2016 Chevrolet Silverado 3500HD — Key Fob Programming

Quick reference

Step-by-step on-board programming

DIY on-board programming is not supported on the 2016 Silverado 3500HD. GM paired these remotes through the Body Control Module (BCM), and the truck must be placed in a learn mode using a scan tool. A dealer or automotive locksmith with a GM-capable programmer is required.

If you want to understand the process your locksmith/dealer will follow, it generally looks like this:

1. Gather all remotes you want to work. During programming, previously learned remotes may be erased—have them all present.
2. Connect a GM-capable scan tool to the OBD-II port (above the driver’s left knee) and turn the ignition ON (engine off).
3. In the scan tool menu, navigate to Body/BCM or Remote Control Door Lock Receiver (RCDLR) functions, then select Program/Setup Key Fobs (terminology varies by tool).
4. Follow on-screen prompts to enter Remote Learn Mode. When prompted, press and hold the LOCK and UNLOCK buttons on the remote being added for ~5–10 seconds until the locks cycle or the tool confirms success.
5. Repeat step 4 for each additional remote.
6. Exit learn mode on the scan tool and cycle ignition OFF, then start the truck and test each remote (lock/unlock, remote start if equipped, panic).

Note: If you are also adding a new ignition key, that is a separate immobilizer programming procedure. A 10/30-minute on-board key relearn is possible on many GM trucks if you have no working keys, but that does not program the RKE fob—only the transponder in the key.

Battery replacement

Most 2016 Silverado HD remotes use a single CR2032.

1. Locate the case seam or small notch on the edge of the fob. Insert a plastic pry tool or small flat screwdriver.
2. Gently twist to split the case. Work around the perimeter to avoid cracking the shell.
3. Lift out the coin cell and note orientation before removal (typically positive “+” faces up, but confirm yours).
4. Install a fresh CR2032 without touching the faces (skin oils can shorten life). If there’s a rubber gasket, seat it properly.
5. Snap the shell together, then test lock/unlock near the truck. No reprogramming is needed after a battery swap.

Where to buy a replacement fob

• Dealer (Chevrolet):

  • Pros: Guaranteed correct by VIN; brand-new OEM; latest software bulletins if needed.
  • Cons: Highest price; programming fee. Expect $120–$200 for the fob plus $90–$160 for programming.

• Automotive locksmith:

  • Pros: Mobile service; competitive pricing; can supply OEM or quality aftermarket; can cut/program keys and fobs on-site.
  • Cons: Quality varies—choose a well-reviewed locksmith. Expect $60–$140 for an aftermarket or used-OEM fob plus $70–$130 to program.

• Online (Amazon/eBay/parts retailers):

  • Pros: Lowest parts cost, widest selection.
  • Cons: You still need it programmed with a scan tool; risk of wrong FCC ID or a locked/incorrect unit. Vet sellers, and buy only listings that clearly state the FCC ID and compatibility for 2016 Silverado 3500HD.
  • Typical pricing: $25–$70 for aftermarket; $60–$140 for new OEM; $25–$60 for used OEM (ensure it’s re-usable).

If on-board programming isn’t supported

• What to expect: You’ll need a dealer or locksmith to pair the remote to the truck’s BCM. The job typically takes 15–30 minutes if you already have the correct fob.
• Costs: Plan on $100–$250 total with a locksmith (fob + programming) or $180–$350 at the dealer, depending on parts and local labor rates.
• Immobilizer note: The remote fob only handles locks/remote start. Starting the truck is authorized by the transponder embedded in the ignition key. On most 2016 Silverado HD models, that transponder is GM PK3+/Philips 46 crypto. Keys must be cut to your truck and then programmed (scan tool or a timed relearn procedure). Keys and remotes are programmed separately.
• Used fobs: Some GM remotes can be re-used; others are effectively locked once paired. Minimize hassle by buying new OEM or aftermarket that explicitly matches your FCC ID and button count, or confirm with the seller that the used OEM remote is “virgin”/resettable.
• Bring your VIN: Whether you call a dealer or locksmith, have your VIN handy. It ensures you get the correct OEM part number and confirms frequency/button configuration for your exact trim (WT, LT, LTZ, High Country, remote-start or not).
