2022 GMC Acadia Key Fob Programming Guide

Welcome to your complete key fob programming and replacement guide for the 2022 GMC Acadia. As a professional locksmith and ASE-certified electrical technician, I've programmed countless GM proximity keys. The 2022 Acadia uses a modern push-to-start proximity smart key system. Fortunately, General Motors still allows you to perform on-board programming at home in many situations, saving you time and money.

Quick reference

Step-by-step on-board programming

For US-market 2022 GMC Acadia models, you can program a new key fob yourself if you already have two currently working key fobs. If you only have one working fob (or zero), the vehicle's security system restricts DIY programming to prevent theft, and you will need a scan tool.

How to Add a Third Key (Requires Two Working Keys):

1. Ensure the vehicle is off and you have both working key fobs, plus the new unprogrammed fob, inside the vehicle.
2. Remove the rubber mat inside the center console storage bin. Locate the transmitter pocket (a small slot shaped like the key fob).
3. Insert the first working key fob into the transmitter pocket.
4. Press the engine START/STOP button while pressing the brake pedal. Wait until the engine starts, then turn the vehicle off.
5. Remove the first key fob. Insert the second working key fob into the pocket.
6. Press the engine START/STOP button with the brake pedal. Wait until the engine starts, then turn the vehicle off.
7. Remove the second working fob. Insert the new, unprogrammed key fob into the pocket.
8. Press the engine START/STOP button. The Driver Information Center (DIC) on your dashboard will display "READY FOR REMOTE #3" (or 4, 5, etc.).
9. Press the START/STOP button again to finalize programming.
10. Remove the new key fob and press the UNLOCK button on the remote to verify it works.

Note: If your DIC does not display the programming prompt, your specific trim or region may have on-board programming disabled, requiring a professional.

Battery replacement

If your Acadia is failing to detect the fob or the range has significantly decreased, you likely just need a new battery.

1. Press the small silver release button on the side of the fob and pull out the metal emergency key blade.
2. Look at the bottom of the fob where the key blade was inserted. You will see a small pry slot.
3. Insert a flathead screwdriver into the slot and gently twist to split the two halves of the remote apart.
4. Remove the old battery and insert a new CR2032 battery with the positive (+) side facing down toward the back cover.
5. Snap the two halves of the fob back together and reinsert the emergency key blade.

Where to buy a replacement fob

When replacing your 2022 GMC Acadia key fob, you have three primary routes:

• The Dealership: Guaranteed to get the correct OEM part (HYQ1EA / 13529633). However, this is the most expensive route. Expect to pay $150–$250 for the fob, plus another $100–$150 for programming and cutting.
• A Local Automotive Locksmith: Locksmiths can supply OEM or high-quality aftermarket fobs (like Strattec). They will come to you, cut the emergency blade, and program the fob using advanced diagnostic tools. Usually 20–30% cheaper than the dealer.
• Online (Amazon / eBay): You can buy aftermarket fobs online for $30–$80. Pros: Extremely cheap. Cons: Quality is hit-or-miss. Also, you will still need a locksmith to laser-cut the emergency blade and program it if you don't have two working keys.

If on-board programming isn't supported

If you have lost all your keys, only have one working key, or your Acadia's BCM software locks out DIY programming, you cannot use the center console pocket method. Because the 2022 Acadia uses an encrypted Hitag 3 / 433 MHz immobilizer system, bypassing this requires an automotive scan tool with an active NASTF/GM SPS2 subscription.

Expect to pay a mobile locksmith or dealer around $100 to $180 for the programming service alone. A professional will connect to the OBD2 port, authenticate with GM's servers, and pair the new transponder directly to the vehicle's immobilizer module.
