Understanding Key Fob Programming for Your 2001 GMC Sonoma

Before we dive into the how-to, let’s understand some basics. Your 2001 GMC Sonoma key fob uses radio frequencies to communicate with your vehicle’s security system. When you press a button, the fob transmits a unique coded signal to the receiver in your truck. If the code matches, the corresponding action is performed (locking/unlocking doors, panic alarm, etc.). Reprogramming involves teaching your vehicle’s receiver to recognize the unique code of your key fob. This is often necessary if you replace a lost or damaged fob, or if the fob’s battery has been replaced. You may find that replacing the 2001 gmc sonoma key fob battery is simpler than reprogramming.
