Before you buy a replacement remote or keypad for a LiftMaster, Chamberlain or Craftsman opener, climb a step stool and look at the motor head. The small square or round button marked LEARN is colour-coded, and that colour is the only reliable way to know which remote will talk to your opener. Two openers with the same brand name can need completely different remotes. Two openers with different brand names can take the same one.
This guide is about buying the right remote. If you already have a remote that stopped working, start with our remote not working checklist instead.
Why the learn button colour decides which remote you buy
The colour tells you which radio frequency and which code system your opener listens for. A replacement remote has to match both, so the colour, not the brand name on the case, decides what you buy.
Frequency alone isn't enough. Green and red/orange buttons are both 390 MHz, but green openers use a fixed "Billion Code" and red/orange openers use Security+ rolling code. A remote built for one won't pair with the other even though they share a frequency. That trips up a lot of online orders.
Where to find the button
Chamberlain Group's support article says the learn button sits on the same side of the opener as the wires from the wall control and the safety sensors. On many models it's behind the light lens or a small side cover. You may need a flashlight; the button is small and the label is easy to miss.
Write down the opener's model number from the label while you're up there. If the button colour is faded or you're not sure, the model number settles it.
Learn button colour chart (LiftMaster, Chamberlain, Craftsman)
This table is built from Chamberlain Group's own learn-button identification article, which covers all three brands because they come from the same manufacturer.
| Learn button | Code system | Frequency | Years (per Chamberlain Group) |
|---|---|---|---|
| White, round | Security+ 3.0 | Bluetooth LE Long Range, 2.4 GHz | 2025 to present |
| Yellow, round, with Step Saver label | Security+ 2.0 | 315 or 390 MHz | 2022 to 2025 |
| Yellow, round | Security+ 2.0 | 310, 315 and 390 MHz | 2011 to 2022 |
| Purple (may look brown) | Security+ rolling code | 315 MHz | 2005 to 2014 |
| Red/orange | Security+ rolling code | 390 MHz | 1997 to 2004 |
| Green | Billion Code (fixed) | 390 MHz | 1993 to 1997 |
| Blue | Security+ rolling code | 433 MHz | 1997 to 2014 |
| Square yellow, white or grey with DIP switches | DIP switch | No longer supported | Before 1993 |
The year ranges overlap because production changed over model by model, not on one date. Chamberlain Group's own pages also disagree by a year in places: the colour article starts green at 1993, while the remote compatibility chart says 1994. Treat the years as a rough guide and trust the colour.
A blue button is the odd one out. It runs on 433 MHz, which no other row in the chart shares, so bring us the model number before buying anything for it.
Brown is purple, orange is red
Probably not. Chamberlain Group notes that purple buttons can fade to look brown and red ones can look orange. Brown is treated as purple: 315 MHz Security+ rolling code.
The white learn button: Security+ 3.0
The newest openers have a round white learn button. That's Security+ 3.0, and it is a clean break from everything before it. LiftMaster's product page for the L993S 3-button remote lists it as "Security+ 3.0, BLE LR 2.4 GHz, E Code (White Button)" and says it controls up to three Security+ 3.0 openers. It doesn't list any older button colours.
No. A white learn button means Security+ 3.0, which uses Bluetooth Low Energy Long Range on 2.4 GHz. The older yellow-era remotes and keypads are not listed as compatible with it, so you need a remote that names Security+ 3.0 or the white button on the package.
LiftMaster also makes a remote that covers both generations. The L993M lists Security+ 3.0 (white button) plus Security+ 2.0 on 315 MHz and 390 MHz (yellow button), and LiftMaster says it works with Chamberlain, LiftMaster and most Craftsman openers made after 1997 with safety sensors. That makes it the practical pick for a household with one new white-button opener and one older yellow-button opener. It runs on a single CR2032 coin cell, and LiftMaster quotes up to 1,300 ft of range, conditions permitting.
Which remote or keypad matches each learn button colour
These are current models listed on the LiftMaster and Chamberlain compatibility charts. Charts change as models are replaced, so check the box or the manufacturer's chart before you buy.
| Your learn button | LiftMaster options | Chamberlain options |
|---|---|---|
| White only | L991S, L993S remotes; L979S keypad | CH161, CH163, CH382 remotes; CH148 keypad |
| White, yellow, purple or red/orange | L993M remote; L979M keypad | CH361, CH363 remotes; CH348 keypad |
| Any colour, including green | L992U universal remote; L979U universal keypad | CHU62 universal remote; CHU48 universal keypad |
Older remotes you may still find in drawers or online, like the 893MAX, 890MAX, 893LM and 371LM, now sit in the legacy section of LiftMaster's chart. The chart's advice for discontinued accessories is to replace them with the most current universal model. The 371LM is a purple-only (315 MHz) remote; it will not run a yellow or white opener.
A quick buying rule
- One opener, white button: a white-only remote is simplest.
- Mixed openers (say, a new one in the garage and an older one on a second door): buy a model listed for every colour you own.
- Green button: only the universal models on the charts above list green. At that age, read the next section before spending money on remotes.
Genie, Hörmann and other openers without colour codes
The colour system belongs to Chamberlain Group brands. Other makers do it differently.
Genie. Do Genie openers use learn button colours? No. Genie does not use the colour system. Genie Intellicode remotes are dual 315/390 MHz and work with Genie Intellicode and Overhead Door CodeDodger openers from 1995 on; older Genie units use 390 MHz DIP-switch remotes. Genie's current Intellicode remotes include the G3T-BX and G1T-BX, and Genie lists them as dual 315/390 MHz "auto-seek" models that find the right frequency on their own.
Hörmann. Hörmann's BiSecur radio runs on 315 MHz in North America and 868.3 MHz in Europe, and the two aren't cross-compatible. If an opener came over with a European import, a North American remote won't work with it. Read the frequency on the opener label before ordering.
When a new remote isn't worth buying
If your opener has DIP switches instead of a learn button, stop before ordering. DIP-switch openers were made before 1993, and Chamberlain Group lists that technology as no longer supported for new accessories. At that age, replacing the opener usually makes more sense than hunting for a remote.
Green-button openers date from the mid-1990s. A universal remote will still pair with one, but at 30-odd years old the opener itself is on borrowed time. Signs like grinding, reversing for no reason or a door that stalls halfway are covered in our guide to telling whether an opener is dying. If you're replacing it anyway, the new opener comes with its own remotes. You can compare current wall-mount, belt and chain units on our LiftMaster opener page and Chamberlain opener page.
One more case: if the remote you bought matches your learn button colour and still won't pair, the problem is usually in the opener, not the remote. Common causes are a logic board fault, a lockout setting on the wall control, or a damaged antenna wire. That's an opener repair job.
Learn button colour checklist before you order
- Find the learn button and note the colour and shape (round or square).
- Write down the opener model number from the label.
- List every opener and gate the remote needs to run, with each one's colour.
- Pick a remote that lists every colour you wrote down.
- Keep the receipt until the remote is paired and working.
