2017 Chevrolet Silverado 3500HD Key Fob Programming Guide

Quick reference

Step-by-step on-board programming

Unfortunately, the 2017 Chevrolet Silverado 3500HD does not support on-board programming for key fobs. This means you cannot program a new key fob yourself using a series of key turns or button presses. A specialized diagnostic scan tool is required to communicate with your vehicle's Body Control Module (BCM) and add new key fob information.

This process typically requires advanced equipment that a dealership or an automotive locksmith will possess. Attempting to program a fob without the correct tools can lead to issues with your vehicle's security system or even render the fob unusable.

Battery replacement

1. Locate the seam: The key fob has a seam running along its side. You may see a small indentation for a screwdriver or coin.
2. Pry open the case: Carefully insert a small flat-head screwdriver or a coin into the indentation and gently twist to separate the two halves of the fob case.
3. Remove the old battery: Note the orientation of the battery (usually positive side up), then carefully pry it out.
4. Insert the new battery: Place the new CR2032 battery into the compartment with the positive (+) side facing up, matching the orientation of the old battery.
5. Snap the case back together: Align the two halves of the key fob and press them firmly together until they click securely into place.

Where to buy a replacement fob

• Dealership:
  • Pros: Guaranteed genuine OEM part, often comes with programming included.
  • Cons: Most expensive option. Expect to pay anywhere from $150-$300 for the fob itself, plus an additional $75-$150 for programming.
• Automotive Locksmith:
  • Pros: Generally more affordable than the dealership, often provides mobile service, and can cut and program keys on-site. Offers both OEM and quality aftermarket options.
  • Cons: Prices can vary, so it's wise to get a quote first.
• Online Retailers (e.g., Amazon, eBay):
  • Pros: Widest selection and often the lowest prices for the fob itself (as low as $20-$60 for aftermarket options).
  • Cons: You're responsible for verifying compatibility (matching FCC ID and part numbers is crucial). You'll still need to pay for cutting and programming separately, which can negate some of the savings.

If on-board programming isn't supported

As established, on-board programming is not available for your 2017 Chevrolet Silverado 3500HD key fob. This means professional assistance is a necessity. Here's what to expect:

• Cost Expectations: The total cost for a new key fob, cutting, and programming from a locksmith typically ranges from $150 to $250. Dealerships will generally be higher, often $250 to $450 or more. These costs can fluctuate based on your location and the complexity of the service.
• Immobilizer Transponder: Your Silverado's key fob contains a transponder chip (part of the security system). This chip communicates with your vehicle's immobilizer system. When a new key fob is programmed, the transponder chip's unique code is registered with the vehicle's computer. This encrypted communication prevents the engine from starting if an unauthorized key is used, even if the key blade can physically turn the ignition.
