2017 GMC Terrain Key Fob Programming

Updated 2026 Programming, battery & replacement fob

You can program a 2017 GMC Terrain key fob yourself in a few minutes using a working key or remote, no dealer visit needed. Follow the steps below, then check the battery and the correct replacement fob (with FCC ID and part number) if you need a new one.

On this GM vehicle you can add a new key yourself using a key that already starts the engine. It adds keys without erasing the ones you have. The new key must be cut first.

Before you start

  • A key that already starts the engine
  • Your new key, already cut
  1. 1Insert the original, already-programmed key and start the engine.
  2. 2After it starts, turn the key off and remove it.
  3. 3Within 10 seconds, insert the new key and turn it to ON (don't start the engine).
  4. 4The security light goes out once the key is programmed (it can be too quick to see). No security light? Wait 10 minutes and 45 seconds.
  5. 5Repeat from step 1 for additional keys.

Photos show the OEM part for each number listed. Aftermarket replacements sold online are often slightly different in appearance — the FCC ID, not the shape, is what determines whether a fob will work with your car.

2017 GMC Terrain key fob battery

Your 2017 GMC Terrain key fob uses a CR2032 3V lithium coin cell. A fresh one typically lasts 3–5 years.

How to replace the battery

  1. 1 Slide the release latch and pull the metal emergency key out of the fob.
  2. 2 Use that key (or a coin) to pry the two halves apart at the seam.
  3. 3 Lift out the old coin cell — note which side faces up.
  4. 4 Drop in the new battery the same way (printed + side usually faces the back cover).
  5. 5 Press the case back together until it clicks, then test lock/unlock and push-to-start.

Battery tips

  • Use a fresh, name-brand 3V lithium cell — bargain cells drain quickly.
  • Even with a dead fob battery you can usually still start the car by holding the fob against the start button — check your owner's manual.
  • If the fob still won't work after a new battery, it may need re-syncing or programming.
