2019 GMC Acadia Key Fob Programming

Quick reference

Step-by-step on-board programming

The 2019 GMC Acadia supports on-board programming, meaning you can program new key fobs yourself without a special scan tool. You will need one working key fob to begin.

1. Enter the vehicle and close all doors.
2. Insert the working key into the ignition and turn it to the "ON" position (do not start the engine).
3. Within 5 seconds, turn the key to the "OFF" position, then turn it back to "ON".
4. The vehicle's display screen should show "REMOTE LEARN PENDING" or a similar message.
5. Press and hold the LOCK and UNLOCK buttons simultaneously on the new key fob you wish to program. Hold them until the vehicle honks or the display indicates programming is successful (approximately 15-30 seconds).
6. Repeat step 5 for any additional key fobs you wish to program, including your original working fob if you want to ensure it's still recognized.
7. Once all fobs are programmed, turn the ignition to the "OFF" position and remove the key. Test all fobs to ensure they function correctly.

Battery replacement

The 2019 GMC Acadia key fob uses a CR2032 coin cell battery. Here's how to replace it:

1. Locate the small release button or tab on the side or bottom of the key fob. Press it to release the emergency key blade. Pull the key blade out.
2. With the key blade removed, you'll see a small slot or notch. Use a flat-head screwdriver or a coin to gently pry apart the two halves of the key fob casing.
3. Carefully separate the halves, taking note of the battery's orientation (positive side up/down).
4. Remove the old CR2032 battery and insert a new one, ensuring it's oriented correctly.
5. Snap the two halves of the key fob back together until they click securely.
6. Reinsert the emergency key blade.

Where to buy a replacement fob

When looking for a replacement key fob for your 2019 GMC Acadia, you have several options, each with pros and cons:

• GMC Dealership:

  • Pros: Guaranteed genuine OEM part, often comes with programming included (though inquire about costs). They will ensure the correct part number and may provide a warranty.
  • Cons: Most expensive option. Expect to pay anywhere from $200 - $350 or more for the fob itself, plus potential programming and key cutting fees.

• Independent Locksmith:

  • Pros: Often significantly cheaper than a dealership for both the fob and programming. Many locksmiths can cut the emergency key blade and program the fob on-site or at their shop.
  • Cons: Quality of aftermarket fobs can vary. Ensure the locksmith uses a reputable brand or offers a warranty on their parts and labor. Prices typically range from $150 - $250, including the fob, cutting, and programming.

• Online Retailers (Amazon, eBay, specialized key sites):

  • Pros: Potentially the cheapest option for the fob itself (often under $50 - $100). Wide selection of both OEM and aftermarket options.
  • Cons: You're responsible for verifying the correct FCC ID and part number. You'll still need to pay for key cutting (if applicable) and programming separately, which could negate some of the savings if you're not doing the programming yourself. Be wary of counterfeit or low-quality fobs.

If on-board programming isn't supported

While the 2019 GMC Acadia generally supports DIY on-board programming for additional remotes, if you lose all your keys or encounter issues, you may need professional help. The key fob contains a transponder chip (often integrated into the circuit board) that works with the vehicle's immobilizer system. This system prevents the car from starting without the correct transponder signal.

In such cases:

• Professional Programming: A dealership or locksmith can use a specialized scan tool to program new keys and remotes to your vehicle's immobilizer system. This is necessary if you have no working keys or if the on-board procedure fails.
• Cost Expectations: If you require a locksmith or dealer to program due to a lost key or other issue, expect costs to be higher than DIY programming. A locksmith might charge $75 - $150 for programming alone, while a dealership could be similar or higher. This is on top of the cost of the key fob and any necessary key cutting.
