Park outside, train the chosen HomeLink button from the remote held 3–7 cm away, and use the motor-head Learn button if the indicator changes to a rapid green flash.
Check that your vehicle has it.
The 2025 CX-30 manual marks HomeLink as a some-models function; the physical HomeLink buttons on the mirror are the controlling equipment check.

Know what kind of control to look for.
This original category diagram is an orientation aid, not a picture of your exact trim. Use the written labels and your vehicle manual to identify the real control.
Step by step.
- 01
Park the CX-30 outside the garage, switch vehicle power on as instructed, and keep people and objects clear of the door.
- 02
Press and release the HomeLink button you want to program.
- 03
Hold the original handheld transmitter 3–7 cm from the HomeLink surface and press its button until the HomeLink indicator changes from amber flashing to green.
- 04
Test the programmed HomeLink button; a slowly flashing green indicator generally completes a fixed-code setup.
- 05
If the indicator flashes green rapidly, press the opener motor's Learn or Smart button and, within 30 seconds, press-hold-release HomeLink for two seconds up to three times.
Important limits
- Program only while parked outside so an unexpectedly moving garage door cannot strike the vehicle.
- The rolling-code Learn button is usually on the garage-door motor housing and may require a ladder; follow the opener manufacturer's safety instructions.
- Do not erase all HomeLink channels when you intend to replace only one programmed button.
Quick checks.
- ✓If the indicator never turns green, change the handheld transmitter distance slightly and confirm its battery works.
- ✓If training succeeds but the door does not move, complete the rolling-code Learn-button sequence.
- ✓If the 30-second Learn window expires, press the opener's Learn button again and repeat the two-second HomeLink presses.
