LiftMaster 1-5 Error Code: Remote Control or Learn Button Issue

Quick Answer

1-5 fires when the opener receives a continuous button signal it cannot process normally. Remove batteries from each remote one at a time to find the stuck button.

LiftMaster 1-5 means the opener detects a continuously held button signal from a remote, keypad, or the Learn button. The opener locks out all commands while the button is stuck to prevent accidental operation. Check all remotes for a stuck button, remove batteries from each remote one at a time to isolate the problem device, and check the wall keypad for a stuck key.

Frequently Asked Questions

Why would my LiftMaster suddenly stop responding to all remotes at once?

When one remote has a stuck button, the opener enters a lockout state and ignores all incoming transmissions. This is a safety feature. Find the stuck remote by removing batteries one at a time until the motor unit LED blink pattern changes.

Can a remote cause 1-5 errors even from inside the house?

Yes. LiftMaster remotes typically have a range of 50 to 100 feet. A remote stuck under a couch cushion or in a drawer inside the house can transmit continuously and lock out the opener.

I removed batteries from all remotes and the 1-5 code still shows. What next?

Check the exterior keypad for a stuck key, and verify the Learn button on the motor unit is not physically depressed. If none of these are the cause, a logic board fault may be generating a false 1-5 reading.

How do I prevent the keypad from getting sticky keys?

Install a weatherproof cover flap over the keypad, or periodically spray the keypad face with a silicone protectant to repel moisture. Avoid using the keypad with wet or muddy hands, which introduces moisture under the keys.

After fixing the 1-5 code, do I need to reprogram my remotes?

No. Removing and reinstalling batteries does not erase the remote's programming. Once the battery is reinstalled in the corrected remote, it will work with your opener exactly as before.
