Garage Door Remote Only Works Up Close
If your garage door remote only works when you're a few feet away, it's almost always a weak battery, a blocked or misaligned antenna wire on the opener, or nearby radio interference (often an LED bulb). Start with a fresh remote battery, make sure the thin antenna wire hanging from the opener is fully extended and undamaged, and swap out any LED or CFL bulbs in the opener for an LED rated "garage door opener safe." That trio fixes the large majority of short-range problems.
Step by step
-
1
Replace the remote battery first
A dying battery is the number-one cause of shrinking range. Pop open the remote (usually a small slot for a coin or screwdriver), note the battery type (commonly a CR2032 or CR2016 coin cell, or a 23A/27A for older clickers), and drop in a fresh one. Wipe the contacts with a dry cloth while you're in there. Test from your normal distance before moving on.

Check and extend the opener's antenna wire
Look up at the motor unit on your ceiling. A thin wire, usually 6 to 12 inches long, should be hanging straight down. This is the antenna. If it's curled up, taped to the housing, tucked away, or chewed/broken, range drops dramatically. Gently straighten it so it hangs freely toward the floor. If it's damaged, that's a quick fix a tech can re-attach.

Hunt down LED or CFL bulb interference
This trips up a ton of homeowners. Cheap LED and CFL bulbs broadcast radio noise that drowns out your remote's signal, and it often only matters at distance. Try removing the opener's bulbs entirely and test the remote from the curb. If range jumps back, replace them with LED bulbs specifically labeled "garage door opener rated" or vibration/interference-resistant.

Rule out other radio interference
Newer LED light fixtures, smart-home devices, low-voltage transformers, security systems, and even a neighbor's electronics can flood your opener's frequency (315 or 390 MHz on most units). Note whether the problem started after you installed something new. Unplug or power down recent additions one at a time and re-test to find the culprit.

5
Re-program the remote to the opener
A remote that's partially lost its sync can act flaky and short-range. Find the "Learn" button on the motor unit (often behind the light lens), press it, then press your remote button within 30 seconds until the opener lights blink or it clicks. Re-pairing gives you a clean, strong connection. Check your opener's manual for the exact sequence.

6
Inspect the wall button and wiring
If the wall-mounted button works perfectly but remotes are weak, the issue is on the radio side (battery, antenna, interference) and not the opener's motor. That's useful information. If even the wall button is iffy, you may have a logic-board or receiver problem that's worth having a pro look at.
When to call a pro
If you've swapped the battery, freed the antenna wire, removed bulb interference, and re-programmed the remote but range is still poor, call a pro to test the opener's receiver and logic board, or to install an external antenna extension kit.

Why does my garage door remote only work right under the door?
Almost always a weak remote battery or a problem with the opener's antenna, the thin wire that hangs down from the motor unit. If the wire is curled up, broken, or tucked away, your signal can't reach. LED bulb interference is the third big culprit and often the sneakiest, since it only kills range at a distance.
Can LED light bulbs really mess up my garage door remote?
Yes, very much so. Many inexpensive LED and CFL bulbs emit radio interference on the same frequencies garage openers use. The fix is to remove the opener's bulbs and test, then replace them with LEDs specifically rated as "garage door opener safe" or interference-resistant. It's one of the most common and most overlooked causes of short range.
How do I know if it's the battery or the antenna?
Start with the battery since it's cheap and takes a minute. If a fresh battery doesn't restore your range, look at the antenna wire on the opener: it should hang straight down, fully extended, and undamaged. If both check out and range is still short, suspect bulb or radio interference next.
How much does it cost to fix a short-range garage remote?
Most fixes are nearly free, a battery runs a few dollars and straightening the antenna costs nothing. A replacement remote is typically $30 to $60. If a technician needs to install an antenna extension kit or repair the opener's receiver, expect a service call in the range of roughly $90 to $200 depending on parts and your area.
