your equipment.

Match both the remote and opener or external receiver. Keep the door or gate in sight and clear of people. Do not hold a LEARN button or erase memory unless the instructions for that exact equipment require it.

Compatibility & exclusions

The original guide specifies purple-learn-button openers and compatible universal receivers.

Check the exact receiver when using an external receiver.

If your 371LM is not working

General troubleshooting checks.

• No response: check the marked battery type and polarity; note whether another authorized control works.
• Short range: note when the problem began and whether it changes by location. Do not alter receiver wiring.
• Damaged case or buttons: keep the model label; stop using exposed, wet or damaged electronics.

371LM repair, parts & replacement

No exact replacement or part mapping has been confirmed for this page. A similar-looking remote, matching frequency or familiar model family is not sufficient evidence of interchangeability.

Model guides

Use the model-specific notes on this page with the instructions for your opener or receiver. A documented receiver match does not establish compatibility with every opener.
