2017 GMC Acadia Key Fob Programming Guide

Quick reference

Step-by-step on-board programming

Good news! You can program new or additional key fobs for your 2017 GMC Acadia at home without any special tools, as long as you have at least one working, recognized key. If you have lost all your keys, you will need to contact a dealer or a locksmith with a scan tool to program new keys.

This procedure will program the remote functions (lock, unlock, remote start) of your new key fob. The immobilizer chip, which allows the car to start, is programmed automatically when the remote is programmed.

Follow these steps carefully:

1. Get in the driver's seat and close all doors.
2. Place your original, working key fob in the center console pocket. The pocket is located inside the center console storage area, towards the front.
3. On the driver's side door panel, press and hold the "Unlock" button.
4. While holding the "Unlock" button, press the engine "Start/Stop" button twice.
5. Release both buttons. The Driver Information Center (DIC) will display "Remote Learn Pending, Please Wait".
6. Press and hold the "Lock" and "Unlock" buttons on the new key fob simultaneously for about 15 seconds. The DIC will beep and then display "It is safe to turn off the vehicle" to confirm the new key has been programmed.
7. Press the "Start/Stop" button once to exit the programming mode.
8. Test all functions of the new key fob to ensure it is working correctly.

Battery replacement

Replacing the battery in your 2017 Acadia key fob is simple and requires only a small flathead screwdriver and a new CR2032 battery.

1. Press the button on the side of the fob to release the emergency key blade.
2. Use the key blade or a small screwdriver to carefully pry the two halves of the fob apart. There is a small slot at the top where the key blade was.
3. Carefully separate the two halves of the key fob.
4. Note the orientation of the old battery and remove it. The positive (+) side should be facing up.
5. Insert the new CR2032 battery with the positive (+) side facing up.
6. Snap the two halves of the key fob back together until you hear a click.
7. Re-insert the emergency key blade.

Where to buy a replacement fob

• Dealer: The most expensive option, but you are guaranteed to get a genuine OEM part. Expect to pay around $150–$250 for the fob itself, plus another $50–$100 for programming if you can't do it yourself.
• Locksmith: A professional automotive locksmith can provide you with a high-quality OEM or aftermarket fob and program it for you. This is often cheaper than the dealership, with total costs typically ranging from $100 to $200.
• Amazon/Online: The cheapest option for the fob itself, with prices ranging from $30 to $80. However, you must be careful to match the FCC ID (M3N-32337100) and part number. The quality can vary, and you will still need to program it yourself or have a locksmith do it.

If on-board programming isn't supported

While the 2017 Acadia does support on-board programming for the remote portion when you have a working key, programming the immobilizer transponder from scratch (if all keys are lost) requires a specialized scan tool. This tool communicates with the vehicle's computer to authorize a new key. Automotive locksmiths and dealerships have these tools. Expect to pay between $200 and $400 for a locksmith to come to you and create and program a new key if you have lost all of your originals.
