GM Smart Key Remote Programming (Push-Button Start Only)

Updated 2026 12 vehicles 2017–2020

This procedure covers 12 Chevrolet and GMC vehicles from 2017 to 2020. Check that yours is listed below, then follow the steps.

Need the fob itself?

Pick your vehicle to see replacement fobs on Amazon. Match the FCC ID on your old fob before you buy.

Not sure which fob is yours? Find your year below for the exact FCC ID and part number.

If your GMC has a regular key ignition, the remote can't be programmed at home — an automotive locksmith or dealer must do it. If it has push-button start with a smart key, you can program it yourself: use Method A with two working smart keys, or Method B with one or none.

Before you start

  • All smart keys — working and new — with you
  • Engine off

Method A — with two working smart keys

  1. 1Remove the emergency key blade from one of the working smart keys.
  2. 2Place both working smart keys in the cupholder.
  3. 3Insert the emergency key blade into the driver's-door lock cylinder and turn counterclockwise to unlock five times within 10 seconds. The Driver Information Center shows READY FOR REMOTE #2.
  4. 4Place the new smart key in the transmitter pocket — center-console storage for Cadillac, front cupholder for Chevrolet, GMC, and Buick.
  5. 5Press ENGINE START/STOP. When recognized, the display is ready for the next key.
  6. 6Take the key out and press Lock or Unlock on it.
  7. 7To add another key, repeat the last three steps. When done, press and hold ENGINE START/STOP about 12 seconds to exit.

Method B — with one or no working smart key

Takes about 30 minutes and isn't available in Canada. With no working key, have the new key's emergency blade cut by a locksmith first.

  1. 1Remove the key blade from your existing or new smart key.
  2. 2Insert it into the driver's-door lock cylinder and turn counterclockwise to unlock five times within 10 seconds. The display shows READY FOR REMOTE.
  3. 3Wait about 10 minutes until the display reads PRESS ENGINE START BUTTON TO LEARN, then press ENGINE START/STOP. The display shows REMOTE LEARN PENDING.
  4. 4Repeat that sequence two more times. After the third, all previously known keys stop working and the display shows READY FOR REMOTE #1.
  5. 5Place the new smart key in the transmitter pocket, press ENGINE START/STOP, then take it out and press Lock or Unlock.
  6. 6To add another key, repeat the last step's actions, then press and hold ENGINE START/STOP about 12 seconds to exit.

Which fob does your vehicle take?

These steps program a fob to your car — they can't tell you which fob to buy, and one that isn't the right part for your vehicle will not pair no matter how carefully you follow them. Find your vehicle below: tap your year for the exact fob it takes — FCC ID, OE part number and battery — or "Shop fobs" to browse replacements for that model.
