Chevrolet Smart Key Programming With the Start/Stop Button

Updated 2026 6 vehicles 2019–2021

This procedure covers 6 Chevrolet vehicles from 2019 to 2021. 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 Chevrolet has push-button start with a smart key, you can program it yourself: Method A with two working smart keys, Method B with one or none (up to 8 total).

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 front cupholder of the center-console storage area, buttons facing down.
  3. 3Insert the emergency key blade into the driver's-door lock cylinder and turn counterclockwise to unlock five times within 10 seconds. The display shows READY FOR REMOTE #2.
  4. 4Place the new smart key in the transmitter pocket (front cupholder for Chevrolet and Buick).
  5. 5Press ENGINE START/STOP. When recognized, the display is ready for the next key.
  6. 6Take the key out and press UNLOCK. To add more, repeat the last three steps, then press and hold ENGINE START/STOP about 12 seconds to exit.

Method B — with one or no working smart key

About 30 minutes; not available in Canada. With no working key, have the new blade cut by a locksmith first.

  1. 1Remove the key blade from your existing or new smart key and insert it into the driver's-door lock cylinder. Turn counterclockwise to unlock five times within 10 seconds. The display shows REMOTE LEARN PENDING.
  2. 2Wait 10 minutes until it shows PRESS ENGINE START BUTTON TO LEARN, then press ENGINE START/STOP (it shows REMOTE LEARN PENDING again).
  3. 3Repeat that sequence two more times. After the third, all previous keys stop working and the display shows READY FOR REMOTE #1.
  4. 4Place the new smart key in the transmitter pocket (front cupholder), press ENGINE START/STOP, then take it out and press UNLOCK.
  5. 5To 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.
