Garage Door Remote or Keypad Not Working: Quick Checks

A remote that quits in the driveway on a January morning is one of the most common garage door complaints, and it's usually one of the cheapest to fix. Work through these checks in order. None of them require touching the springs, cables, or door hardware.

Step 1: Test the wall button

Press the wall control inside the garage.

• The wall button works. The opener has power and the motor runs, so the problem is the remote, the keypad, or the radio signal. Keep going.
• The wall button doesn't work either. Check that the opener is plugged in and the outlet has power. If the opener hums but the door doesn't move, that's a different problem, often ice, a broken spring, or the opener itself. See opener straining in winter or door won't open in cold weather.

Step 2: Turn off lock (vacation) mode

Many wall controls have a lock button that blocks remotes and keypads while the wall button keeps working. It's easy to bump by accident.

On Chamberlain and LiftMaster openers, Chamberlain's support pages list these signs that lock is on:

• The opener lights flash twice when you press a remote button
• The light on the wall control flashes continuously

To turn it off, press and hold the lock button until the light stops flashing, then test the remote. Genie's troubleshooting guide for several of its models says the same thing in its own words: confirm the vacation lock switch on the wall console is off. Locked out with no other way in? Chamberlain notes you'll need to get into the garage through another door to turn lock mode off.

Step 3: Replace the battery

A weak battery is the most likely cause of a remote that works sometimes, works only up close, or stopped working overnight.

• Remotes: Chamberlain's remote troubleshooting calls for a CR2032 3V coin battery in many of its current remotes, and Genie uses the same type in its G3T remote. Check your remote's battery compartment before you buy.
• Keypads: Chamberlain says most of its wireless keypads take a 9V alkaline battery. LiftMaster's keypad instructions say to replace it when the keypad light becomes dim or doesn't light up.

While the cover is off, check the battery contacts for corrosion and match the + and - markings.

Why cold mornings make it worse

Energizer's technical guide for alkaline batteries explains that cold slows the chemical reactions inside the battery, so it can't deliver its full power. Nothing is permanently lost, and the battery recovers once it warms up. In practice, a remote with an aging battery may work fine in October and quit when it's been sitting in a cold car overnight. If a remote works again after a few hours indoors, a weak battery is the likely cause, so replace it.

Outdoor keypads take the full Minnesota winter. Chamberlain lists the operating range of its CH348 wireless keypad as -4°F to 149°F, and Twin Cities winters regularly get colder than that. If your keypad gets flaky on the coldest days, check your model's manual for its rated range and use the remote or the wall button until it warms up.

Step 4: Check the range and rule out interference

Stand right under the opener and press the remote. Then back up and try again from a few spots.

It works up close but not from the driveway? Something is weakening the signal. Chamberlain and Genie both name some LED and energy-efficient light bulbs as a common source of radio interference. To test, remove the bulbs from the opener (let them cool first) and try the remote from farther away. If the range improves, the bulbs were the problem. Chamberlain says to switch to a different bulb type or one made to work with garage door openers.

Genie's guide also suggests:

• Checking for anything you recently added in or near the garage that could interfere
• Repositioning the opener's antenna (the short wire hanging from the motor unit) so it hangs down and isn't damaged

Step 5: Reprogram the remote or keypad

If a fresh battery and a range test don't fix it, the opener may have lost the remote's code. Chamberlain notes a common cause: someone pressed and held the learn button on the opener too long, which erases every programmed remote and keypad at once.

Most openers are programmed by pressing the learn (or program) button on the motor unit, then pressing the remote button or entering the keypad PIN within about 30 seconds. The details depend on the brand and model:

• Chamberlain's programming guides say the color of the learn button tells you which method and which remotes are compatible.
• Genie's instructions differ between newer openers (a program button and blue and purple lights) and openers made from 1995 to 2011 (a learn code button and a red light).
• Built-in car buttons have their own steps. Check your vehicle's manual.

Use the instructions for your exact opener model, usually on a label on the motor unit or in the owner's manual. Stand on a sturdy step ladder to reach the button, keep clear of the moving door, and watch the door until it fully stops.

If you lost a remote or just moved in, erase all remotes and keypads from the opener and reprogram the ones you have. Genie and Chamberlain both list this step. Erasing clears every device, so have all your remotes and the keypad on hand before you start.

When a new remote won't program at all

Older openers may not work with newer remotes. LiftMaster's universal keypad instructions say its products are meant for openers made after 1993 that have safety sensors, and that an opener without working sensors doesn't meet current federal safety rules and should be replaced. If your opener is that old, ask a technician about replacing it.

When to call a technician

Request help if:

• Every remote and keypad stopped working at the same time, and lock mode and batteries check out. Genie says that can mean the opener's circuit board needs to be replaced.
• The wall button also stopped working, and the opener has power.
• The door opens or closes on its own. Genie lists a stuck button and shorted wall-control wiring among the causes.
• The opener lights flash 10 times and the door won't close. On Chamberlain openers that points to the safety sensors. See sensor light blinking.
• The door is stuck open and you can't close it safely. See garage door stuck open and choose "ASAP" when you request help, or go to emergency garage door repair.

A technician can diagnose the receiver or logic board, program remotes, keypads, and car buttons, and tell you whether repair or a new opener makes more sense. See opener, remote, and keypad repair.
