Keypad or remote not working: start where you're standing

Three places you can be when this happens: outside at the keypad, in the car with the remote, or inside at the wall button. Each one tells you something the others cannot, and the diagnosis is mostly a matter of noticing which ones still work.

The keypad is dead but the remote still works

The keypad has its own battery, usually a 9-volt behind the cover, and it is the single most common reason a keypad goes quiet. Swap it before doing anything else. If the keypad lights up but the door does not respond, the battery was low enough to light the keys and not strong enough to send. A fresh battery fixes that too.

If the keypad is lit, the battery is new, and the door still ignores it, the keypad has lost its pairing with the opener. That happens on its own less often than people think, but it happens after a power blink, which is covered below. Re-pairing is a two-minute job with the learn button on the back of the motor head, and the steps are printed inside most keypad covers.

Last on this branch: the membrane. A keypad that has been outside through fifteen DeKalb winters gets a worn rubber face, and one or two digits stop registering. If the code has a 7 in it and the 7 no longer clicks, that is the whole problem. A replacement keypad is inexpensive and, on this crew, usually a same-visit add when we are there for anything else.

The keypad works but the door does not move

Now the keypad is talking and the opener is hearing it. Something downstream is the problem, and it is usually visible from where you stand.

The opener light comes on and the motor hums but the door stays put. That is not a keypad problem. It is a stripped gear, a snapped chain, or a door that has gotten too heavy for the opener because a spring has broken. Stop pressing buttons and look at the spring above the door for a clean gap in the coil. The opener repair page covers the gear failures and the spring check that comes first on every call.

The door starts, then reverses. Sensors, or the close force setting. The keypad did its job. The won’t close guide has the sensor test.

Nothing at all happens, no light, no hum. Either the opener has lost power or it is in lockout, and both show up at the wall button, so go inside.

Inside: what the wall button tells you

The wall button is wired, not radio, so it cuts the problem in half.

If the wall button opens the door and neither the keypad nor the remote does, every radio device lost the opener at once. Two causes. The opener’s lock button, which sits on most wall consoles and silences every remote and keypad while the wired button keeps working. It gets pressed by a hip or a kid, the light on it blinks, and nobody notices the light. Press it once and try the remote. The other cause is a wiped memory, covered next.

If the wall button does nothing either, it is power or the opener itself. Check the outlet on the ceiling, then the breaker, then the GFCI in the garage, which trips in a wet spring and takes the opener with it. The opener not working guide runs the three tests in order.

After a power blink: re-pair before you replace

A surprising number of “the keypad and remote both died” calls in DeKalb come the day after a storm or a utility switch. A power interruption can clear the code memory on some openers, especially older ones, and every device that was paired to it drops off at once. The devices are fine. The opener forgot them.

The fix is the learn button. Press it once, then press the remote’s button within thirty seconds. Repeat for each remote. For the keypad, press learn, enter the code, press the enter key. If the door light blinks, it took. The exact sequence varies by brand and is on the label under the light cover. Holding the learn button too long, more than six seconds on most units, erases every device, so a short press is the rule.

Only replace a remote or keypad after a fresh battery and a re-pair both fail. Most of the ones thrown away in this town were working.

Why does the keypad stop working in January?

Because a lot of DeKalb garages are detached, off the alley, and as cold as the weather. Alkaline batteries lose a large share of their output below freezing, and a 9-volt that was marginal in November is dead the first morning it hits zero. The remote in the car has the same problem after a night outside. If the keypad only fails on the coldest mornings and comes back by afternoon, that is the battery, not the keypad. A fresh lithium 9-volt in the fall handles the cold far better than alkaline and is the cheapest fix in this whole guide.

Cold also thickens the grease in an older opener’s gearbox, which is why the same January week brings keypad calls, opener calls, and spring calls together. If the keypad works and the opener strains, the keypad was never the problem.

Older opener, new keypad: the add-on receiver

Openers from before the mid-1990s use a different radio system than anything sold today, and a current keypad will not pair to them. That is not a reason to replace the opener if it runs fine. An add-on receiver wires to the opener’s wall button terminals and brings its own keypad and remotes, and it works on nearly any unit with a motor still turning. It is a common install on the older detached garages around Sycamore and the near-north side of DeKalb.

The line where a new opener wins instead is the one on the opener repair page: no safety sensors, a stripped gear on a unit past fifteen, or a chain drive loud enough to bother the neighbors across the alley.

What does it cost to fix a keypad or remote in DeKalb?

A battery costs a battery. A re-pair is free if you do it and folded into the visit if we do. A replacement keypad or remote is priced as a part, and an add-on receiver a bit more. When the problem turns out to be the opener, repairs land between $95 and $240 for gears, trolleys, sensors, and boards, and a new opener installed runs $380 to $700. The cost page has the whole table.

Have three answers ready when you call: does the wall button work, does the remote work, and did anything change, like a storm or a new battery. Those three usually put the fix on the first visit.
