2023 Chevrolet Silverado 1500 Key Fob Programming Guide

As an ASE-certified electrical technician and automotive locksmith, I frequently get questions from truck owners about adding or replacing a smart key for their newer pickups. The 2023 Chevrolet Silverado 1500 uses an advanced proximity smart key system tied into GM’s Global B electrical architecture (CAN FD). Because of this advanced security, programming a new fob isn't as simple as it was a decade ago, but you still have a few options depending on what you currently have.

Here is your comprehensive guide to the 2023 Chevrolet Silverado 1500 key fob, including part numbers, battery replacement, and programming procedures.

Step-by-step on-board programming

General Motors allows you to program a new remote yourself, but for security reasons on the 2023 Silverado, you must already have two working key fobs to program a third on your own. If you have lost all your keys or only have one working key, on-board programming is locked out, and you will need a locksmith or dealer.

If you have two working fobs and an unprogrammed third fob, follow these steps:

1. Insert the two recognized (working) fobs into the backup pocket. In the 2023 Silverado (with center console), this pocket is typically located at the bottom of the center console storage bin or the cupholder (check your specific owner's manual for the exact backup pocket location).
2. Turn the ignition on (without starting the engine) by pressing the START/STOP button.
3. Using the steering wheel controls, navigate to the Driver Information Center (DIC) and find the "Options" or "Settings" menu, then select "Remote Key Learning."
4. The DIC will display "Ready for Remote #3" (or #4, #5, etc.).
5. Remove the two working fobs from the backup pocket and place the new, unprogrammed fob into the pocket.
6. Press the START/STOP button. When the new fob is learned, the DIC will indicate that it is ready for the next remote, or the horn will chirp.
7. Remove the newly programmed key and press the UNLOCK button to verify it works.
8. Press and hold the START/STOP button for 12 seconds to exit programming mode.

Note: If your truck does not display "Remote Key Learning," your specific trim or region may have this feature disabled, requiring professional programming.

Battery replacement

When your Silverado's cluster tells you your key battery is low, it’s a quick fix. You will need one CR2032 coin cell battery.

1. Press the small silver button on the side or back of the smart key to release the emergency metal key blade. Pull the blade out.
2. Look inside the slot where the key blade was resting. You will see a small pry point.
3. Use a flathead screwdriver (or the tip of the key blade itself) to gently twist and pry the two halves of the fob shell apart.
4. Remove the circuit board and the old CR2032 battery.
5. Insert the new CR2032 battery with the positive (+) side facing down toward the back cover.
6. Snap the two halves of the shell firmly back together and reinsert the emergency key blade.

Where to buy a replacement fob

The Dealership:

• Pros: Guaranteed OEM part, right the first time, exact match to your VIN.
• Cons: Very expensive. An OEM smart key for a 2023 Silverado, plus cutting and programming, can easily run between $350 and $500+.

Automotive Locksmith:

• Pros: Mobile service comes to you. They often carry both OEM and high-quality aftermarket fobs, saving you money. Total cost is usually around $200 to $300.
• Cons: You must ensure they have the proper equipment for 2022+ GM CAN FD systems.

Amazon or Online Retailers:

• Pros: Extremely cheap for the part itself ($30 to $80).
• Cons: High risk of buying a defective or incorrect frequency key. Many locksmiths will not guarantee programming on customer-supplied parts, and you still have to pay for the programming and key cutting.

If on-board programming isn't supported

If you only have one working key or have lost all your keys, the DIY method above will not work.

The 2023 Chevrolet Silverado utilizes GM’s Global B architecture. The immobilizer transponder system is highly advanced, requiring specialized scan tools that communicate over the CAN FD protocol. A professional locksmith or the dealer will connect a diagnostic tool to your truck's OBD-II port, connect to GM's secure servers, and force the truck's Body Control Module (BCM) to securely learn the new key credentials.

Expect to pay a professional for about an hour of labor for this service, on top of the cost of the smart key and cutting the high-security HU100 emergency blade.
