Why Remotes Stop Working
Dead battery. The most common reason by far. Remotes that work only close up often have a weak battery.
Lock mode. Many wall controls have a lock button. Pressed by accident, it blocks every remote and keypad while the wall button still works. Often a light blinks to show it's on.
Lost programming. A power surge or a battery swap can wipe the codes. Reprogramming takes a minute with the learn button.
The LED Bulb Problem
Some cheap LED bulbs give off radio noise that drowns out the remote. The sign is a remote that only works when you're almost under the door.
Test it by removing the bulbs from the opener. If range comes back, replace them with bulbs sold for garage door openers.
Keypad Trouble
Outdoor keypads take a beating from heat, rain and salt air. If yours stops responding, change the battery first, then reprogram the code.
Corrosion on the contacts is common near the water. A keypad that's cracked or fogged inside is cheaper to replace than to fix.
Car Buttons and Phone Apps
Many cars have built in garage buttons that learn your remote's signal. If you replace the opener or reprogram remotes, those buttons usually need to learn again too. The car's manual has the steps.
Phone apps need the opener connected to your home wifi. If the app stops working after a router change or an outage, reconnecting the opener to wifi is usually the fix.
Guest codes on a keypad are worth changing now and then, especially after a contractor or a renter.
When It's More Than the Remote
If the wall button doesn't work either, the opener or its power is the problem. See opener repair.
If the door starts but stops or reverses, it may be the sensors. See door won't close.
Older openers use outdated remote technology, and new remotes can be hard to find. That's one more reason to consider a new opener if yours is past 15 years.
