I have the same 2002 GMC Sierra 2500 Extended and I'm also trying to find the key code.

Same issue here. Let’s hope it works for my 2002 GMC Sierra 2500 Extended.

Got a dead key fob for my 2002 GMC Sierra 2500 Extended. Need the code badly.

Anyone have luck with this on a 2015 2002 GMC Sierra 2500 Extended?

🔑 Car Key & Fob FAQ

Common questions about key programming, fob issues, and replacement options

Key Fob Issues
1) Find the seam and pry open the fob (some have tiny screws) 2) Note battery orientation 3) Remove old battery (CR2032 is most common) 4) Insert new battery 5) Reassemble. Test all buttons - if issues remain, the fob may need reprogramming.
Key Tip: Always have at least two working keys to avoid expensive replacements
Security Systems
Not recommended. Bypassing requires specialized knowledge and may violate anti-theft laws. Proper solutions: 1) Get correctly programmed keys 2) Replace faulty immobilizer components 3) Have dealer reset the system if keys are lost.
Key Tip: Replace key fob batteries every 1-2 years as preventative maintenance
Key Programming
Programming syncs the key's transponder chip with your car's immobilizer system. The process varies by manufacturer but generally involves: 1) authenticating with the car's computer 2) erasing old keys if needed 3) programming new key codes 4) testing functionality.
Key Tip: Replace key fob batteries every 1-2 years as preventative maintenance
Key Fob Issues
Common causes: dead battery (most common), water damage, internal circuit damage, or the fob lost synchronization with your car. Try replacing the battery first. If that doesn't help, the fob may need reprogramming or replacement.
Key Tip: Consider key insurance for expensive smart keys
Cost & Options
Locksmiths are typically 30-50% cheaper than dealerships for key replacement and programming. However, some newer models (especially luxury brands) may require dealer-only programming tools. Always get quotes from both.
Key Tip: Always have at least two working keys to avoid expensive replacements
Key Fact: The average driver will lose 1-2 car keys during ownership
