Garage door symptoms
The keypad outside my garage stopped working
A garage door keypad that stops working usually comes down to a weak battery, rain inside the case, or a code the opener no longer recognizes. Start with the battery; if the keys light but every code is ignored, the keypad needs reprogramming or replacing.

Get inside another way, then look at the keypad in daylight
Use a handheld remote, a car button or the entry door so nobody stands in the Portland rain punching codes. Then open the keypad cover and see whether the keys light up when pressed, because a dark keypad and a lit one that gets ignored lead to different fixes. Tell us which one you have when you call.
Likely causes, most common first
A tired battery heads the list, followed by water in the case and a pairing the opener has lost.
- Most common
The battery is worn out or chilled
The sign: The backlight is dim, slow to wake or dark, and the keypad behaves worse on cold mornings than on mild afternoons.
The fix: Install a fresh battery of the type shown inside the case, clean the contacts, and replace the keypad if corrosion has eaten into them. Garage Door Remotes, Keypads and Smart Controls, from $89
- Common
Water got inside the case
The sign: Some numbers stop responding, the keys light unevenly, fog or droplets sit behind the cover, or the battery terminals carry green or white crust.
The fix: Dry and clean a keypad that only got damp, or replace it once the circuit board or contacts have corroded. Garage Door Remotes, Keypads and Smart Controls, from $89
- Common
The PIN changed or the opener forgot the keypad
The sign: The keys light and beep as usual, yet no code moves the door, often after an outage, a new opener, or someone in the house changing the PIN.
The fix: Pair the keypad with the opener again and set a new PIN, then store that code somewhere away from the garage. Garage Door Remotes, Keypads and Smart Controls, from $89
- Common
A vacation lock is shutting out wireless controls
The sign: The handheld remotes are ignored too; on LiftMaster and Chamberlain the wall button still works, and on some Genie consoles the red backlight has gone out.
The fix: Switch the vacation or lock setting off at the wall control, then try the keypad again. Garage Door Remotes, Keypads and Smart Controls, from $89
- Less common
The keys are worn or sticking
The sign: The digits you use most look faded or polished, one key needs a hard press, or a key stays down after you let go.
The fix: Replace the keypad, because worn keys also tell a stranger which numbers are in your code. Garage Door Remotes, Keypads and Smart Controls, from $89
- Less common
The keypad does not suit a newer opener
The sign: The keypad ran the old opener for years and will not pair with the replacement, however carefully the steps are followed.
The fix: Fit a keypad built for the new opener, or a universal keypad that lists it as compatible. Garage Door Opener Installation, from $549
What you can safely check in two minutes
These checks happen at the keypad and the wall control, and none of them needs anything beyond a fresh battery.
- Press any key and watch the backlight. No glow at all means the battery comes first.
- Open the battery door and look for fog, droplets or crusted terminals inside the case.
- Look at the wall control for a lock or vacation setting that has been switched on.
- Try a handheld remote. If remotes fail as well, the trouble sits at the opener rather than the keypad.
- Enter the code slowly and finish with the Enter or open key if your keypad has one, since many ignore the digits without it.
- Check the keys in daylight. Faded numbers or a key that sticks point to a worn pad.
Why a Portland keypad has a harder life than a remote
A keypad spends every wet month outdoors, so moisture and cold do damage that a remote riding in a pocket never sees.
Rain falls at Portland International Airport on roughly 157 days in a typical year, and December averages more than 19 wet days by itself. Wind pushes that rain sideways past a cover that is cracked, missing or propped open, and the water settles on the battery terminals first.
Mounting position matters as much as weather. A pad on an exposed jamb, or beside an alley-facing door like the rear garages around Orenco Station in Hillsboro, takes far more rain than one tucked under an eave, a porch roof or deep trim.
Faded keys give your code away
A keypad with worn keys is a security problem as well as a nuisance, because the digits in your PIN are exactly the ones that wear.
Anyone walking up the driveway can spot four polished keys, and four different digits can only be arranged 24 ways. If yours shows that pattern, change the code now and plan on a new keypad.
Many LiftMaster and Chamberlain keypads also accept a temporary PIN for a dog walker, a house sitter or a contractor, which saves handing out the code you use every day.
What reprogramming or replacing a keypad involves
A keypad visit usually ends one of two ways: a new battery and a fresh pairing, or a new keypad mounted where weather reaches it least.
We confirm the keypad and opener share a compatible radio system, set the PIN you choose, and make sure your remotes and car buttons still work afterward. When the old pad sat where rain sheets down the jamb, the new one goes a little higher or under the trim.
Programming steps differ from brand to brand, and the step-by-step programming guide covers each major one for anyone who wants to try first.
Keypad stopped working: common questions
Why did my garage keypad stop working right after I changed the battery?
Most often the new battery went in backward, a contact got bent, or the cell itself is old stock. Check that it sits flat with the polarity marks matched, then try your code. If the keys light but the door still ignores you, pair the keypad with the opener again, since a long stretch without power can leave it out of sync.
How do I tell if my garage door keypad is locked out or just broken?
A handheld remote tells you: if it is ignored too, the opener is usually locked out, and if it works, the keypad is at fault. On many openers, a lock or vacation setting at the wall control blocks remotes and keypads while the wall button keeps working, and switching it off solves it. When only the keypad fails, look at its battery, its pairing or the keypad itself.
Can Portland rain ruin a garage door keypad for good?
It can, once water reaches the circuit board. Light moisture on the terminals often dries out and cleans up, and the keypad recovers. Green crust on the board, keys that respond at random, or fog that returns after drying all mean corrosion has spread, and a new keypad is the reliable fix. A closed cover and a sheltered spot slow that down.
What should I do if I forgot my garage keypad code?
Set a new PIN at the opener rather than guessing. On many openers you press the learn button on the motor head, then enter a new code on the keypad within a short window, which replaces the forgotten one. The exact sequence varies by brand and keypad model, so check the manual or our programming guide before climbing the ladder.
Will my old garage keypad work with a new opener?
Only if both use compatible radio systems. Keypads talk to openers by radio, and formats have changed over the years, so an older keypad may refuse to pair with a new opener, especially across brands. Check the compatibility list for the new opener before buying, or have a matching keypad brought along when the opener is installed.
Why does my garage keypad work in the afternoon but not on cold mornings?
That pattern points to a battery that is nearly spent. Cold slows the chemistry inside a cell, so an aging battery cannot deliver enough current at dawn and recovers as the day warms. Replace it before the first hard freeze, and if a new one does not end the pattern, look for moisture freezing on the terminals overnight.
