1. Understanding Your 2000 Chevy Silverado Key Fob

The key fob for your 2000 Chevy Silverado is more than just a remote; it’s your gateway to convenient vehicle access and security. Understanding its functions and how to program it is essential for every Silverado owner. Let’s dive into the details.

1.1. Key Fob Basics

A key fob, short for “keychain fob,” is a small electronic device used to remotely control various functions of your vehicle. For the 2000 Chevy Silverado, the key fob typically includes buttons for:

• Locking the doors
• Unlocking the doors
• Activating the panic alarm

Some models may also include a remote start feature. Knowing these basics is the first step in troubleshooting or reprogramming your key fob.

1.2. Why Reprogram Your Key Fob?

There are several reasons why you might need to reprogram your key fob:

• Battery Replacement: Sometimes, after replacing the battery in your key fob, it may lose its programming.
• Lost or Stolen Fob: If you lose a key fob or it gets stolen, reprogramming ensures the old fob no longer works with your vehicle, enhancing security.
• New Key Fob: When you purchase a new key fob, it needs to be programmed to communicate with your Silverado’s computer system.
• Malfunctioning Fob: Occasionally, a key fob might malfunction and require reprogramming to restore its functionality.

1.3. Identifying Your Silverado’s Body Style

Before you begin the programming process, it’s crucial to identify whether your 2000 Chevy Silverado has the “New Body Style” or the “Classic Body Style.” This distinction affects the programming procedure.

• New Body Style: This is the redesigned model introduced in 1999 and continued into 2000. It features a more rounded and aerodynamic exterior.
• Classic Body Style: This refers to the older body style, also known as the GMT400 platform, which was phased out but still available in 2000 as a continuation model.

Consult your vehicle’s documentation or compare its appearance to online images to determine the correct body style.

1.4. Tools and Equipment Needed

Before starting the programming process, gather the necessary tools:

• Your 2000 Chevy Silverado Key Fob: Ensure you have all the key fobs you want to program.
• Vehicle Key: You’ll need the key to turn the ignition.
• Jumper Wire (for Classic Body Style): A simple wire to connect two pins in the Data Link Port.
• Data Link Port Location (for Classic Body Style): Under the driver’s side dashboard.

2. Programming a 2000 Chevy Silverado Key Fob: New Body Style

If you’ve determined that your 2000 Chevy Silverado has the New Body Style, follow these steps to program your key fob. This method is relatively straightforward and can be completed in a few minutes.

2.1. Step-by-Step Instructions

6. Turn Ignition to OFF: Turn the ignition switch to the OFF position.

7. Turn Ignition to ON (Again): Turn the ignition switch back to the ON position.

8. Turn Ignition to OFF (Again): Turn the ignition switch back to the OFF position.

• Door Lock Button: Verify that the power unlock button on the door panel is functioning correctly.

3. Programming a 2000 Chevy Silverado Key Fob: Classic Body Style

For those with the Classic Body Style 2000 Chevy Silverado, the programming procedure involves using the Data Link Port (DLP), also known as the OBDII port.

3.1. Locating the Data Link Port
