2020 Chevrolet Silverado 1500 Key Fob Programming Guide

Quick reference

Step-by-step on-board programming

The 2020 Chevrolet Silverado 1500 allows for DIY key fob programming, which can save you a trip to the dealership or locksmith. This procedure will program the remote functions of your new key fob. Keep in mind that if your fob has an integrated key, that key will still need to be cut by a locksmith or dealer to match your vehicle's ignition.

To program a new key fob using the vehicle's infotainment system:

1. Ensure all existing key fobs are with you in the vehicle.
2. Close all vehicle doors.
3. Insert your working, cut key into the ignition (if applicable for your new fob).
4. Turn the ignition to the "ACC" position (accessory).
5. Using the steering wheel controls, navigate to the "Vehicle Information" menu on your driver information center.
6. Scroll through the options until you find "Remote Key Learn" or "Remote Control Programming." Select this option.
7. The system will prompt you to press and hold the "Lock" and "Unlock" buttons simultaneously on the new key fob you wish to program.
8. Hold the buttons until the vehicle chirps or a message appears on the driver information center confirming successful programming.
9. Repeat step 7 for any additional new key fobs you wish to program.
10. Once all fobs are programmed, turn the ignition to the "OFF" position and open and close the driver's door to exit programming mode.

If your vehicle does not have the "Remote Key Learn" option in the infotainment system, or if you are programming a new transponder key (where the actual key blade has a chip), you will need a diagnostic scan tool. In this scenario, a professional locksmith or dealer is required to program the transponder to your vehicle's immobilizer system.

Battery replacement

When your key fob starts to lose range or becomes unreliable, it's likely time to replace the battery. The 2020 Chevrolet Silverado 1500 uses a CR2032 coin cell battery.

1. Locate the small notch or opening on the side of the key fob case.
2. Insert a small flathead screwdriver or coin into the notch and gently twist to pry open the two halves of the fob.
3. Carefully remove the old CR2032 battery. Note the orientation of the positive (+) and negative (-) sides.
4. Insert the new CR2032 battery with the positive (+) side facing up (it usually has text on it).
5. Align the two halves of the key fob case and press them firmly together until they click securely into place.
6. Test the new battery by attempting to lock and unlock your vehicle.

Where to buy a replacement fob

• Chevy Dealership: This is often the most expensive option, but ensures you get a genuine OEM part. They will also be able to cut and program the key/fob for you. Expect to pay anywhere from $200-$400+ for the fob, cutting, and programming.
• Automotive Locksmith: Locksmiths often offer a more economical solution than dealerships. They can provide and program aftermarket fobs, and cut new key blades, typically at a lower cost than the dealer. Prices can vary but are often in the $150-$300 range for the fob and programming.
• Online Retailers (e.g., Amazon, KeylessOption.com): You can often find aftermarket fobs at significantly lower prices online, sometimes as low as $30-$70. However, you'll then need to factor in the cost of cutting the key (if applicable) and programming. While the remote functions can be DIY programmed, if your new fob has an integrated key that needs to be cut or if a new transponder chip needs programming, you'll still need a locksmith or dealer. Be sure to verify the FCC ID and compatible part numbers before purchasing to ensure it's the correct fob for your Silverado.

If on-board programming isn't supported

If your 2020 Chevrolet Silverado 1500 model doesn't offer the "Remote Key Learn" option in the infotainment system, or if you're dealing with a transponder chip within the key itself, professional programming is necessary. This involves special diagnostic equipment to communicate with the vehicle's immobilizer system. The immobilizer is a security feature that prevents the engine from starting without a correctly programmed key. Attempting to bypass this can damage the vehicle's electronics.

Cost Expectations:

If professional programming is required, expect to pay for both the key fob itself (if not already purchased) and the programming service. As mentioned above, locksmiths are generally more affordable than dealerships for these services, with total costs ranging from $150 to $400 depending on the complexity and whether you require a new key blade cut and programmed for the immobilizer.
