2. Step-by-Step Programming Guide

Whether you have recognized transmitters or need to start from scratch, this guide provides clear instructions for programming your 2019 GMC Acadia key fob.

2.1 Programming with Two Recognized Transmitters

If you have two working key fobs, programming a new one is relatively straightforward. Follow these steps:

Prepare: Ensure the vehicle is off, and gather all transmitters (both recognized and new).
Place Recognized Transmitters: Put the two working key fobs in the cup holder.
Access Key Lock Cylinder: Remove the cap on the driver’s side door handle to reveal the key lock cylinder.
Insert and Turn Key: Insert the vehicle key from the new transmitter into the lock cylinder and turn it counterclockwise five times within 10 seconds. The Driver Information Center (DIC) will display “READY FOR REMOTE #2, 3, 4, ETC.”
Place New Transmitter: Put the new key fob into the transmitter pocket located inside the center console storage area.
Press Start/Stop: Press the ENGINE START/STOP button. The DIC will confirm when the transmitter is learned.
Test Transmitter: Remove the key fob and press the UNLOCK or LOCK button to ensure it works.
Program Additional Transmitters: Repeat steps 3-5 for any additional key fobs.
Exit Programming Mode: Once all transmitters are programmed, press and hold the ENGINE START/STOP button for 12 seconds to exit programming mode.
Reassemble Key: Place the key back into the transmitter.

2.2 Programming Without Recognized Transmitters

If you don’t have two working key fobs, the process is more involved but still manageable:

Prepare: Ensure the vehicle is off and gather all transmitters. Note that this feature is not available in Canada.
Access Key Lock Cylinder: Remove the cap on the driver’s side door handle to reveal the key lock cylinder.
Insert and Turn Key: Insert the vehicle key into the lock cylinder and turn it counterclockwise five times within 10 seconds. The DIC will display “REMOTE LEARN PENDING, PLEASE WAIT.”
Wait 10 Minutes: Wait for 10 minutes until the DIC displays “PRESS ENGINE START BUTTON TO LEARN,” then press the ENGINE START/STOP button. The DIC will again show “REMOTE LEARN PENDING, PLEASE WAIT.”
Repeat Waiting Process: Repeat step 2 two additional times. After the third time, all previously known transmitters will no longer work.
Ready for Remote: The DIC should now display “READY FOR REMOTE # 1.”
Place New Transmitter: Put the new key fob into the transmitter pocket in the center console.
Press Start/Stop: Press the ENGINE START/STOP button. The DIC will confirm when the transmitter is learned.
Test Transmitter: Remove the key fob and press the UNLOCK or LOCK button to ensure it works.
Program Additional Transmitters: Repeat steps 4-6 for any additional key fobs.
Exit Programming Mode: Once all transmitters are programmed, press and hold the ENGINE START/STOP button for 12 seconds to exit programming mode.
Reassemble Key: Place the key back into the transmitter.

This process may take up to 30 minutes, but following these steps ensures your key fobs are correctly programmed.
