How do I program HomeLink in my car to a Security+ 3.0 garage door opener?

Security+ 3.0 is Chamberlain Group's newest opener protocol, rolled out on LiftMaster and Chamberlain openers in late 2025. You can identify it by the white learn button on the opener. The white button replaced the yellow button that marked Security+ 2.0 openers.

Programming HomeLink to a Security+ 3.0 opener is not the same as programming it to an older rolling-code opener. The old process used the learn button on the motor head. With Security+ 3.0, you do NOT press the learn button on the opener at all. Instead, you use the Security+ 3.0 handheld remote transmitter to train HomeLink directly. Here is the correct process.

What you need before you start

Before you start, confirm a few things:

White learn button: The opener's learn button must be white. If it is yellow, purple, or any other color, use the standard rolling-code programming process instead (press and hold the HomeLink button until it blinks twice, then go to the opener and press the learn button).

HomeLink generation: HomeLink versions 4, 5, and 6 are all compatible with Security+ 3.0. These versions cover most vehicles manufactured in 2016 and later. Check your vehicle's owner manual to find your HomeLink version, or look up your car's model year at homelink.com. Compatibility can vary by vehicle make and model even within these versions.

Security+ 3.0 remote transmitter in hand: The pairing process uses your handheld remote, not the learn button on the opener. Your Security+ 3.0 remote must already be paired to the opener before you begin HomeLink setup.

Step-by-step programming process for Security+ 3.0

This process is published by Moving Up Garage Doors and confirmed against HomeLink support documentation. Note: do NOT use the white learn button on the opener at any step. Use the handheld remote transmitter instead.

1. Make sure your Security+ 3.0 remote is already paired to the opener and working before you start HomeLink setup.
2. Sit in your car with the Security+ 3.0 handheld remote in hand. You need to be close enough to the HomeLink button in the car for the remote signal to reach it reliably.
3. Press and release the HomeLink button you want to program in your car. Confirm the HomeLink indicator light begins to flash slowly.
4. While the HomeLink LED is flashing slowly, hold the Security+ 3.0 handheld remote very close to the HomeLink button (a few inches away). Press and hold the remote button that already operates your door.
5. Keep holding the remote button until the HomeLink indicator changes from a slow blink to a rapid flash. Then release all buttons.
6. Test the programming: press and hold the newly programmed HomeLink button. The door should begin to move. On some vehicles, the first press arms the system and the second press operates the door; this is normal behavior.

If the indicator stays blinking slowly and does not switch to a rapid flash, move the remote closer to the HomeLink button and try again. The remote must be just a few inches from the HomeLink button for the signal to transfer reliably.

If the indicator stays blinking and does not go solid, the Bluetooth handshake did not complete. The most common reason is distance. Move the car closer to the opener (parking inside the garage with the door up is ideal) and try again. On some vehicles, turning the ignition fully to the "on" position rather than "accessory" mode also helps, since HomeLink on some cars draws more Bluetooth power in full run mode.

Troubleshooting HomeLink Security+ 3.0 pairing problems

HomeLink keeps blinking slowly and does not switch to rapid flash: - The remote is too far from the HomeLink button. Move the remote to within a few inches of the HomeLink button and try again. - Your HomeLink version may not be compatible with Security+ 3.0. HomeLink versions 4, 5, and 6 are generally supported; older versions may not work. Check homelink.com for a compatibility lookup by vehicle make, model, and year.

You programmed it but the door does not respond: - The pairing may not have completed. Repeat the process and confirm the HomeLink indicator switched to a rapid flash before you released the buttons. - Some vehicles require pressing the HomeLink button twice to operate the door on the first use after programming; this is normal.

Your vehicle is a 2025 model and HomeLink will not pair at all: - Some 2025 vehicle models shipped with HomeLink firmware that needed an over-the-air update to enable Security+ 3.0 pairing. Check with your dealership whether a HomeLink firmware update is available for your vehicle. This is a quick dealership service, not a recall.

You have a car built before 2016 with older HomeLink: - HomeLink versions older than version 4 may not pair with Security+ 3.0. In this case, you cannot use the car's built-in HomeLink with your new white-button opener. You can still use the handheld remote that came with the opener. Alternatively, use the myQ app on your phone for door control from the car. Chamberlain also sells a HomeLink Compatibility Bridge (HOMELINK RPTRMC) that can bridge older vehicles to Security+ 3.0 openers.

Does Security+ 3.0 work with older HomeLink programming methods?

No. The classic HomeLink rolling-code programming sequence (hold the HomeLink button near the remote, then press the learn button on the opener) only works with openers using 315 MHz or 390 MHz radio frequency. Security+ 3.0 does not transmit on those frequencies for accessory pairing. With Security+ 3.0, you always use the handheld remote to train HomeLink, not the learn button on the motor head.

This is also why Security+ 3.0 is not compatible with older universal remotes, ratgdo, or the wireless pairing mode of Konnected blaQ. Note that Konnected blaQ in wired contact-closure mode does work with Security+ 3.0 openers for basic open/close control.

Security+ 3.0 versus Security+ 2.0: what changed for accessories

The shift from Security+ 2.0 to Security+ 3.0 affects all wireless accessories, not just HomeLink. Here is a quick comparison so you know what works and what does not with the white-button opener.

Feature	Security+ 2.0 (yellow button)	Security+ 3.0 (white button)
Radio frequency	315 or 390 MHz rolling code	BLE only, no RF open/close signal
Older universal remotes	Compatible	Not compatible
ratgdo / Konnected blaQ	Compatible	Not compatible (as of 2026)
HomeLink	Works with all generations	Requires HomeLink 4, 5, or 6 (most 2016+ vehicles)
myQ app	Works	Works (required for setup)
Amazon Key In-Garage Delivery	Works	Works
Third-party smart home (Home Assistant, Hubitat)	Works via ratgdo	No local integration currently available

The table explains why many homeowners who upgraded their opener to a new white-button LiftMaster or Chamberlain suddenly found that their car's HomeLink, their Home Assistant integration, or their universal remote stopped working. The accessories themselves are not broken. They just use an older protocol that Security+ 3.0 no longer accepts.

For HomeLink specifically, the path is clear: vehicles with HomeLink versions 4, 5, or 6 (most 2016 and newer) pair using the handheld remote procedure above; older vehicles without a compatible HomeLink version use the myQ app instead. The experience is the same once set up, just a different initial pairing process.
