2022 GMC Sierra 1500 Key Fob Programming Guide

Quick reference

Step-by-step on-board programming

Unfortunately, the 2022 GMC Sierra 1500 does not support DIY on-board programming for its key fobs. This means you will not be able to program a new key fob yourself using a series of ignition cycles or button presses. Instead, programming requires specialized diagnostic equipment typically found at a GMC dealership or a professional automotive locksmith.

The reason for this is primarily due to advanced vehicle security systems, including the immobilizer, which are designed to prevent vehicle theft. These systems require specific software and procedures to link a new key fob to your vehicle's computer.

Battery replacement

Replacing the battery in your 2022 GMC Sierra 1500 key fob is a straightforward process:

1. Locate the small release button or tab on the side or back of the key fob. Press it to release the emergency key blade. Pull the key blade out.
2. With the key blade removed, you should see a small slot or indentation. Carefully use a flathead screwdriver or a coin to pry apart the two halves of the key fob casing.
3. Once opened, you will see the circuit board and the CR2032 coin cell battery. Note the orientation of the battery (usually positive side up).
4. Gently remove the old battery and insert the new CR2032 battery with the correct orientation.
5. Align the two halves of the key fob casing and press them firmly together until they click securely into place.
6. Reinsert the emergency key blade into the fob until it locks.

Where to buy a replacement fob

When considering where to purchase a replacement key fob for your 2022 GMC Sierra 1500, you have several options, each with pros and cons:

• GMC Dealership:

  • Pros: Guaranteed genuine OEM part, expert programming services. They will have the exact fob for your vehicle.
  • Cons: Most expensive option. Expect to pay anywhere from $250 to $400+ for the fob and programming.

• Automotive Locksmith:

  • Pros: Often more affordable than a dealership. Locksmiths have the necessary diagnostic tools to program most modern key fobs. They can also cut the integrated key blade on-site. Many offer mobile services, coming to your location.
  • Cons: Prices can vary. Ensure the locksmith is reputable and experienced with newer vehicle security systems. Ballpark cost for a fob and programming could range from $180 to $350.

• Online Retailers (e.g., Amazon, eBay, specialized key fob sites):

  • Pros: Potentially the cheapest option for the fob itself. You can find OEM or good quality aftermarket fobs.
  • Cons: You still need to pay a locksmith or dealer for programming and key cutting. There's a risk of purchasing an incompatible or counterfeit fob. Aftermarket fobs can sometimes have issues with range or durability. The cost of a fob alone might be $50-$150, but remember to factor in programming and cutting costs, which makes the total closer to the locksmith's price point.

If on-board programming isn't supported

As established, your 2022 GMC Sierra 1500 requires professional programming. Here's what that entails and cost expectations:

• Cost Expectations: As detailed above, a dealership will be the most expensive, followed by an automotive locksmith. Always get a clear quote that includes both the cost of the key fob (if purchasing through them) and the programming service.

• Immobilizer Transponder: The key fob for your Sierra 1500 contains a transponder chip that communicates with your vehicle's immobilizer system. This system is a critical anti-theft feature. When a new key fob is programmed, the vehicle's computer learns and validates the unique code from the new transponder. Without proper programming, even if the remote functions work, the vehicle's engine will not start because the immobilizer will prevent it.

• Key Blade Cutting: If you purchase a key fob with an integrated emergency key blade (which most do for the Sierra 1500), this blade will need to be cut to match your vehicle's ignition and door locks. This service is typically performed by a dealership or a locksmith and is usually a separate charge or included in a package price for programming.
